Review on ARP 129-2503 Dampener Bolt for Enhanced Performance in GM Durmax Engines by Justin Cage

Revainrating 5 out of 5

Quality clasp 36mm

This is ARP, the quality is as expected. I'm just writing this review to let people know that after my purchase in November 2020 they are now shipping an updated part number that includes a 36mm 12pt head, exactly the same as the factory bolt.

Pros
  • Country of origin: USA
Cons
  • No instructions
