Hamilton Cams Steel Pushrod for Cummins 5.9L 6.7L

Description

Product Overview

The Hamilton Cams Heavy Duty Steel Pushrod is a purpose‑built component for Cummins 5.9L and 6.7L diesel engines produced between 1998.5 and 2017. Manufactured in the United States, each pushrod measures 3/8‑inch in diameter with a robust .095‑inch wall thickness, delivering the structural integrity required for engines generating 500 to 750 horsepower. The part number 07‑P‑003 (also listed as HCPR‑1000H) replaces OEM rods and is compatible with both intake and exhaust applications. Constructed from high‑grade carbon steel, the rods are heat‑treated for optimal tensile strength and resistance to fatigue, ensuring consistent valve lift and timing under extreme loads.

Usage

These pushrods excel in heavy‑duty environments where reliability is non‑negotiable. Whether you are rebuilding a fleet truck, upgrading a performance diesel, or maintaining a workhorse engine in a construction vehicle, the Hamilton Cams pushrods provide the confidence that the valve train will operate smoothly. They are suited for daily high‑load operation, off‑road conditions, and high‑rpm scenarios typical of performance builds. Installation requires standard tools and follows the factory service manual procedures, making them a straightforward upgrade for professional mechanics and experienced DIY enthusiasts alike.
