Performance underdrive pulley kits are built from aircraft-quality,
computer-machined steel or aluminum alloy. By reducing the speed of the
accessories, these underdrive pulleys free up an average of 8-15 hp,
while retaining full cooling and charging characteristics. Most kits can
be bolted on in less than 30 minutes.
