ARP's main stud kit reinforces the bottom end of your Polaris RZR 900 or 1000, eliminating main cap walk and fretting while protecting the threads in the block. For built and boosted engines, it's the foundation that keeps the crankshaft properly located under load.
Each kit comes complete with hardened, parallel-ground washers and high-quality nuts for precise, repeatable torque. A must-have upgrade for RZR engines pushing beyond stock power.
