Hamilton Cams 07-CC-12V178 178/208 Camshaft Combo

The Hamilton Cams 07-CC-12V178 178/208 Camshaft Combo is engineered to enhance the performance and efficiency of 1989-1998 Dodge Cummins 5.9L 12-valve engines. This comprehensive kit includes a camshaft, heavy-duty pushrods, 165 lb valve springs, retainers, locks, and lifters/tappets, providing a balanced power curve suitable for towing and daily driving.

Detailed Product Description

178/208 Camshaft

The camshaft features a duration of 178° intake and 208° exhaust at 0.050" lift, optimizing airflow for improved throttle response and efficiency. It operates effectively from idle up to 4,000 RPM, making it ideal for low-end torque and quicker turbo spool-up.

Heavy-Duty Pushrods

Included are heavy-duty pushrods capable of handling power levels from stock up to 2,000 horsepower, ensuring durability under increased engine stresses.

165 lb Valve Springs with Retainers and Locks

The 165 lb valve springs provide enhanced seat pressure to prevent valve float at high RPMs and boost levels. Accompanied by retainers and locks, they ensure secure and reliable valvetrain operation.

Lifters/Tappets

New lifters/tappets are included to ensure proper camshaft break-in and longevity, contributing to overall valvetrain stability.

Performance Benefits

This camshaft combo can reduce exhaust gas temperatures (EGTs) by 200-300°F, increase bottom-end power, and improve fuel economy by 1-3 MPG, making it ideal for towing and efficiency-focused applications.

Installation Considerations

For a drop-in installation on 12V engines, ensure piston protrusion does not exceed 0.020" and valve face depth is at least 0.055" with a standard head gasket and a 99° intake centerline. If these specifications are not met, an oversized head gasket or valve reliefs may be necessary. It's crucial to check clearances during installation.
