BBK 3pc Underdrive Pulley Kit (97-03 F150 4.6L/5.4L V8)

Regain Lost HP. Your accessory pulleys can be a parasite on your Ford Truck's drivetrain, sucking away anywhere from 5 to 18HP. Round up those ponies and put them back where they belong - under your right foot - with an underdrive pulley kit from BBK.

Quality Construction. These underdrive pulleys are made from aircraft-quality aluminum alloy, so they're lighter than the factory pulleys while being just as durable too.

Easy Installation. Since these pulleys are direct bolt-on replacements, you'll be feeling the gains in 30 minutes or less. Better still, your Ford Truck will keep its full cooling and charging characteristics, so this mod is all gain and no pain! This complete Ford Truck underdrive pulley kit comes with installation instructions and allows the use of existing 8 rib serpentine belts.

Fitment. This kit fits 97-03 F150's with the 4.6L or 5.4L V8 engine with 8 rib serpentine belts. Will not fit 6 rib serpentine belt equipped trucks.
