3/8in x 1.600 ARP 2000 Rod Bolt

The 3/8in x 1.600 ARP 2000 Rod Bolt is a crucial fastening component designed for serious engine builders and performance mechanics engaged in high-stress internal modifications. These bolts are engineered specifically for small-block and big-block applications where standard factory hardware may fail under elevated RPM, boost, or nitrous oxide loads.

Constructed from ARP 2000 material, a proprietary alloy, these rod bolts offer superior tensile strength and fatigue life compared to standard OEM fasteners, boasting a tensile rating of 200,000 PSI. The precise thread rolling and hardening processes ensure consistent preload retention, which is vital for maintaining proper rod side clearance and preventing catastrophic bearing wear or journal scoring.

Ideal for endurance racing, street performance, and forced-induction builds, these fasteners are trusted by professional engine shops and independent builders alike. The 3/8-inch diameter and 1.600-inch length specification fit the rod journal geometry of numerous domestic V-8 platforms, providing a reliable upgrade during engine assembly or reconditioning.
