Built Stronger So You Can Push Harder

If you're building power with your 24-valve Cummins, your rocker arms are one of those parts you can't afford to overlook. The Hamilton Cams 07-R-003 rocker arms give you a serious durability upgrade over stock without blowing the budget. Whether you're chasing more boost, more RPM, or just more reliability, these rocker arms are made to handle it. They're built using an improved casting process for added strength and longevity, so you can drive harder without worrying about valvetrain failure. Unlike some factory models that used plastic retainers, these feature swaged steel tips for a longer service life and more consistent performance. They're also a smart move for daily drivers running mild upgrades who want OEM-style fitment with better materials. If you’re looking for a dependable, affordable upgrade that can grow with your build, this is the kind of bolt-on peace of mind every Cummins owner should consider.

Designed For High Load And Long Life Performance

Hamilton’s 07-R-003 high performance rocker arms are engineered for 1998.5-2018 5.9L and 6.7L Cummins engines, offering critical improvements in strength, wear resistance, and oil control. Each arm uses a refined casting that’s stronger than OEM designs, making it suitable for everything from high-torque street setups to 3,000 horsepower competition builds. The trunnions are DLC-coated, which significantly reduces friction at the pivot point and improves longevity under extreme stress. Better oiling throughout the rocker body helps prevent galling and reduces the chance of heat-related damage during extended high-load operation. Instead of plastic retainers found on certain factory rockers, these arms are equipped with swaged steel tips that provide a more stable and reliable contact point. Despite these upgrades, they retain an OEM-style profile, making them an easy fit for most street or race-oriented valvetrain builds. They also come at a lower cost than factory replacements, giving builders an edge in both performance and value.
