ARP SB Chevy 4-Bolt Large Journal Main Bolt Kit

ARP is well-known for making strong fasteners, and this main bolt kit for Small Block Chevy engines with 4-bolt large journal main caps is no exception. If you're rebuilding the bottom end of your engine, especially if it's a performance build, these bolts are a solid choice to secure your crankshaft.

This kit uses high-strength ARP 2000 material, which offers improved tensile strength over standard Grade 8 bolts. This means they can handle the increased clamping forces and stresses found in performance applications. The bolts are also black oxide coated for some corrosion resistance. They are designed to be a direct replacement for your stock main bolts, making installation straightforward as long as you have the proper torque wrench and follow the manufacturer's recommended torque sequence and lubrication procedures.
