Product Description
The ARP 247-6303 Pro Series Rod Bolt Kit is designed for 1989-2002 Dodge Ram 5.9L Cummins engines equipped with steel angled cap connecting rods. Built from premium ARP2000 alloy, these fasteners deliver superior clamping force and fatigue resistance compared to factory rod bolts, making them ideal for towing, performance, and high-cylinder-pressure diesel applications.
ARP Pro Series rod bolts are precision CNC-machined, heat-treated, and thread-rolled after heat treatment to improve fatigue life and durability. These bolts are commonly used in engine rebuilds and high-performance Cummins builds where rotating assembly reliability is critical.

WHY UPGRADE TO ARP PRO SERIES ROD BOLTS?
Connecting rod bolts experience extreme cyclic loading in diesel engines under heavy towing, elevated boost, higher RPM, and increased fueling conditions. ARP Pro Series rod bolts provide significantly greater fatigue resistance and clamping strength than stock hardware, helping improve long-term rotating assembly durability.

Good insurance
I have used ARP Products in many engine builds. It gives me confidence of not having a parts failure due to weak hardware.
