8 Best Head Studs for 6.0 Powerstroke [2021 Buying Guide]

Head studs are an often overlooked component of vehicles. Upgrading your head studs is extremely important if you intend on using turbo boosts.

Head studs allow you to properly clamp loads. They twist in a single direction and thus allow for much more accurate clamping. They can also bear higher turbo pressures, which allows them to handle heavy-duty vehicles as well.

For engines such as the Powerstroke 6.0, head studs become extremely important. Powerstroke 6.0 is a heavy-duty engine and packs 325 horsepower.

Any turbo boost without the usage of some of the best head studs can lead to gasket failure. This can dangerous and might cause damage to your vehicle as well.

That is why we have compiled a list of some of the best head studs for your Powerstroke 6.0. With these models, you can ensure that your boosts are reliable and without caps on them.

1. ARP 247-4202 Stud Kit

APR 247-4202 Stud Kit


ARP is well known in the industry for their stud kits that tend to excel. The ARP 247-4202 is no exception. The stud kit is one of the finest that we have seen and comes at a reasonable price tag.

The head studs offered by ARP are made from an 8740 alloy, which is rated as superior quality. The head studs will not break or rust easily and will last you a long time.

They are also inherently superior to most studs built into engines. These studs have been made for cars that require supercharge or nitro boosts, and do their job right. They can handle up to 700 horsepower, which should easily handle most of your engine needs.

However, they can’t handle higher horsepowers, and you may want to consider an alternative product for any higher requirements. They should work perfectly for your Powerstroke 6.0 though.

The studs can also hold a lot of pressure. They have a rated tensile strength of 200,000 psi. This is not the best that we have seen in the market but should be more than enough for your Powerstroke engine.

One of the best things about these studs is their making. These studs have been treated and made perfectly concentric. The studs are also cut straight and made to fit. The studs can thus easily align the cylinder heads and the gasket with no errors.

The ARP head studs 6.0 Powerstroke kit comes with lubricant as well. Which should be more than sufficient for your needs. The lubricant works well with the studs and is a nice extra.

The studs also have a high fatigue strength. This is because they are threaded after being heated. This greatly enhances their strength and allows them to last longer.

The kit is technically assembled for a Dodge Ram 2500 but will fit a lot of other engines as well. These include Powerstroke 6.0. It should also fit any other engines with similar dimensions.

The head studs come with a partial warranty, which would allow you to replace them in case of manufacturing defects. This is only a partial warranty and not the best that we have seen. We would have expected a better warranty from ARP.

The studs are reasonably priced. They are mid-range and offer a lot of value. There are better options available in terms of tensile strength and horsepower ratings, but those are typically much more expensive and reserved for very powerful engines.

For your Powerstroke 6.0 though, these should be perfect!

  • Good quality
  • Up to 700 Horsepower
  • 200,000 rated tensile strength
  • Great value option
  • Not suited for the most powerful engines
  • Not the best warranty options

2. ARP 250-4202 Stud Kit

APR 250-4202 Stud Kit


This kit is similar to the ARP 247 in a lot of ways. It offers the same reliability, value, and is made for your Powerstroke. However, some issues push it a little lower in our list of the best Powerstroke 6.0 head studs.

The kit is made from the 8740 alloys, similar to the 247 variant. The similarities are also observed across several other variables. The studs are similarly cut, centered, and pre-heated to give them the best finishing touches.

However, the quality control for this product lacks significantly. While the products that are prepared perfectly should last you a reasonably long time, many products are simply not cut or centered right and will stretch or break.

These products would not be a good addition to your vehicle. They can lead to the disconnection of or damage to the gasket or exhausts. You should look into a product with better quality control if you are not experienced with stud kits and wouldn’t be able to note defects.

Amazon does offer returns, so you should check these head studs as soon as you receive them. While a warranty for non-manufacturing defects is not offered, you can still get replacements for defects out of the box.

If you manage to land yourself a good product, you would find this kit to be fitting to your needs. One of the reasons that the ARP 250 kit is recommended is because it is made to fit Ford. The product is technically for a Ford F350, but will easily fit your Powerstroke engine as well.

