Made from aircraft quality machined steel or aluminum alloy these BBK Mustang under drive front accessory pulley kits are one of the easiest ways to free up an average 8-15 horsepower in under 30 minutes.
These Mustang BBK pulley kits are designed as direct bolt on replacements for the current Ford factory pulleys and retain full cooling and charging characteristics.
Each BBK Mustang under drive pulley kit is vehicle specific. They are designed and tested at the BBK headquarters in Southern California for maximum performance.
These under drive pulley kits are available in a hand polished aluminum finish or gloss black powder coated steel. Each Mustang pulley kit comes with complete installation instructions and allow the use of existing serpentine belts.
Due to the difference in diameter from the stock Mustang pullies, the alternator and charging system may need to be upgraded if you have a large stereo system.
These BBK Mustang underdrive pullies work great on a stock or modified V8 GT or LX Mustang!
I have had underdrive pullies on my 06 GT and they didn't quite fit right. Had to have a machine shop modify a few things. These on the other hand fit perfect! And if you're good with a wrench you can have this done in under one hour. Although I do recommend a slightly shorter than stock belt, just for tension reasons.
