The Metco Motorsports auxiliary idler kit for the Lightning is cleverly engineered to be a simple bolt on and to be the ultimate solution to belt slippage.

The kit consists of a heavy-duty, precision-machined aluminum plate that offers an optimized location for the included black hardcoat-anodized 90mm idler pulley.  The plate bolts to existing bolt locations on the vehicle and locates the pulley just to the right of the supercharger pulley, maximizing belt wrap and eliminating slippage.  The necessary fasteners are included, including steel stand-offs precision-machined from high-grade steel as well as a billet bearing cover for the pulley. Illustrated installation instructions are provided.

This product is an original Metco Motorsports design that has been copied a number of times, but none of the copies match the quality and precision fit of the original.

This kit is compatible with both Eaton and Kenne-Bell superchargers, and is also available with a smaller 90mm idler pulley (MLI-90, also listed in this section) for use with larger supercharger pulleys.  Both 90mm and 100mm kits are available with a double-bearing idler pulley upgrade.

These spacers are those originally included with the Metco Motorsports Auxiliary Idler Kit for the 1999-2004 Lightning and supercharged Harley Davidson truck. These two spacers mount behind the billet bracket to provide secure mounting and perfect alignment for the idler pulley to the supercharger pulley.

These spacers are CNC-machined from high-grade steel and then zinc plated for corrosion protection. There are two spacers originally included in the MLI-90/MLI-100 idler kit, one long and one short. The M8 x 25mm hex bolt needed to mount the bracket is also included, but not shown.
