Subaru Phase 2 EJ Series Head Stud Kit 1988-1994

I installed these studs a week ago. So far so good and I don’t expect it to go any other way. They came very well packaged, with clear installation instructions. The head studs are very well manufactured and are a for sure upgrade to do on your diesel engine. I highly recommend buying some Xotic head studs!

Works amazing and they feel nice and strong

I have these head studs in 2 different Cummins motors running better turbos and tunes. We put about 50k miles a year on each truck pulling trailers more often than not and these studs do an amazing job of keeping the head down and the gasket whole. I will be adding them to my next truck at my earliest convenience.

Great packaging!! Easy well illustrated instructions to follow and packing is really clean and organized.

Arrived quickly

6.7L & 5.9L 24V Dodge Cummins Head Stud Kit 1998.5-Present

The price of these are really good! And they torqued up really nice too! Only thing is the steel is from china but still better than a head bolt.

Worked as expected, cleaned out threads .

This thread chasing set is a very high quality item. This set would be for SAE threads with 5 common thread sizes. They are cut very well so your threads will be spot on.

This set offers a good assortment if it has the sizes you need. There are other sets, too, and the individual sizes are available separately. I have some of the sets, and the quality across them has been consistent. I haven't had a chance to try all of the sizes, but so far the threads look to be cleanly cut.

I am rebuilding a 7.3 and will be putting it in an E-350 that I will be pulling a horse trailer with. These appear to be of excellent quality and are packaged with the threads well protected. I did not do destructive testing but these seem up to the intended task. Recommended.

No problem after few passes

Broken head stud out of no where and this truck is not hot rodded or abused. It sure why it happened

Not sure what the difference is between this thread "chaser" and a tap. I ordered a same size tap from another company and they both looked exactly the same. The tap was also much less expensive than this chaser

I've owned and still own all kinds and levels of taps and thread chasers, from one time use garbage to top of the line expensive stuff. These are on par with some of the better stuff I have in terms of metal quality/hardness, and thread precision. I agree with others that for the price they should have case instead of a simple cardboard bubble pack but the quality of the tools is there otherwise.

I was skeptical because this was an unknown brand to me but the quality is on par with the more well known brand I'm used to based on my initial impressions. It's pretty obvious they have pretty strict quality control measures and hopefully they will expand their product line further. It is nice (although not necessary) that they include a socket and allen key.

The kit includes everything you need with clear and easy instructions. Price point make it even better!

Perfect fit. The studs are well made, and the threads are really solid. The material is strong and the performance has been great.

Great fit, strong & durable, assisted alignment:This product provides a very good fit with applicable ford powerstroke engines, allowing an easier installation thanks to the broached stud ends and detailed instruction manual. The product's materials are also very strong and durable, with a very high tensile strength that allows the studs to withstand the stress from a turbocharger much more effectively than factory provided alternatives, helping to head off gasket failure more effectively and reliably. The product also helps to align the main caps better since the studs remain stationary during clamping, allowing for a more consistent hold and better performance overall.Overall, this is a good set and I would reocmmend.

Great studs. They're well made, have good threads that aren't thin or rough, and the studs themselves are straight and solidly made. They're a perfect fit and seem to have high quality performance.

This stud replacement set is great quality. They fit perfectly, and they're definitely performance quality pieces. They price is worth it.

Have only used one but it worked great! As someone else commented at this price b=point they should come with a box or bag to keep them all togetehr in the tool chest. They just come in a vaccuum sealed cardboard card.

Great great quality kit that comes with everything. It is made better than any other set I have ever seen and is made to last a long time. They have excellent quality control and it's an amazing product that I have used several times but I just can't justify the price when all the competition is a fraction of the cost. Yes quality is a big factor but most people who will be buying this to do on their own do not have the budget to use these great products.

The edges are neatly cut. What you need if you need to clean a fouled screw hole. Comes as a multi-size pack for convenient value, as long as you have a need for all of the sizes.
