The Governor Spring Kit or GSK is a combination of custom designed springs and unique seats. The 4k GSK is designed to allow your truck to enjoy the benefits of full fueling through 3000 or 4000 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. Note about the 4000 RPM Kit - This kit is designed for a competition or performance oriented truck, you must install 60lb valve springs for this product to be considered safe. You can install the 3000 RPM kit and just retain the two smaller springs for after you install the 60lb valve springs.
