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.
