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.
When building a high-performance Small Block Chevy, engine block integrity starts at the main caps. The Auto Racing Products (ARP) High Performance Main Bolt Kit is engineered to provide superior clamping force compared to OEM fasteners. Designed specifically for 2-bolt main blocks with large journals, this kit ensures your crankshaft remains stabilized under high-load conditions.
Each fastener in this kit is heat-treated and precision-machined to ensure consistent clamping loads, preventing main cap walk and protecting your bearings from premature wear. Whether you are building a street machine or a weekend track warrior, these bolts offer the peace of mind that your bottom end is secure. By choosing ARP, you are investing in the industry standard for engine fastener technology. Trust the experts at GGCRACING to provide the high-performance hardware your engine deserves for long-lasting operation and peak output.
