Bolt On Power in Minutes
These reconditioned BBK underdrive pulley kits are one of the easiest ways to free up an average of 8-10 horsepower in under 30 minutes. BBK pulley kits are designed as direct bolt on replacements for the current factory pulleys and retain full cooling and charging characteristics.
Each Mustang underdrive pulley kit comes with complete installation instructions and allow the use of the existing serpentine belt. The SFI approved damper design makes installation even easier than some other kits because you simply swap out the whole balancer instead of stacking them together.
