Fleece Performance 01-04 GM Duramax LB7 Freedom Cylinder Head w/Cupless Injector Bore (Pssgr Side)

When you're rebuilding the top end of your 2001-2004 GM Duramax LB7, getting the right cylinder head is crucial. This Fleece Performance Freedom Cylinder Head is specifically for the passenger side and is designed for engines using cupless injectors. It's a well-built replacement that addresses common failure points and aims to improve the reliability of your powerful diesel engine.

This head is constructed from high-strength cast iron, a material chosen for its durability and ability to withstand the high pressures and temperatures found in a Duramax engine. The critical injector bores have been machined to accommodate cupless injector designs, which can offer better atomization and combustion efficiency compared to older designs. This means you're getting a head that's ready for performance upgrades or simply to restore your engine to its peak operating condition with improved components. Fleece Performance is known for producing robust parts for diesel trucks, and this cylinder head is no exception, offering a solid option for serious engine work.

This part is for the passenger side cylinder head only. If you're replacing both, be sure to order the driver's side head separately. It's always a good idea to inspect your valve springs, seals, and any other related components while the cylinder head is off, ensuring everything is in top shape before reassembly. Remember, this head is not CARB approved and cannot be shipped to California.
