BBK Aluminum Underdrive Pulleys
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.
Identification Guide for 4.6L Water Pump Pulleys
Visually identify which water pump pulley you have before installing regardless of model year. The early water pump pulley
had a convex or ''bowed-out'' face and the pulley on the later water pump has a concave or ''pressed-in face''. There is no
exact changeover date for the pump and pulley. Supposedly the water pump changeover occurred in January of 2000, but we
have seen cars with identical January build dates and different water pumps and pulleys. We have also seen the early design
pulleys used on a few 2002 models,
Refer to the pictures below to determine which pulley design you have. Since there is no definitive answer as to the time line
or model years.
Easy replacement that definitely gives you more seat of the pants power. Definitely recommend this kit as an easy way to start off a project.
Yes, I would recommend this item to a friend!

Good looking kit

While everything pictured was included, I was a bit disappointed by the fact you ave to reuse your balancer and it covers the shiny new pulley! They supply the bolt for it but you still reuse the old rusty washer, and no new nut for the alternator pulley! For the price you would think they would include all new hardware, the pulleys did provide a noticeable pick up in power though.
