The Ford Mustang GT Underdrive Pulley Kit by BBK is a high-performance upgrade designed for 2001 to 2004 Mustang GT models. Crafted from CNC billet aluminum, this 3-piece kit offers significant horsepower gains and enhances engine efficiency by reducing the parasitic draw from accessories.
This top-tier pulley kit increases engine output by slowing down the accessories, thus achieving an average of 8-15 additional horsepower over stock pulleys. Engine efficiency is further improved by the reduced weight of these pulleys compared to the original.
