Prevent premature head gasket failure on bigger power engines! The Evolution Powersports' XR Series CA-625 10mm head studs are for those wanting the ultimate strength for 350-450 horsepower engines. Designed by EVP and manufactured by ARP using their proprietary Custom Age alloy, we have developed the strongest 10mm stud available anywhere. 

Custom Age 625 alloy typically equals or exceeds the clamping force of ~2mm larger 8470 Chromoly fastener in a smaller package. When installed in Can Am X3 engine where there is not much material in the block to enlarge the stud significantly, the 10mm Custom Age 625 is the ideal solution. These head studs will keep your engines head sealed for the boost pressure required to produce 350-450 horsepower.

*NOTE: Requires block to be machined

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

Evolution Powersports has a reputation of the utmost quality and attention to detail on every product they design. From within the industry and outside, I have heard nothing but great things about this company and my experience has been the same. If you are looking to make more reliable power this company can get you there. Both customer service and product design are top notch and they stand behind their work!

If you truly want to build your project with the best possible parts available, buy EVO. They not only build with the best materials they test and test to make sure you are getting the performance gains they say you will but that the mods will be safe and keep the reliability of the machine as high as possible. Thanks again to both Jim and Todd. Keep it up guys!
