Product Description
Hamilton Cams 07-P-004 Extreme Duty 12mm Pushrods for 1998.5–2018 Cummins 5.9L/6.7L 24V
The Hamilton Cams 07-P-004 Extreme Duty 12mm Pushrods are engineered for high-performance 24-valve Cummins engines where factory pushrods are no longer sufficient. Designed for 1998.5-2018 5.9L and 6.7L Cummins applications, these heavy-duty pushrods feature a robust 12mm diameter, .120-inch wall thickness, and a durable 3-piece chromoly construction to withstand extreme cylinder pressures and high-RPM operation. They are commonly recommended for trucks producing over 500 horsepower and have been tested in applications exceeding 3,000 horsepower.
When boost pressure, valve spring pressure, and cylinder pressure increase, factory pushrods can flex or bend, resulting in cam timing retardation and reduced valve lift. The Hamilton 07-P-004 pushrods are designed to eliminate that weakness, providing superior valvetrain stability, more consistent valve motion, and increased durability for towing, street performance, racing, and competition diesel applications.

FAQ
When should I upgrade from factory pushrods?
Hamilton recommends upgrading when boost pressure, cylinder pressure, valve spring pressure, or horsepower levels increase significantly. These pushrods are commonly recommended for applications exceeding 500 horsepower.
Will these fit both 5.9L and 6.7L 24-valve Cummins engines?
Yes. The 07-P-004 pushrods are designed for 1998.5-2018 24-valve Cummins engines, including both 5.9L and 6.7L applications.
Are these only for race trucks?
No. While they are capable of handling extreme horsepower levels, they are also an excellent upgrade for towing, street performance, and daily-driven trucks with increased power levels.
How much stronger are they than stock pushrods?
These 12mm pushrods feature a significantly larger diameter and thicker wall than OEM pushrods, providing dramatically improved resistance to bending and deflection under high cylinder pressures.
Do they work with stock cams and tappets?
Yes. The 07-P-004 pushrods can be used with stock or performance camshafts and are compatible with factory-style valvetrain configurations.
What is included in the kit?
The package includes one matched set of twelve Hamilton Cams Extreme Duty 12mm pushrods.
