An ARP main stud kit that upgrades the main bearing cap fasteners on the 900cc/1000cc RZR engine for a stronger, more stable bottom end under high load. ARP studs deliver more uniform clamping than the factory bolts, helping preserve main-bore alignment in built motors. A proven foundation for high-horsepower and forced-induction builds.
