Product Details

The ARP 234-5608 Main Cap Stud Kit is engineered for high-performance and competition engines requiring superior main cap retention. This 4-bolt main stud kit eliminates main cap walk and fretting while protecting the threads in your engine block.

Key Features:

  • Manufactured from premium 8740 chrome moly steel for exceptional strength
  • Heat-treated in-house to 200,000 psi tensile strength
  • Precision J-form threads rolled after heat-treat for 1000% greater strength than conventional fasteners
  • Hardened parallel-ground washers included for optimal load distribution
  • High-quality nuts ensure proper clamping force
  • 4-bolt main configuration for maximum main cap stability

ARP main studs provide far superior clamping force compared to OEM bolts, making them essential for engines with increased horsepower, higher cylinder pressures, or those subjected to extreme operating conditions. The post-heat-treat thread rolling process creates fasteners with significantly improved fatigue life and resistance to stress cracking. Professional engine builders trust ARP fasteners to meet the exacting demands of competition applications where failure is not an option.
