The stock P7100 governor pulls fuel early, so a 12 valve falls flat right where a manual transmission truck wants to pull through the gear. Upgrade with the Pacbrake HP10029 governor spring kit to carry fuel further up the rev range. It fits 1994-1998 Dodge Ram 2500 and 3500 with the 5.9L 12 valve Cummins and Bosch P7100 injection pump.

RPM range: Parts to set the Bosch P7100 for either 3000 or 4000 rpm, your choice at install. No core charge applies to this part.

Key Features & Benefits

• Best match: Recommended by Pacbrake for 5 speed manual trucks and for heavy towing where more responsive power is wanted.
• Valve springs: Not included. Pacbrake suggests 60 lb heavy duty valve springs (Cummins 3916691) with any governor spring install so the valves do not float at the higher rpm.
