Wake up your 1989-1998 Dodge 5.9L Cummins with the Hamilton Cams 12 Valve Cam Package, available in two options: the 178/208 camshaft package or the 188/220 camshaft package. Whether you're after efficiency, improved power, or all-around performance, Hamilton Cams delivers solutions to meet your needs. Both packages include: heavy duty pushrods, 165 lb. valve springs, and a set of lifters/tappets. NOTE: DOES NOT COME WITH RETAINERS AND LOCKS.

Designed for optimal efficiency and throttle response, this package is perfect for those seeking improved low-RPM performance and quicker spool up. It’s ideal for daily drivers looking for maximum efficiency and is great at high altitudes.

For trucks pushing performance boundaries, the 188/220 Camshaft Package offers enhanced power across the RPM range, making it ideal for stock-class pulling, drag racing, or high-performance builds.

• Both cam options are considered “drop-in,” requiring no more than .020” piston protrusion and at least .055” valve face depth with a standard head gasket. If these clearances aren't met, oversized head gaskets or valve reliefs may be required.
• Apply a liberal amount of high-quality assembly lube to cam lobes and journals.
• Prime the oil pump and oil filter before starting.
• Verify oil pressure before engine start-up.
• Run the engine at 1200-1500 RPM for 5 minutes, then shut it down.
• Adjust valve lash after each torque sequence to account for gasket compression.

Whether you choose the 178/208 package for efficiency or the 188/220 package for power, both deliver Hamilton Cams' signature quality and performance, ensuring your 12V Cummins is ready for any challenge.