The studs are rated at 700 Horsepower and 200,000 tensile strength. These are in line with the first product. These limits are perfect for your Powerstroke 6.0 version, but would not be fitting for engines with higher turbo powers.

The studs are coated with a black oxide finish, which makes them appealing. However, you should note that oxide finishes tend to rust. Your head studs will eventually get rusty.

The product costs at par with our top pick, which was expected given the similarities in composition. Both the products offer a lot of value in a small price tag, and we recommend that you look through them.

We recommend this product for anyone that can quickly test the quality of the studs and ensure they won’t stretch or break. When not defective, these studs would be your Powerstroke 6.0 partner.

  • High quality
  • Great value
  • Up to 700 Horsepower
  • 200,000 psi tensile strength
  • Inadequate quality controls
  • Tends to rust
  • Limited warranty

3. Sunluway 6.0 Powerstroke Head Stud Replacement Kit

Sunluway 6.0 Head Stud


The Sunluway replacement kit is the perfect kit for anyone that wants to replace damaged head studs. The value kit will fit your engine perfectly, and get it running smoothly again.

The kit contains all the head studs that you would need for your Powerstroke 6.0. It can also fit other models such as the 2003-2007 Ford, Ford F250, F350, F450, F550, and E350. This makes these studs perfect for anyone seeking a replacement kit for Ford.

The kit is made from a Chrome Moly 8740 alloy, which gives it added strength. It is also covered in an oxide exterior to prevent wear and tear. Despite these properties though, the quality does seem questionable.

While the control over quality is great, the quality itself tends to run down very quickly. The products will work perfectly for a year or so, but will then start to bend or stretch. This makes their life lower than most other studs. The oxide also tends to rust.

The studs in the 6.0 Powerstroke head stud kit are centered, and will thus provide optimal and smooth gliding between the gasket and exhaust. The perfect concentricity is assisted by 220,000 psi tensile strength, which makes this stud one of the most reliable ones that we have come across. It can work on more powerful engines too.

The studs come with a 30-day return guarantee, which would allow you to claim the full amount when the studs aren’t up to the mark. You get a 12-month warranty in case of defects as well, allowing you the ease of mind.

The studs are also designed to make disassembly easier. This is done to allow for your ease.

These studs are very well equipped to handle almost anything that you can throw at them, and this makes the kit perfect for your everyday needs. As long as you are willing to spend to make replacements once these studs wear out, you are in for a treat!

The most remarkable feature of these studs is their value. They cost half of the ARP models, which is a bargain you should definitely look into!

  • High quality
  • Great Value
  • High tensile strength
  • Concentric
  • 12-month warranty
  • Not Durable
  • Will rust

4. E-Cowlboy 6.0 Powerstroke Head Stud Replacement Kit

E-cowlboy 6.0 Head Stud


If you want all the features of Sunluway, but do not agree with their product, there are few alternatives as good as the E-Cowlboy. The E-Cowlboy replacement kit closely resembles the Sunluway and offers great value for the money you will spend on it.

The product is made from a chrome-moly 8740 alloy and coated with oxide. It prevents wear and tear but can rust.

The product itself is of high quality, and similar to the Sunluway product, it will last you at least a year. It is not the most durable product though, and you will eventually have to replace it.

The reason that this was ranked lower than the Sunluway was because of their quality control issues. The product has been noted to come bent. The low-grade products received can be replaced though.

You are offered a 30 day guaranteed refund. You are also offered a 12-month guarantee, which will ensure that you can exchange the product if you were to find yours defective. This helps safeguard against quality control issues.

The design of the study is meant to assist with boosts. The caps are removable, and the design is very concentric. It will allow smooth and easy gliding.

The threads are rolled after heating, allowing for optimal fatigue strength. The studs can hold 220,000 psi of force with ease, allowing you to get the best out of your product. You can easily use this for high power engines as well.

The psi ratings are greatly reduced if the product is defective though, so you should ensure that you are getting what you opted for.

The kit is made to fit a large number of engines and vehicles. It is technically made for the Powerstroke 6.0, but will also fit Ford 2003-2007, F250, F350, F450, F550, E350, E450, and V8 Diesel.

