Restore Your Cummins' Performance

Give new life to your engine with Fleece's fully remanufactured Freedom Series Cylinder Heads for 2003-2007 Dodge Ram 5.9L Cummins. These fully remanufactured cylinder heads are meticulously crafted in Fleece's advanced, state-of-the-art cylinder head machine shop, ensuring every head is precision-engineered for exceptional quality and performance. Whether you're looking to replace a worn-out or damaged head, or simply upgrade for improved reliability, the Freedom Series is designed to deliver superior durability and performance for your Cummins engine. Each cylinder head undergoes a comprehensive remanufacturing process, which includes thorough inspection, cleaning, machining, and precision testing. Fleece ensures that all critical components—such as valve seats, guides, and the valve train—are brought back to OEM specifications or even enhanced for better performance and longevity.

Meticulously Tested for Superior Performance

Every Fleece Freedom Series Cylinder Head undergoes a meticulous, multi-step process to ensure it meets the highest standards of quality and performance. First, each head is thoroughly inspected to check for any imperfections, cracks, or other flaws, and then it is pressure checked to verify there are no leaks and that it can withstand the stresses of high-performance use. Next, the cylinder head is then decked and painted to provide a protective finish. For added reliability, Fleece has taken extra steps to address one of the most common concerns with these older or high-mileage Cummins engines: coolant leaks. The 11 screw-in freeze plugs are a key feature of the Freedom Series Cylinder Heads, offering a leak-resistant solution compared to traditional press-fit plugs. With a Heavy Duty Street rating of up to 700 horsepower, the Freedom Series Cylinder Heads are built to provide the performance required for a variety of applications. Whether you're using your truck for work or play, these heads will keep your engine running reliably and efficiently.
