BBK Aluminum Drive Pulleys for 1997-2004 4.6L or 5.4L F-Series Trucks.
1997-2004 FORD 4.6L/5.4L F-SERIES/EXPED 3 PC UNDER DRIVE PULLEYS (ALUMINUM)Install a set of BBK performance underdrive pulleys and see an average of 8-15 additional horsepower over the stock pulleys. Under drive pulleys increase engine output by reducing the draw of the engines accessories by slowing them down and reducing the HP they use. Additional and significant performance improvements can be seen by reducing the weight of the pulley versus the original pulley which is why we recommend the BBK CNC Machined billet aluminum pulley kits for maximum horsepower gains. ALL BBK pulley kits are designed as direct bolt on replacements for the current factory pulleys and retain full cooling and charging characteristics. BBK under drive pulley kits are vehicle specific and each kit comes with complete installation instructions and allow the re-use of existing serpentine belts.-1997 Ford F-150-1997 Ford F-250-1998 Ford F-150-1998 Ford F-250-1999 Ford F-150-1999 Ford F-250-1999 Ford F-250 Super Duty-1999 Ford F-350 Super Duty-2000 Ford F-150-2000 Ford F-250 Super Duty-2000 Ford F-350 Super Duty-2001 Ford F-150-2001 Ford F-250 Super Duty-2001 Ford F-350 Super Duty-2002 Ford F-150-2002 Ford F-250 Super Duty-2002 Ford F-350 Super Duty-2003 Ford F-150-2003 Ford F-250 Super Duty-2003 Ford F-350 Super Duty