This wide range of compatible engines can make these studs the perfect studs for your needs, no matter what Ford you own.

The product is available at the same price as the Sunluway. This is incredibly cheap and means that you can get the best out of every dollar that you spend.

  • High quality
  • Great value
  • 220,000 psi tensile strength
  • Concentric
  • Can rust
  • Low quality control

5. MTC Head Stud for Ford Powerstroke 6.0

MTC Head 6.0 Stud Kit


The MTC head studs might not be the best option available in the market, but they offer great value that no one can match. For a measly price, you can get yourself head studs that can be used to reach your turbo potentials.

The product is made from the highest grade MTC proprietary material. This ensures that the product will not break or stretch easily, and can fulfill your head stud needs.

Beyond barely surviving though, the quality is barely anything to boast about. These will not last you a long time and do not feel strong out of the box.

Nonetheless, given the price, you should save even if you were to require replacements oftener than other head studs. The quality is very acceptable given how much of a steal this product is.

The tensile strength or horsepower boosted by this product is not remarkably high. It is not meant for very strong engines, and will not be able to unleash their full potential.

However, it will be sufficient for any Ford Powerstroke 6.0. The studs boast compatibility with a large number of engines and vehicles, and you can find plenty of use for them!

You can use these studs with Ford E-350, E-450, F-250, F-350, F-450, and F-550. It can also handle the tensile strength and horsepower of these models, making it perfect for Ford owners.

The kit includes all the components that you may need for your head studs. It also has good quality control, and all the products will be in optimal conditions.

The best part of these studs is their price though. Despite not being the strongest or best options available in the market, they will save you lots.

The studs cost half the Sunluway, which makes their price very competitive, and puts them in our list of the best head studs for Powerstroke 6.0.

  • High-quality control
  • Great value
  • Will fit most Ford engines
  • Tensile strength is not high
  • Not durable

6. ARP Mahle Powerstroke 6.0 Head Studs and Gasket Kit

APR MAHLE 6.0 Stud Kit


For those seeking to upgrade both their head studs and their gasket kits, there are few better options than ARP Mahle. The two companies are well-reputed, and their combined kit offers great value for anyone seeking an all-in-one solution.

The contents of the kit include a full head stud set as well as a full gasket set. The gasket set includes the exhaust gaskets too. However, the set is missing two crucial items. These are the valve cover and the rocker box gaskets.

The kit says that it is a complete kit but still misses out on these two essential items. This means that you would have to spend more on acquiring those items, and may have to ensure fitting as well. These items should have been included in the set.

The items are all high quality. The head studs are ARP and are made from 8740 alloys. This will last you a long time and does not break or bend easily. The black diamond coated gaskets will definitely last long as well.

The head gaskets are black diamonds by Mahle. They are one of the best available in the market, and will similarly provide you with a high-quality finish. The master intake gasket set included in this kit has O-rings and Turbo hardware in them as well.

The product also comes with lube. The lube is sufficient and you will not need to buy any extra lube for operations.

The head studs themselves are meant to handle a large number of engines and offer remarkable turbo capabilities. They are concentered and well balanced, and the whole kit will assemble easily.

While the kit is made for the Powerstroke 6.0, it will be able to handle many other models of Ford as well as long as they fit. The tensile strength is rated at 200,000 psi, and the studs can handle up to 700 horsepower.

The gasket kit is similarly strongly built and will last you a long time. The kit can be your lasting solution for your Ford Powerstroke engine.

The features do make the product expensive though. It will cost you almost twice as much as the ARP 250-4202. However, this is still great value for anyone seeking to get both a head stud and a gasket kit.

One thing that might be a nuisance for some people is that the product is not shipped at once. The product is instead shipped separately at different times and from different locations. You should keep that in mind before making your purchase.

  • Very high quality
  • High tensile strength
  • Complete head stud and exhaust kit
  • Great value
  • Expensive
  • Ships from different locations
  • A few components are missing

7. ARP 250-4203 Head Stud Kit

APR 250-4203 Head Stud


ARP continues to prove that no one can beat it in quality and keeps making it into our list. This product from ARP is fitting for those that seek a little extra. If you want higher Horsepower and Tensile strength than other products, you should definitely check out the ARP 250-4203.

