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.
For specialized high-performance engine applications requiring a smaller yet incredibly strong fastener, the ARP Pro Series Connecting Rod Bolt Kit (MPN: 200-6210) stands as the definitive choice. This kit includes eight 5/16-inch diameter bolts, precisely 1.5 inches in length, engineered from ARP's superior ARP2000 chromoly material. Designed for universal steel connecting rods, these bolts provide the essential security and reliability for demanding engine environments.
Despite their more compact size, these 5/16-inch ARP Pro Series bolts deliver monumental strength, thanks to the advanced ARP2000 alloy. This material, a heat-treated chromoly steel, offers significantly higher tensile strength and fatigue life compared to standard fasteners, making it perfect for engines where space is at a premium but performance cannot be compromised. The 1.5-inch underhead length is ideal for specific universal steel rod designs.
The connecting rod bolts are among the most stressed fasteners in an engine, making their quality absolutely critical. ARP Pro Series bolts, crafted from ARP2000, are rigorously tested and race-proven to withstand the most extreme forces generated by high RPMs and aggressive power delivery. By choosing ARP, you're not just buying bolts; you're investing in the long-term health and peak performance of your engine, ensuring every component works in harmony.
Equip your engine with the finest fasteners available. Explore our full selection of ARP components at GGCRACING.
