Head Stud Replacement Kit for 2004+ Chevrolet Gen III IV LS 4.8L - 6.2L Small Block Cylinder (Primary Head Bolt Lengths Must All be The Same Length) - Xotic Performance™ CP883

Used on my 2012 ls3 perfect , would Reccomend to anyone

I mean, it appears in every way to be ARP quality. The packaging , the quality looks great....time will tell , but so far I am impressed and will likely use them again.

Completely wrong studs. They won't even screw into the stock thread location if they where the right length. I didn't realize this until I went to put a head on so there goes $180

Sockets in kit dont fit nuts, rounded one of the nuts torquing it. A 3/8 twelve point and 5/8 twelve point seemed to fit best.

Great insurance for the mild builds I’m going with on several of my ls engines and also in 6.7l Cummins

Xotic is a good brand with a good reputation because they always deliver. My boyfriend prefers it above any others and said this kit is perfect, makes life much easier and is well worth the cost. Also that is a good fit/compatible as stated and easy to use

Wow! This head stud kit is impressive. Super impressive. When you pick it up for the first time, you’re going to be pretty shocked by how heavy this kit is. I put it on my scale and this little box of bolts weighs 6 pounds!With the provided lubricant, the studs screwed/threaded into the block with surprisingly little effort. Furthermore, when tightening everything down with a torque wrench, these studs feel solid as a rock. I simply can’t imagine there ever being some sort of issue or failure due to this stud kit. It definitely seems like a bulletproof kit to me.If you’re looking for a premium quality stud kit, I think you will have a very hard time finding a better kit. And, in fact, I am pretty certain that a better kit is nonexistent. So, if you can make peace with the price of this kit, I am extremely confident that you will be happy with it.If you have any questions about this Xotic head stud kit, please feel free to ask, and I'll try my best to answer. I hope you found this review helpful.

Head stud was missing threads on one end, entirely smooth. Also, the hex key they include to install the studs into the block very obviously does not fit. Idk how you ship out a set of studs with a hex key and a stud that are all wrong. I probably wouldnt buy these again.
