Review on ARP 100 7531 Valve Cover Bolt by Josh Dyer

Revainrating 5 out of 5

The only way to get good cover bolts

I've used this bolt kit before. They simplify the installation and removal of Duramax valve covers considerably. The original screws are hex head screws and working with them can be a real challenge. Old screws end up in the trash.

Pros
  • Engine Parts
Cons
  • Interchangeable
