The 3k Governor Spring Kit or GSK is a combination of custom designed springs and unique seats. The GSK is designed to allow your truck to enjoy the benefits of full fueling through 3000 rpms. The result is a truck that is much more responsive and fun to drive.
Dramatically changes the driving experience by making your truck much more responsive at the upper end of the rpm band. Highly recommended for anyone with the short rear-end gears... especially if you tow heavy.
Try this kit and see why our competition is screaming about it (yes we've actually had phone calls).
