Product Details

The ARP 124-5402 main stud kit delivers professional-grade engine block reinforcement for high-performance and racing applications. Engineered to eliminate main cap walk and fretting while protecting engine block threads, this 2-bolt main stud kit provides the reliability demanded by serious engine builders.

Key Features:

  • Constructed from 8740 chrome moly steel for exceptional strength and durability
  • Heat-treated in-house to 200,000 psi tensile strength for maximum clamping force
  • Precision J-form threads rolled after heat-treatment for 1000% stronger threads than conventional fasteners
  • Includes hardened parallel-ground washers and high-quality nuts for complete installation
  • Rolled threads provide superior fatigue life compared to cut threads
  • Designed for 2-bolt main cap engine blocks

ARP's proprietary heat-treating process and post-heat-treat thread rolling creates fasteners with dramatically improved fatigue resistance and thread strength. The included parallel-ground washers ensure even load distribution across the main cap surface, while the premium nuts provide consistent torque values during installation. This complete kit provides everything needed to secure main caps with confidence in demanding performance applications.
