Unmatched Durability for Your Dodge Cummins 5.9L Harmonic Balancer

The robust power and immense torque of the Dodge Cummins 5.9L diesel engine, whether 12V or 24V, generate significant vibrations that demand fasteners capable of extreme resilience. The harmonic balancer is a critical component for dampening these vibrations, protecting your crankshaft and other engine accessories. The ARP Harmonic Balancer Bolt Kit (147-2502) provides the ultimate solution for securing your balancer, ensuring engine smoothness and longevity. This kit includes a set of four high-strength chromoly bolts, meticulously engineered with a 12-point head design to ensure superior clamping force and resistance to loosening, even under the most extreme diesel performance applications, heavy-duty towing, and high boost pressures.

Why Choose ARP for Your Cummins Balancer?

• Extreme Strength Chromoly: Each bolt is forged from premium chromoly steel, offering significantly higher tensile strength and fatigue resistance compared to OEM fasteners, which are often inadequate for modified diesel engines.
• Precision Fitment: Designed with a precise 12 mm x 1.25 thread and a 1.425 inch length, perfectly suited for the Dodge Cummins 5.9L 12V and 24V harmonic balancers, ensuring optimal engagement.
• 12-Point Head: The 14 mm 12-point head allows for precise torque application and secure tightening, minimizing the risk of stripping or rounding during installation, a common issue with inferior fasteners.
• Corrosion Protection: A durable black oxide finish provides a protective layer against rust and corrosion, ensuring long-term reliability and performance in demanding engine environments, including exposure to diesel fluids.

Optimize Your Diesel Engine's Performance and Reliability

Prevent costly engine damage and maintain optimal vibration control by upgrading to an ARP Harmonic Balancer Bolt Kit. This essential modification is vital for any Cummins 5.9L owner, especially those running higher horsepower, increased boost, or heavy towing applications where engine stress is maximized.
