(1) Set of 2 (Crank & Alternator) Under Drive Pulleys
BBK now offers SFI approved performance pulley kits with a SFI approved Steel crank damper for 2005-10 Mustang GT. Built from high quality CNC machined aluminum & Steel each BBK Mustang underdrive pulley kit is designed as a direct bolt on to replace the stock pulleys that rob your engine of horsepower.
Each Mustang SFI underdrive pulley kit is designed specifically for each vehicle. This pulley kit for the 2005-2010 Mustang GT – is designed as a 2 piece kit. As with our traditional pulley systems horsepower gains are approximately 9-12 rear wheel horsepower which is a result of the reduced drag which also helps with overall fuel economy. As with all Mustang BBK parts these SFI approved pulley kits offer BBK's distinctive quality that guarantees many years of top performance.
ALL Mustang BBK performance under drive pulley kits use existing factory 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 4.6L 3V Mustang GT!
