Fleece Performance
The Fleece Performance Freedom Series Cummins Performance Cylinder Heads are engineered for high horsepower diesel applications where strength and reliability are critical. Each cylinder head is manufactured in Fleece Performance’s state of the art cylinder head machine shop and is guaranteed to meet or exceed factory specifications.
Every head is fully inspected, pressure tested, decked, painted, and shipped ready for installation. The addition of 11 screw-in freeze plugs eliminates the risk of coolant leaks under the valve cover, a common failure point on factory cylinder heads.
Whether the application is sled pulling, drag racing, or heavy towing, the Fleece Performance 5.9L Cummins Performance Cylinder Heads deliver the airflow and durability needed for serious power. These heads are rated to support up to 1,100 horsepower.
