BBK Underdrive Pulley Kits

4.67 out of 5 stars 61 Customer Reviews

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 to 15 hp, while retaining full cooling and charging characteristics. Most pulley kits can be bolted on in less than 30 minutes.
