Interchangeable Crank Pulley Kit with 2 Pulley Rings
1999-2004 Lightning, 2003-2004 Harley Davidson F150
One of the products that made Metco Motorsports famous!
This comprehensive kit allows the user to easily add boost and horsepower to the factory supercharged Lightning and Harley Davidson trucks. The kit installs easily with no modifications or special tools required, and provides for quick and simple boost level changes once installed.
The kit includes a crank pulley hub precision-machined from billet aluminum, two pulley rings of your choice, specially machined tools to hold the engine in position during installation and to break the original crank pulley bolt loose, and Grade 8 fasteners. Pulley ring choices include +2 lb, +4 lb, +6 lb, +8 lb, and +10 lbs of boost over the stock level. Stock-size and 1" smaller than stock size pulley rings are also available for use with Kenne-Bell or Whipple superchargers. Please make your pulley ring size selections below.
Pulley rings are available separately and are also listed in this section.
Note 1: We have heard from some installers that this kit will fit the 2004-2005 Roush F150 with the supercharged 3V engine. It may fit later models using the 2004-2005 harmonic balancer. The +2 lb crank pulley ring provides an additional 2.2 lbs of boost in the Roush application.
Note 2: if your Lightning or Harley Davidson truck is equipped with the ATI balancer for this application (ATI PN 918038), a dedicated pulley hub is available, and listed elsewhere in this section. It can be substituted for the standard crank pulley hub included in this kit at no extra charge.
