Replacement Rod Bolt Kit 3/8 (2)

The ARP Replacement Rod Bolt Kit 3/8 (Part No. 200-6227) is a professional-grade connecting rod fastener set engineered for high-performance engine builds. This pair of 3/8-inch bolts measures 1.5 inches in length and is manufactured from ARP2000 chromoly material in natural finish, designed for universal fit with steel rod applications. Rod bolts are critical fastening components that secure the connecting rod to the crankshaft, and ARP's Pro Series bolts are engineered to withstand extreme clamping loads and cyclic stress in demanding engine environments.

ARP2000 material delivers superior tensile strength compared to standard fasteners, providing consistent clamping force across thermal cycles and high-RPM operation. The 3/8-inch diameter and 1.5-inch length specification ensure proper load distribution through the connecting rod cap while maintaining compatibility with standard rod bore sizing. Natural finish bolts require proper lubrication during installation to achieve accurate preload values, critical for engine longevity and reliability. This kit ships as a pair, making it suitable for single-rod replacement or as a refresher set during engine rebuild procedures.

Rod bolt replacement is essential during any full engine rebuild, particularly in performance or marine applications where connecting rods experience elevated stress. Technicians and engine builders rely on ARP fasteners for their consistent quality and precise dimensional tolerances. Whether you're rebuilding a street engine, race motor, or addressing crankshaft damage, matching bolt specifications to your connecting rod design is non-negotiable for reliability. Stock these replacement bolts when planning a major engine overhaul to avoid delays and ensure your build meets specification from assembly to first fire.
