The BD Diesel governor spring kit for P7100 pumps raises mechanical governor speed to 4,000 rpm on 1994–1998 Dodge 12-valve applications, extending usable rpm and throttle response for modified setups. These kits replace key pump components and must be installed by a qualified technician with P7100 training; improper installation can cause heat, smoke or damage. The kit includes intake valve springs and hardware.
