BBK 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.
