ARP (Automotive Racing Products) is widely recognized as the world leader in high-strength fasteners for performance, racing, and engine-building applications. Since 1968, ARP has set the industry benchmark for precision metallurgy, uncompromising material quality, and exacting manufacturing standards, supplying engine builders, professional race teams, and serious enthusiasts with the most reliable fasteners on the market.
ARP’s reputation is built on purpose-engineered hardware designed to withstand the extreme stress, heat, and vibration found in high-performance engines. Every ARP fastener begins with premium, U.S.-sourced materials—including ARP2000, Inconel 718, Custom Age 625+, and stainless alloys—each selected for superior tensile strength and fatigue resistance. Unlike generic hardware, ARP fasteners are cold-forged, heat-treated, centerless-ground, and thread-rolled after heat-treat, a sequence that maximizes grain structure and produces unmatched durability under load.
From main stud kits, rod bolts, head studs, balancer bolts, and cam fasteners to specialty kits for the latest domestic and import platforms, ARP continues to expand its lineup with solutions for Chevrolet, Ford, Mopar, LS, LT, Hemi, Godzilla, Coyote, Duramax, and today’s emerging modern engines. Their offerings also include fastener assortments for Toyota/BMW B58, Dart 2JZ applications, Brodix blocks, and countless custom builds across the racing landscape.
Every ARP component is engineered, tested, and manufactured in-house in the USA, ensuring tight quality control and the kind of repeatable accuracy engine builders depend on. With torque values backed by real data, complete application notes, and exact specifications, ARP gives builders confidence that every critical joint in the engine is secured with hardware capable of handling extreme horsepower.
Whether you’re assembling a mild street cruiser or a 2,000+ HP competition engine, ARP delivers the strength, precision, and reliability that protect your investment and unlock maximum performance. ARP fasteners aren’t just hardware—they’re a foundational element of any serious build.
