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.
