If you want your RZR Pro R to make reliable big power, reinforcing the cylinder heads is a must. Avoid premature head gasket wear or failure with EVP ARP Head Stud Kits that offer significantly improved clamp loads, and proper alignment of the head and gasket for more consistent/accurate torque loading. Whether you opt for the ARP 2000 or Custom-Aged 625+ alloy, both are designed to mimic the OEM design but with more thread engagement for a seamless direct replacement that delivers far superior durability.
ARP 2000 FEATURES:
- ARP 2000: Strength-tested to 220,000 psi.
- Made in the U.S.A.
- Constructed from forged and heat-treated ARP 2000 material
- Additional thread engagement compared to other studs
- Mimics OEM design with significantly improved overall strength and durability
CUSTOM-AGED 625+ FEATURES:
- Strength-tested to a minimum of 260,000 psi.
- Made in the U.S.A.
- Custom-Aged 625+ super alloy has superior fatigue cycle life, tensile strength and toughness (comparison: typical 8470 chromoly stud is roughly 170,000 psi.)
- thread-rolled after heat treating to provide optimum fatigue strength
- Additional thread engagement compared to other studs
- Mimics OEM design with significantly improved overall strength and durability

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!

I have had such a great experience with EVO over the course of a year, I wouldn’t even try going anywhere else. Prices are fair and the performance you receive is unreal!!
