ARP Polaris 900cc / 1000cc RZR Main Stud Kit

This is the ARP Main Stud Kit for your Polaris 900cc or 1000cc RZR engine. When you're pushing your RZR hard, especially with performance modifications, the main bearing caps need to stay exactly where they are. These studs replace the weaker factory bolts, providing a much more secure clamping force on your crankshaft and main bearings. This is crucial for preventing bearing walk and maintaining proper oil clearances under high load and RPMs.

ARP uses high-strength 8740 chromoly steel for these studs, heat-treated to a nominal tensile strength of 200,000 psi. They are centerless ground for a perfect concentricity and then thread rolled to ensure maximum thread strength. The kit includes the necessary studs, nuts, and washers, all manufactured to ARP's exacting standards. Installing these studs is a smart move if you're rebuilding or significantly upgrading your RZR's engine, ensuring the foundation of your build is solid.
