Description
Why the EVP XR Series CA-625 studs are superior to other studs on the market:
- The 10mm OD is the ideal size to maximize clamping force without sacrificing block integrity
- Made from ARP CA625 alloy - This super-alloy has superior fatigue cycle life, tensile strength and toughness and is rated to 260,000 psi tensile strength. For comparison, a typical 8470 chromoly stud is roughly 170,000 psi.
- More thread engagement into the engine block compared to other studs.
- Machined ball end allows the stud to bottom out in the case without losing any thread engagement.
- Includes head studs, nuts, and washers for the ultimate high horsepower head stud kit
*NOTE: Requires block to be machined
