Peak Diesel Performance Governor Spring Kit
1994-1998 5.9L Dodge Cummins 12 Valve
The Peak Diesel Performance Governor Spring Kit is a special combination of Bosch springs and Piers' unique design on seats. The GSK 3000 and 4000 is designed to allow your pump to rev past factory settings without compromising pump safety. The 3K GSK (3000 RPM Governor Spring Kit) works exceptionally well with standard transmission trucks, allowing you to shift at a higher rpm which then allows you to come back into your next gear at a higher rpm. This allows for smoother shifts, less torque on the transmission, and better towing capability. The 4K GSK was specifically designed for racing. It is not recommended for daily driving or towing applications and requires heavy duty exhaust valve springs to be installed. The 4K GSK is available both with and without the heavy duty exhaust valve springs.
