5.9L VP 98.5-02 Freedom Series Cummins Cylinder Head (Street) Fleece Performance

A ready-to-run Cummins head

Fleece builds its Freedom Series heads in its own cylinder head machine shop to meet or beat factory specs. Every head is inspected, pressure tested, decked and painted, and it arrives fully assembled and ready to bolt on.

Fleece swaps the factory freeze plugs for 11 screw-in plugs, so the head won't leak coolant under the valve cover. It also gets hardened, oversized press-in valve seats and new valve guide liners.

The Street head is aimed at daily drivers and heavy towing and is rated to 700 hp. If your engine will run past factory RPM limits, Fleece says to step up to its Performance head with stiffer valve springs.

Who it's for

Owners of 1998.5-2002 Dodge Ram 2500/3500 with the 5.9L 24-valve VP44 Cummins who need a replacement or upgraded cylinder head.
