Hamilton Cams Extreme Duty Pushrods 07-P-004 | 1998.5-2018 CUMMINS 5.9L/6.7L

The Hamilton Cams 07-P-004 Extreme Duty Pushrods are engineered for high-performance Dodge Ram 5.9L and 6.7L Cummins diesel engines producing over 500 horsepower. Increased cylinder pressure in modified diesel engines can cause factory pushrods to flex, bend, or buckle, which may lead to inaccurate valve timing and reduced engine reliability. These heavy-duty pushrods are designed to provide the strength and stability required to maintain consistent valvetrain operation under demanding conditions.

Constructed with a robust three-piece design, the Hamilton Extreme Duty Pushrods feature a large 12mm diameter and a thick .120-inch wall. This upgraded construction significantly increases rigidity compared to factory 3/8-inch pushrods or typical 7/16-inch performance alternatives. The added strength minimizes deflection during high load conditions, helping maintain precise valve lift and accurate camshaft timing.

With an impressive buckling strength of up to 6,600 lbs—far exceeding the approximate 1,780 lb rating of OEM pushrods—these pushrods are built to withstand the extreme cylinder pressures common in heavily modified Cummins engines. Hamilton pushrods have been tested in engines producing over 3,000 horsepower, demonstrating the durability required for both high-performance street applications and dedicated race builds.
