The factory governor springs in your P7100 injection pump slow the fueling as RPM’s begin to climb, leading to a loss of power when you need it most. These Power Driven Diesel Governor Springs are assembled using all genuine Bosch components. With these components you will experience a stronger idle and higher RPM capability compared to typical 4K kits. While all 12-valves can benefit from these springs, manual transmission trucks will especially notice a difference between gears, as these will not allow the fueling to drop off so hard when shifting, making the transition much smoother. They are perfect for those who tow heavy loads and want more responsive power. 60Lb valve springs are required for over 3200RPM to avoid valve float.
