This cylinder head rebuild kit is rated at 220,000 psi tensile strength. Threads rolled after heat treatment for optimum fatigue strength. Ample clamping strength prevents cylinder heads from lifting.

I’ve used these studs before with no issue. The problem I’m having is that it has been almost 3 months and they are still processing a refund on then sending 24 valve studs when I ordered 12 clave studs

I boost 65 here and there 50psi religiously hold up fine
rock jock –
For what they are, this is a great value over buying arp head studs. They have held up perfectly to 50psi

This is a high quality set of head studs. If you’ve priced different brands, then you know that prices range from $60 to over $500. This set is comfortably in the middle, although they are top quality. Also, they were eligible for free Prime shipping so I had them in 2 days.

Open box review, good packaging and great instructions! Will update this review in 1 year after putting the studs thru the paces!
Well I’ve put about 4k miles on em running 45psi of boost with a he351 with a fel pro head gasket and they work!

Installed on a 95 12 valve . no problems holding good with compounds and 40 psi of boost. Instructions could be ALOT better, no mention of milling the rocker pedestals, nothing about three torque steps. I had to Google ARP’s Instructions to get the milling specs and three diff steps of torque, i used Xotic’s final torque number, but hey much cheaper than ARP!!

Good affordable head studs for my 5.9, 12 valve Cummins. They come nicely packaged.

I’m gonna make this short and sweet. First install one stud broke. Being a Red Seal I’m trained to do it right and not overlook issues some would so I pulled the head and reinstalled new gasket and new stuff kit from these guys. Three months later I’m building confidence and then…. THREE STUDS BROKEN BY THE COOLANT PUMP! 130lbs in succession over three stages and still these crap studs broke.
If you’re reading this XOTIC, you owe me new studs and I’m holding you to your promise of guarantee. Furthermore I’m having the studs tested and sharing my experience with my 250K Subs on You Tube. Expect an invoice XOTIC
