More Power in Minutes
These BBK 2005-2010 Mustang GT underdrive pulley kits are one of the easiest ways to free up an average of 8-15 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.
The SFI approved underdrive pulley kit features a high quality steel damper. This simplifies installation because it doesn't require you to stack on your factory balancer ring. Since they meet SFI approval they are approved for use in most sanctioned racing groups.
Each kit comes with complete installation instructions and allow the use of the existing serpentine belt. Installation requires no special tools and can be accomplished in around a half hour.
