DESCRIPTION

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.
