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 Cummins 5.9L diesel engine is legendary for its torque and durability, but the harmonic balancer must be properly secured to handle the massive rotational forces involved. The ARP Dodge Cummins 5.9L Balancer Bolt Kit is designed to replace the factory bolt with a high-strength, heat-treated chromoly steel alternative. This upgrade ensures that your harmonic balancer remains firmly attached to the crankshaft, preventing vibration and protecting your engine's internal components.
For diesel enthusiasts who have added performance tuners, larger injectors, or upgraded turbos, the stock balancer bolt can become a weak point. The ARP bolt provides the extra margin of safety required for high-horsepower Cummins builds. Its superior material properties and precise thread engagement mean you can torque it down with confidence, knowing it will hold up under the most demanding conditions. Whether you are towing heavy loads or competing on the track, this bolt kit is a simple yet vital insurance policy for your engine. Upgrade your diesel performance hardware today at GGCRACING.
