About ARP

ARP (Automotive Racing Products) makes the strongest fasteners in motorsport — head studs, main studs, rod bolts, and flexplate bolts used by every Formula 1, NHRA, NASCAR, and championship motorsport program. Aerospace-grade alloys, exact-fit machining.

Watch in action

Ultimate Engine Reliability for Polaris RZR

When pushing your Polaris RZR 900cc or 1000cc engine to the limit, stock main bolts often fail to provide the necessary clamping force. The ARP Main Stud Kit is engineered to prevent main cap walk and ensure your engine block remains rigid under extreme boost or high-RPM conditions. Crafted from premium 8740 chromoly steel, these studs offer superior tensile strength compared to OEM hardware.

Key Features and Benefits

  • Constructed from high-tensile 8740 chromoly steel for maximum durability
  • Precision-rolled threads for optimal clamping force and fatigue resistance
  • Prevents main cap movement during high-performance operation
  • Includes high-quality nuts and hardened washers for a complete installation
  • Direct fitment for Polaris RZR 900cc and 1000cc engine platforms

Whether you are building a race-spec engine or a high-performance trail machine, these studs provide the peace of mind required for aggressive driving. The kit ensures that your engine internals stay perfectly aligned, reducing the risk of catastrophic failure. Trust in the industry-leading quality of ARP engineering to keep your engine together when it matters most. Find all your high-performance engine hardware at GGCRACING.
