Ready to talk about some valvetrain upgrades for your Cummins? Look no further than Hamilton Cams. From Pushrods, to Camshafts, to Tappets, we have you covered to get your Cummins valvetrain built up to handle those insane boost pressures and make that all mighty horsepower goal you are after!
Camshaft Selection; All Parts fit 1998.5 to 2018 Cummins!
178/208 Camshaft: Great for Towing Heavy & Best Efficiency/Power Balance for Highway Driving. Great choice for moderate street truck builds. This is good for applications NOT looking at high RPM power.
188/220 Camshaft: Idle to 4200 RPM; Advertised as “Largest Drop In” Cam from Hamilton; Great choice for larger singles & compounds. Good for the Upper Realm of HP.
When installing these camshafts, ensure you properly check for piston to valve clearance! These descriptions are from the manufacturer, however due to all the variables in engine building, clearance is not guaranteed!
1.45″ Tappets: Normally changed out whenever a new camshaft is installed. Requires removal of engine & disassembly to install. Advertised as “Lighter” than CR Stock Tappets
1.45″ Billet Steel Tappets: ONLY USED FOR BILLET STEEL CAM or over 5000 RPM on a normal basis.
103 Springs: Used for mostly street applications over 50 PSI of Boost and exceeding 3800 RPM regularly. Sold as a complete set. Retainers are NOT included.
