This ARP main bolt kit replaces the two-bolt large journal main bolts on small block Chevy engines. Supplied as a direct replacement set, these bolts are intended for builders restoring bearing caps to factory-style clamping geometry. Use this kit when reassembling an SB Chevy block where OE-style two-bolt mains are required to secure crank bearing caps.
