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.
Upgrade your Pontiac V8 harmonic balancer installation with this specialized square drive bolt from Auto Racing Products. This fastener is designed for enthusiasts who demand precision and reliability. Featuring a 5/8-18 thread and a 1/2-inch square drive, this bolt allows for secure tightening and consistent torque, ensuring your balancer remains perfectly aligned with the crankshaft.
The harmonic balancer is essential for dampening engine vibrations. A loose or improperly installed balancer can lead to catastrophic engine failure. This ARP bolt provides the clamping force needed to keep the damper secure under all operating conditions. The combination of a hex head and a square drive offers versatility during installation, making it easier to achieve the correct torque value. Constructed from high-quality chromoly steel and finished with a durable black oxide coating, this bolt is built to last. It is an essential upgrade for any Pontiac engine build, whether for street or strip use. Experience the difference in quality and performance with components from GGCRACING.
