1994-1998 Cummins 4K Governor Spring Kit (232701)
Description
4000 RPM governor spring kit for 1994-1998 Dodge Ram 2500/3500 5.9L 12V Cummins P7100 injection pumps. The most iconic single mod in the 12V Cummins world — pushes full fueling out to 4000 RPM, well past the factory 2300-2400 RPM rolloff that kills top-end power on a stock pump.
Drops into the P7100 pump with no machining or external work. Combined with upgraded turbo and injectors, this is the kit that turned the 12V Cummins from a stock-power truck into the bottom-end-monster diesel that defined the 2nd gen era. Improved throttle response, faster turbo spool, and meaningful power gains across the entire midrange and top end.
Features
- 4000 RPM Governor Spring Kit for P7100 Pump
- Full Fueling Cutoff at 4000 RPM
- Better Throttle Response & Faster Turbo Spool
- The Defining 12V Cummins Pump Upgrade
- For 1994-1998 Dodge Ram 5.9L 12V Cummins
- Part Number: 232701
Notes
- Industrial Injection recommends running their 150 lb valve springs (24G801) with this kit to prevent valve float above 3200 RPM.
- For higher-RPM builds, step up to the 5000 RPM kit (232702).
