3/8in x 1.600 ARP 8740 Rod Bolt

The 3/8in x 1.600 ARP 8740 Rod Bolt is designed for high-performance engine builders and mechanics who require reliable fastener integrity in demanding applications. Rod bolts are essential components that secure the connecting rod to the crankshaft journal, effectively transmitting combustion forces and loads. This product is particularly suited for medium-displacement and larger engine builds that operate under high RPM and boost conditions.

Constructed from ARP 8740 chromoly steel, this rod bolt offers enhanced tensile strength and fatigue resistance compared to standard fasteners. Its 3/8-inch diameter and 1.600-inch length are optimized for applications requiring robust clamping force. The manufacturing process ensures consistent preload characteristics and concentricity, which are vital for preventing rod knock and engine failure.

This fastener is ideal for various engine types, including small-block and mid-sized applications, making it a popular choice for street rods, LS conversions, and import performance builds. By selecting the correct rod bolt, builders can enhance engine longevity and reliability, especially in performance-oriented setups.
