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 2011-2012 Ford Mustang GT and Boss 302 introduced the world to the legendary Coyote 5.0L engine. To ensure these engines perform reliably under increased load, the ARP 256-4702 Head Stud Kit is the preferred choice for enthusiasts. These studs provide a significant upgrade over factory head bolts, ensuring that your cylinder heads remain securely fastened regardless of the power output.
Whether you are adding a cold air intake, headers, or a full supercharger system, your engine needs the stability that only ARP hardware can provide. These studs are heat-treated to ensure maximum strength and are finished with a black oxide coating to prevent corrosion. By upgrading your head studs, you create a more stable environment for your engine, allowing for more aggressive timing and higher boost levels. This kit is essential for anyone looking to unlock the full potential of their early-model Coyote engine. Don't settle for factory hardware when you can have the peace of mind that comes with industry-leading performance parts. For the best selection of engine hardware for your Mustang, visit GGCRACING.
