PacBrake Governor Springs, Dodge (1994-98) 5.9L Cummins 12V, 3000 & 4000rpm

These springs will let your injection pump fuel to around 3000rpms or 4000rpms. These springs are great for the mild to moderate trucks used for towing or having some fun on the weekend. This spring kit come with enough springs to be a 3000 or 4000 rpm kit. So if you only use the 3000rpm springs, you have the option of upgrading to a 4000 down the road with parts you already have. Engines being operated over 3200 RPM should have heavy duty intake and exhaust valve springs installed.
