Increased Performance. The BBK Underdrive Pulley Kit is designed to reduce the speed of your accessories, such as air conditioning and alternator, but keep the same factory cooling and charging characteristics. By slowing down the rotation of your accessories, there is less pull or drag on your engine, which frees up about 8-15 horsepower. This kit can be bolted on in less than 30 minutes and the polished finish looks great under the hood.

Quality Construction. This BBK 3-Piece Underdrive Pulley Kit is CNC machined aluminum and features a brightly polished finish. All hardware necessary for this installation is included and reuses your factory serpentine belt to eliminate any guess work.

Application. The BBK 3-Piece Underdrive Pulley Set is designed for the 1997-2003 Ford F-150s powered by the 4.6L or 5.4L Engine. The pulley set is not compatible with the SVT Lightning and 2002-2003 Harley Davidson Models with the supercharged 5.4L V8 engine.

BBK Under drive Pulleys are a great bolt on!

15 horses ,Just for a little over an hour of wrenching,I felt the response immediately. These will pay for themselves quickly by the fuel they will help save.. I highly recommend them!