The ARP 250-4203 is made from the best quality materials and the alloy can withstand a lot of torque, pressure, and turbo. This makes it fitting for heavy-duty engines. It will also last you a long time. It is very durable.

The quality checks of the product are excellent. You can expect every head stud that you receive to be of the perfect quality.

The kit has been concentered and will balance well. This ensures that it will be smooth in operations.

The kit has also been pre-headed and threaded. This ensures that it does not fatigue easily. It will not stretch or break for quite some time.

The kit also offers you some fluid. This is a nice touch and will assist you with the installation. However, the lubricant might not be enough and you may need to buy more for your needs.

Overall, the package has great offerings for anyone that is seeking to get the best out of their engines. It can allow for great boosts and can survive through thick and thin.

However, it does come at a price. The price of this product is almost 1.5 times that of the ARP 250-4202 model. That is why this product was lower on our list.

If you seek to use the studs only on a Powerstroke 6.0, it makes little sense to buy the more expensive variant, since your engine can work perfectly with the ARP 450-4202 as well. If you want to use heavier engines though, you should definitely check these head studs out.

  • High quality
  • Durable
  • Excellent quality control
  • High tensile strength
  • Comes with lubrication
  • Expensive
  • Lubrication might not be enough

8. ARP Head Stud and OEM Head Gasket Bundle

APR Head Stud Kit


ARP continues to impress us with its superior quality products, and this bundle is no different. If anyone seeks a perfect alternative to the ARP Mahle bundle, then there is no better option than the ARP OEM bundle. This bundle can help you with your stud and gasket needs.

The study included in this set is of the highest quality alloy, and will not break or stretch easily. You can ensure that the product you get will last you a long time.

The products are also checked and inspected before being dispatched, so you can expect every product that you get to be of the perfect quality. You don’t have to worry about the studs being bent out of the box.

The head gaskets also offer similar high quality. They are made of steel and coated with black diamonds. The coating further adds to the strength and ensures that they last a long time.

The bundle is a complete kit and would suit your needs perfectly. However, you should opt for this product only if you seek both a head gasket and a head stud bundle.

The studs are concentric and have high horsepower and tensile strengths. You can expect them to provide you with the turbo you require easily on any of the Ford F series, and on the Powerstroke 6.0 versions.

However, they will not work with more powerful engines, and you should seek some other product for that purpose.

The product is priced at 100 dollars under the ARP Mahle bundle. However, the product would also not work with more powerful engines, so the price cut was expected. The value offered by this product is not the best, but it’s a good option if you seek a bundle for your Powerstroke 6.0

  • High quality
  • Durable
  • High tensile strengths
  • Can not work with very strong engines
  • Not the best value

Best Head Studs for 6.0 Powerstroke: Buyer’s Guide

Best Head Studs for 6.0 Powerstroke

Head studs are tricky to buy. You may have already decided upon a certain head stud, but will still often be confused. The confusion mostly comes as a result of the different features that companies claim they offer.

The catalogs of the retailers are also wide, and it can be quite confusing for anyone that does not know this subject. We understand how important head studs are for your engine, and are determined to help you make the right pick.

This guide will highlight important features that you may come across when trying to buy ahead stud and will help you make the right choice.


Head studs don’t always come in similar packages. They might come as kits, bundles, or even alone. It is important to understand what style of head studs you need, and how they would fit your specific requirements.

Single stud/washer

You can buy a single stud, washer, or any other component that you may require. Normally, this is not the product that you would be buying.

However, it can be a useful buy in some very specific cases. For example, when you lost a washer from among the set that you ordered, you could simply place an order for a single washer.

Similarly, if only one head stud was defective from among the package that you ordered, and you get no warranty, you may choose this option. This way, you will be able to get the missing stud without having to buy the whole set again.

Replacement Head Stud Set

A replacement head stud set is typically made to replace a head stud that was already installed in the engine. The purpose of these sets is typically only to replace the studs, and not to improve on them.

The replacement set would be made specifically for one engine. It might still fit others though, but it will be optimized for the engine that you are attempting to replace the studs of.

