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.
Properly securing your harmonic balancer is essential for engine health. The Auto Racing Products Harmonic Balancer Bolt is designed to provide maximum security for Big and Small Block Ford engines. Featuring a robust 1-1/8 inch hex head with an integrated 1/2-inch square drive, this bolt makes installation and removal straightforward, even in cramped engine compartments.
Constructed from heat-treated chromoly, this bolt is designed to handle the intense harmonic vibrations and rotational forces generated by high-performance engines. By replacing your stock hardware with this high-tensile bolt, you reduce the risk of balancer failure, which can lead to catastrophic engine damage. The black oxide coating ensures that the fastener remains protected against corrosion, maintaining its integrity over years of use. This is a must-have component for any serious engine build, providing peace of mind whether you are on the street or the drag strip. Trust the experts at GGCRACING to provide the high-quality fasteners your vehicle deserves.
