Dynomite Governor Springs, Dodge (1994-98) 5.9L Cummins 12V, 3000 & 4000rpm
These Governor springs should have come in your stock truck. Gone will be the days of only 2000rpms worth of power. These springs (depending on how much power you have) 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. These springs come with enough springs to be a 3000 or 4000 rpm kit. Now you can buy one set of springs and have both in case you need more rpm some day Engines being operated over 3200 RPM should have heavy duty intake and exhaust valve springs installed.
