Show original supplier description

The Metco ICP9903 is a precision-machined, lightweight aluminum interchangeable crankshaft pulley kit designed to replace the factory assembly in supercharged F-150 Lightning and Harley Davidson trucks. This kit offers a significant performance upgrade by allowing users to easily swap between different pulley rings to adjust boost levels. The pulley ring choices provide a range of boost increases over stock, including +2 lbs, +4 lbs, +6 lbs, +8 lbs, and +10 lbs of boost. The kit includes options for stock-size pulley rings and a 1-inch smaller than stock size pulley ring, which is suitable for use with Kenne-Bell or Whipple superchargers. The hub material is also aluminum, contributing to the overall weight reduction. Installation is straightforward, with no permanent modifications required. The kit typically comes with hardware and may require a 14mm hex bit or a specialized tool for installation if the original crank pulley assembly is still in place. The interchangeable nature of the pulley rings allows for quick and simple boost level adjustments once the kit is installed. This kit is specifically designed for 1999-2004 Ford F-150 Lightning and Harley Davidson models, and may fit later models utilizing the Lightning-style dual belt system and a harmonic balancer with three threaded holes.
