Description
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. Pacbrake’s governor spring kits are complete with all parts for 3000 and 4000 RPM and are recommended for vehicles that have 5 speed standard transmissions. They are perfect for those who tow heavy loads and want more responsive power.
NOTE: For 4000 RPM applications it's required to upgrade to 60 PSI valve springs, part # C14010
