Hamilton Cams 07-CC-12V188 188/220 Camshaft Combo for 1989-1998 Dodge Cummins 5.9L 12V

Hamilton Cams 07-CC-12V188 188/220 Camshaft Combo

The Hamilton Cams 07-CC-12V188 188/220 Camshaft Combo is designed to optimize the performance of 1989-1998 Dodge Cummins 5.9L 12-valve engines. This complete kit includes a camshaft, heavy-duty pushrods, 165 lb conical valve springs, retainers, locks, and lifters/tappets, providing a well-rounded upgrade for enhanced mid-range power and durability.

Detailed Product Description

188/220 Camshaft

The camshaft offers a duration of 188° intake and 220° exhaust at 0.050" lift, allowing for improved airflow and throttle response. It performs efficiently within an RPM range of 1,700 to 4,500, making it ideal for mid-range power gains, lower exhaust gas temperatures (EGTs), and applications requiring increased durability.

Heavy-Duty Pushrods

Included in the kit are heavy-duty pushrods engineered to handle power levels ranging from 500 to 750 horsepower. These pushrods ensure reliability under high stress and increased loads, supporting a wide range of performance enhancements.

165 lb Conical Valve Springs with Retainers and Locks

The 165 lb conical valve springs deliver increased seat pressure to prevent valve float at elevated RPMs and boost levels. The springs come with retainers and locks, ensuring a secure and stable valvetrain under demanding conditions.

Lifters/Tappets

The kit includes lifters/tappets designed for proper camshaft break-in and long-term valvetrain stability. These components ensure compatibility and seamless integration with the camshaft for efficient engine operation.

Performance Benefits

This camshaft combo is tailored to reduce EGTs by 200-300°F, increase mid-range torque, and improve fuel economy. It is an excellent choice for various setups, including larger single or compound turbos, weekend performance builds, stock class pulling, and drag racing.

Installation Considerations

For a straightforward drop-in installation, the piston protrusion must not exceed 0.020", and the valve face depth should be at least 0.055" with a standard head gasket and a 99° intake centerline. If these parameters are not met, an oversized head gasket or valve reliefs may be required. It is essential to verify all clearances during the installation process.
