Xotic PerformanceCP878 Head Replacement Kit Compatible for 1989-1998 Dodge Cummins 5.9L Diesel 12V, Cylinder Heads with Studs and Nuts, Heavy Duty Cylinder Head Stud Assembly Kit

The media could not be loaded.  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!

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

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!!

I boost 65 here and there 50psi religiously hold up fine

For what they are, this is a great value over buying arp head studs. They have held up perfectly to 50psi

This is the second set of these studs I have installed, they are good quality for a good price I definitely recommend

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.

Good quality if I didn't know any better I'd say it was a arp kit in another box.

I won’t get into details but I will say unequivocally that the manufacturer stands behind their product and it is a pleasure to see a company like this on the market.27 years RSE Mechanic

Kit looks to be good but for my part, one of the nut had bad thread. Trying to reach the supplyer to see what they can do about it.
