Product Details

The ARP 142-5401 main cap fastener kit is engineered to eliminate main cap walk and fretting while protecting engine block threads in high-performance and competition applications. This 2-bolt main stud kit provides superior clamping force and reliability compared to OEM fasteners.

Key Features:

  • Manufactured from 8740 chrome moly steel for exceptional strength and durability
  • Heat-treated in-house to 200,000 psi tensile strength
  • Precision J-form threads rolled after heat-treat for 1000% stronger threads than conventional fasteners
  • Includes hardened parallel-ground washers and high-quality nuts
  • Designed for 2-bolt main cap configurations
  • Professional-grade quality meeting the exacting standards of engine builders

ARP's post heat-treat thread rolling process creates fasteners with dramatically improved fatigue life compared to bolts threaded before heat-treating. The precision manufacturing and premium materials ensure consistent clamping loads and long-term reliability in demanding racing and performance engine builds.
