Product Details

The ARP 135-5202 Main Stud Kit is specifically engineered for Big Block Chevy engines using WorldProducts Merlin II and Merlin III blocks. These high-performance main studs provide superior clamping force compared to factory bolts, ensuring the main caps remain securely in place under extreme cylinder pressures and loads.

Key Features:

  • Manufactured from ARP's premium 8740 chromoly steel for exceptional strength and durability
  • Heat-treated to 200,000 PSI tensile strength for maximum reliability
  • Precision thread rolling for improved fatigue resistance
  • Black oxide finish for corrosion protection
  • Includes high-quality hardened parallel-ground washers
  • ARP Ultra-Torque assembly lubricant included for accurate torque readings

ARP main studs eliminate the possibility of main cap walk and fretting, making them essential for high-performance and racing applications. The superior thread engagement and even clamping force distribution help prevent cap movement and ensure proper bearing alignment. Each kit is manufactured to exacting tolerances and quality controlled in ARP's California facility.
