Hamilton Cams

Extreme Duty Pushrods 07-P-004

These 12mm Hamilton Cams Extreme Duty Pushrods bring unmatched strength to your 24-valve Cummins valvetrain. Designed for 1998.5–2018 5.9L and 6.7L engines, each pushrod features a stout 3-piece construction and thick wall design that pushes the limits far beyond OEM capability. With a buckling strength of up to 6,600 pounds, they outperform stock pushrods, which typically tap out around 1,780 pounds, by a massive margin. This added strength ensures consistent valve lift, better cam timing accuracy, and overall engine stability under high cylinder pressures. Whether your build is geared for competition or heavy street use, these pushrods are a smart upgrade for any high-output application. The increased rigidity reduces the risk of valve train deflection, a common issue when boost and tuning push performance beyond factory tolerances. They are a cost-effective way to reinforce the heart of your engine with race-tested durability. Reliable, precise, and built to last, these pushrods are ready for whatever you throw at them.
