~(18 lbs. 36X6X6)~ Cummins 89-18 Stage 1 (Steel) 178/208 at .050in .310/.320 108LSA * towing. fuel economy and low end torque. Must run steel tappets and machine block for cam bushing.

The Hamilton Cams 178/208 Steel Camshaft is designed for 1989-2018 Dodge RAM Cummins 5.9L and 6.7L engines, offering enhanced performance at lower RPMs. This camshaft is ideal for drivers seeking improved towing capability, better fuel efficiency, and quicker turbo spool, especially at high altitudes and under heavy loads. It offers an RPM Range of Idle to 4,000 RPM, optimizing low-end performance and early turbo spool, and lowers exhaust gas temperatures by 200-300 degrees. Made of steel construction, it requires steel tappets and block machining for cam bushings; zinc additive recommended. It also features a bolt-on cam gear retainer, pre-drilled and tapped for easy installation. For 12v engines, no more than .020″ piston protrusion and at least .055″ valve face depth with a standard head gasket and a 99 intake centerline is required. For 24v engines, no more than .020″ piston protrusion and at least .038″ valve face depth with a standard gasket is required. If minimum requirements for piston to valve clearance are not met, an oversize head gasket or cut valve reliefs can be used. It is important to check clearances, and new lifters are always recommended when changing a cam.
