BD-Power 4,000 RPM Governor Spring Kit 94-98 Dodge 5.9L Cummins 12 Valve

These heavier coil springs replace the stock governor coil springs to safely allow the engine to reach higher RPMs, so there is no momentum loss when shifting gears while towing up a hill. These are especially a useful upgrade for manual transmission trucks to reduce power lost between gears. They are perfect for those who tow heavy loads and want more responsive power.
