5000 RPM Governor Spring Kit (5K GSK)
This 5,000 RPM kit does not utilize the stock idle (large) spring. We only recommend using these springs when your pump is sitting at a qualified pump shop being calibrated on a test stand. We have NOT had the best luck on installing these on a truck without having the pump benched to get the engine to idle correctly.
5000RPM kits required use of heavy duty valve springs, we also reccomend titanium retainers & keepers.
Other engine upgrades are needed to run 5000 RPMs.
Fits 1994-1998 Dodge 12 Valve Cummins diesels.
