5000 RPM Governor Spring Kit (5K GSK)
This 5,000 RPM kit utilizes the stock idle (large) spring and will idle at stock levels. We have installed this kit in several trucks locally and they all idled great and pulled hard past 4,000 RPM.
Recommended for competition use only, very smooth, better throttle control than the 4K springs.
Will go up to 7k.
Get the kit that is used by several MAJOR pump shops!
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.
