Product Details

The ARP 145-5601 main stud kit provides superior clamping force and reliability for high-performance and competition engines. Engineered to eliminate main cap walk and fretting while protecting engine block threads, this complete fastener solution delivers the strength and precision demanded by professional engine builders.

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
  • Includes hardened parallel-ground washers and high-quality nuts
  • Designed for 4-bolt main applications
  • Generous under-head radius for improved load distribution
  • Rolled threads after heat-treating provide superior fatigue life

ARP's post-heat-treat thread rolling process creates fasteners with dramatically improved fatigue resistance compared to fasteners threaded before heat treatment. The included hardened washers ensure even load distribution, while the precision-ground design guarantees consistent torque values and optimal clamping force. This kit represents a significant upgrade over OEM fasteners for any performance or racing application.
