Important Fitment Notice

• If you’ve had your engine block or cylinder head surfaced, please call us for verification to ensure proper kit fitment.
• Intake Valve Lash: 0.010″
• Exhaust Valve Lash: 0.020″

Oil Recommendations

• For warm weather: Use Valvoline Premium Blue 15W-40
• For cold climates: Use Valvoline 5W-40
• Alternatively, Schaeffer 700 Series is also an excellent choice.

The Hamilton Cams Difference

“Innovation slightly faster than imitation.”
We’ve earned this reputation by investing in the research, engineering, and quality manufacturing that others attempt to copy.

Forged Steel Camshafts

• Tighter Grain Structure: Our 178-208 steel cams are forged, not cut from bar stock—resulting in a denser, more uniform grain structure.
• Enhanced Longevity: A natural “halo” forms on the exterior of the cam during forging, adding a layer of strength for extended service life.

DLC-Coated Tappets

• Gas Carburized & Polished: Each tappet undergoes a meticulous hardening process, then is polished for a smoother contact surface.
• Diamond-Like Carbon (DLC) Coating: This ultra-hard surface finish dramatically reduces friction and wear—if a tappet isn’t DLC-coated, you’re missing out on the best protection available.

Heavy-Duty Pushrods

• 3500+ lbs Buckling Force: Compared to around 1800 lbs for OEM pushrods, ours drastically reduce deflection at high cylinder pressures.
• Consistent Valve Timing: With less flex, your valvetrain stays precisely in sync—even under extreme conditions.

Upgraded Rocker Arms

• High-Quality Casting: Built to handle intense stress and heat cycles.
• Gas Carburized Ball & Foot: Reduces friction and wear for longer service intervals.
• DLC-Coated Trunnion: Minimizes galling—an all-too-common issue with OEM trunnions—and lowers overall friction in the valvetrain.

Proven Performance & Reliability

• Decades of Experience: Our cams have powered countless diesel engines for millions of road miles and thousands of dyno runs.
• SEMA-Certified (49-State Compliance): This kit is tested and certified for street use in 49 states, giving you peace of mind.

When you choose Hamilton Cams, you’re investing in proven innovation and superior craftsmanship. Experience the confidence that comes from a kit designed to hold up under extreme conditions, and help your Cummins engine deliver reliable power for the long haul.
