Interchangeable Crank Pulley Kit

The Metco Motorsports ICP9903 crank pulley kit is engineered to easily increase boost and horsepower for factory supercharged Ford Lightning and Harley Davidson F-150 trucks. Constructed with a precision-machined billet aluminum crank pulley hub, this kit includes a choice of pulley ring and specialized tools for installation. Users can select from various pulley ring sizes, offering boost increases from +2 lbs to +10 lbs over stock, allowing for customization of performance levels. Stock-size and 1" smaller than stock pulley rings are also available for compatibility with Kenne-Bell or Whipple superchargers. Special fitment notes apply for certain model years and configurations. For 1999-2000 models, the crank pulley hub can be sized to optimally fit the slightly different balancer used in those years if specified at checkout. The kit is confirmed to fit the 2004-2005 Roush F150 with the supercharged 3V engine, and may fit later models utilizing a Lightning-style dual belt system and a harmonic balancer with three threaded holes. Additionally, if your vehicle is equipped with an ATI balancer (PN 918037), a dedicated crank pulley hub is available as a substitute at no extra charge. Note that Metco Motorsports considers their parts race parts and does not accept returns.
