ARP 132-5402 Main Cap Fasteners Main Stud Kit - 2-Bolt

The ARP 132-5402 is a high-performance main stud kit designed for 2-bolt main engine applications. This complete fastener system eliminates main cap walk and fretting while protecting the threads in your engine block, ensuring superior clamping force and reliability in demanding applications.

Key Features:

• Manufactured from premium 8740 chrome moly steel for exceptional strength and durability
• Heat-treated in-house to 200,000 psi tensile strength for maximum clamping performance
• Precision J-form threads rolled after heat-treat process for 1000% stronger threads than conventional fasteners
• Complete kit includes hardened parallel-ground washers and high-quality nuts
• Rolled threads provide superior fatigue resistance compared to cut threads
• Engineered to meet professional engine builder standards

ARP main studs are the preferred choice for competition engines and high-performance builds where reliability and precision matter. The post-heat-treat thread rolling process creates fasteners with significantly extended fatigue life, while the parallel-ground washers ensure even load distribution across the main caps. This kit provides the ultimate insurance against main cap movement and maintains critical bearing clearances under extreme loads.
