Replacement Rod Bolt Kit 5/16 (8)

The Replacement Rod Bolt Kit 5/16 (8) from ARP is designed for builders and engine shops engaged in serious internal modifications on performance and racing engines. Rod bolts are essential fasteners that secure connecting rods to the crankshaft, and they are among the first components to fail under high horsepower and elevated RPM conditions. This eight-piece kit provides reliable, high-strength fasteners for rebuilding after catastrophic failure or upgrading to heavier-duty internals.

ARP rod bolts are manufactured from premium alloy steel and heat-treated to exacting specifications, ensuring superior clamping force and fatigue resistance compared to OEM fasteners. The 5/16-inch diameter is a common specification across small-block engines, making this kit versatile for various applications. Precise engineering geometry helps distribute stress evenly, reducing the risk of stretch, yielding, or premature failure under sustained load cycles.

This replacement kit is ideal for engine builders, automotive shops, drag racing teams, and street performance enthusiasts who are rebuilding lower-end assemblies. Whether addressing a blown engine or upgrading stock fasteners, this kit ensures maximum reliability during engine assembly. Its design and materials make it suitable for a wide range of performance applications.
