Head Stud Kit 2017-2025 For 6.6L L5P Chevrolet GMC Duramax

Amazing customer service

The customer service department warrantied a whole brand new set of head studs bc the head of one bolt twisted off. They must’ve shipped them next day air bc I filed a claim on Friday afternoon after speaking to a nice lady and the new studs were in my hand Sunday morning. You won’t find any better people that stand behind their product.

2018 L5P head studd

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.
