ARP (Automotive Racing Products) makes the strongest fasteners in motorsport — head studs, main studs, rod bolts, and flexplate bolts used by every Formula 1, NHRA, NASCAR, and championship motorsport program. Aerospace-grade alloys, exact-fit machining.
The main caps are the foundation of your engine's rotating assembly. When building a Mopar Small Block or B/RB-Series engine, using inferior main bolts is a risk you cannot afford. This Auto Racing Products (ARP) main bolt kit is designed for 2-bolt main applications, providing the clamping force necessary to keep your crankshaft stable under high-load conditions. Manufactured from 8740 chromoly steel, these bolts are heat-treated to ensure they handle the stresses of high-performance street or racing use.
Unlike standard factory bolts, ARP fasteners are designed for repeated use and consistent torque readings. The included hex nuts are precision-machined to ensure even distribution of clamping force across the main cap, which is critical for maintaining proper bearing clearance. Whether you are performing a stock rebuild or a high-performance upgrade, this kit provides the foundation your engine needs to survive the toughest conditions. Don't compromise on the heart of your engine; choose the industry-standard for strength and reliability. Find all your essential engine build components at GGCRACING.