This option is perfect for you if you feel that your engine studs were good enough but simply wore down after extended use. You can simply get similar studs again by looking for a replacement set.

Head Stud Set

A head stud set is the most commonly bought style of studs. This set would include head studs of a different psi and horsepower rating.

The reason that you may want to opt for this set would be to optimize your turbo. Many engines may not be able to explore the true extent of their turbo due to the studs. The studs would not be compatible with the turbo offered.

By upgrading and getting better studs, you can unlock the true potential of your engine and ensure that it works smoothly.

Head stud and Gasket bundle

A head stud and gasket bundle are typically used by people that want both head studs and head gaskets. Instead of making the purchases individually, you can purchase them in a bundle.

This might let you get both the products at a cheaper price than when they are purchased individually. If you find a bundle to suit your needs, it might be a great chance for you to save some money.

However, the bundles do leave you with little choice over individual components so you should factor that in before making your choice.


Once you have decided upon what style your head studs, it is important to understand what material they are made of. The material of composition is not important in itself but will dictate the durability, tensile strength, and horsepower of the engine.

The most common materials that we see with head studs are alloys. These alloys are a mixture of carbon, nickel, and some other materials.

The alloys that are commonly used in head studs include 4130 Chrome Moly, 8740 Chrome Moly, ARP 2000, L19, and the AMS5842. The table below demonstrates the differences between each of them.

NameCompositionPsi rating
Chrome Moly 413095% Chromium
3% Carbon
Under 200,000
Chrome Moly 874053% Chromium
43% Nickel
4% Caron
ARP 2000Temper steel at high temperatures220,000
Vacuum melted alloy
220,000 to 260,000
AMS5842Multi-phase non-steel austeniticOver 260,000

Tensile strength

The tensile strength is the psi rating of the studs.

In technical terms, Psi is the pressure applied in pounds, per square inch of area. The psi ratings of any head stud would thus tell you how much pressure it would apply to keep your engine clamped, on every square inch of area.

The reason that Psi ratings are mentioned is that they dictate what studs you might need for your engine.

Technically speaking, you would be safe with any stud that rates near 200,000 psi. Very few engines tend to cross this limit. For a Powerstroke 6.0, you won’t need anything more than that.

For a race car engine or any other power-packed engine though, you may need higher psi ratings. It is always a good idea to aim a little higher in case you are unsure. The higher clamping pressure would ensure your engine sticks in place!

Horsepower rating

Most studs would be able to handle only up to a specific amount of horsepower. This is typically dependent on the Psi as well. When a stud has a higher Psi, it can handle more pressure and would thus be able to take more horsepower.

The Powerstroke 6.0 is a 325 horsepower engine. This means that you would be fine using any of the studs that we have listed above. Most studs tend to be able to handle up to 600 horsepower with ease.

If you have a racecar or any other such powerful engine, you may want to opt for a better stud though. Many studs can handle the greater horsepower and can ensure that your engine is clamped tight.


The purpose of a stud’s concentricity is to ensure balance. When a stud is concentric, it will not be obstructive, and it will attach the gaskets and the engines very smoothly.

Concentricity is important for smooth operation. If the studs are concentric, they will balance well and will ensure that your engine keeps running.

You should always seek studs that are concentric. Most studs will be concentric, but adding cuts along the stud can help them become more balanced.


The compatibility of studs with engines technically depends on the nut sizes. The nut sizes must match for the studs to be compatible with the engine. It is, unfortunately, not easy to find the nut sizes for most studs.

For the ARP site, you can typically check the compatibility by entering the set model number into the search bar. This will give you the nut size. For other studs, you can check the size by seeing what compatible engines are listed on the product page.

Fatigue strength

The fatigue strength of the studs depends on when they have been threaded. Studs that have been threaded after they have been heated are typically much stronger.

The fatigue strength ensures that the studs would last you a long time.


The price of stud kits is typically very high. Price is thus an important deciding factor when trying to buy a stud.

You should consider the durability of the stud as well when it comes to price. A stud that costs 100 dollars might not be better than a stud that costs 400 if the 100 dollar stud starts to rust only after a few months!

Studs with 200,000 psi would typically cost under 500 dollars. For prices above that, you can get a higher rated product.
