Standard Washer 0.31" ID, 0.55" OD, 0.120" Thickness x 3 pcs

Looks great and fast shiping not install yet but look amazing and good price

Appearance, packaging and presentation are great. Minor issue with instructions, but easy enough to figure out if you look up the arp stud install instructions. My directions had 2 number 1 bolts and no number 7 in the torque sequence diagram. They seem to be a good alternative to ARP if you want something a bit more budget friendly. Time will tell.

Great people to work with been sponsoring my trucks on TikTok for a little while now 100% love there products

So far I'm impressed with them. I haven't installed them yet. Was a little concerned when I opened the shipping box and found 3 of the nuts out of the main box. But all was good.

I ordered before pulling my 2004 5.3 LS heads off. I take responsibility for the purchase. However, my particular motor out of a 2004 Yukon had the long studs in it so I was unable to use. Don't plan on returning as I have already opened the box, so they will sit for my next project or be sold on Market Place. Just take note, if you have a 2004 engine pull it apart before ordering to verify stud length.

The studs were great quality came with nice sockets and everything we will definitely be using them again at our shop

They have very good quality and arrived very quickly. I am super happy.

easy to install if not dumb like me, should have been a walk in the park watched vids and got her done.

Very high quality and are on par to th ARP bolts I looking at.

I have not had a chance to install yet as I am still assembling the motor. However I was extremely pleased with the fast shipping and neatness of the packing. Very professional

Looks good, have not used it yet.

Great product , great quality, fast shipping!

Worked as expected

Great shipping and packaging looks like a great product have not been able to install yet

They went in and seem to be working great the only thing I noticed was in the instructions there were a couple of repeated numbers

smaller m8 bolts on exhaust side of head make clearance issues for exhaust manifold gaskets. Also, if block isn't bottom tapped, the studs hit bottom of rocker arm assemblies.

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.
