2003-2018 Cummins 5.9L/6.7L 24V Hamilton Cams Extreme Duty Pushrods 12MM (07-P-004)
Looking to overcome the bending, buckling, and cam timing issues caused by high cylinder pressures in engines over 500 horsepower? Our heavy-duty pushrods are designed to solve that problem. Featuring a 3-piece design with a robust 12mm diameter and .120″ wall thickness, these pushrods are significantly stronger than OEM 3/8″ or standard performance 7/16″ options.
Why Choose Our Pushrods?
- Engineered for Power: Tested in builds exceeding 3,000 horsepower, ensuring reliable performance at extreme power levels.
- Superior Strength: With a buckling strength of up to 6,600 lbs (compared to OEM pushrods at 1,780 lbs), you’ll get consistent valve lift and avoid retarded cam timing.
- Precision & Reliability: Thicker walls and a larger diameter provide improved stability under intense cylinder pressures, reducing the risk of deflection.
- Great Value: Get race-ready quality at an affordable price point—perfect for both mild performance upgrades and full-blown race engines.
