AEM Power Pulley Kit for the Mitsubishi Eclipse.

AEM Tru-Power Pulleys increase horsepower by decreasing the parasitic effects that factory accessory pulleys have on a vehicle's engine. The pulley's lightweight 6061 T-6 billet aluminum construction reduces rotating weight and increases efficiency. All pulleys have a tooth profile that is guaranteed to match original equipment (O.E.) specifications, eliminating the chances of premature comprehensive instructions, performance belts, and AEM decals. Removal of torsional vibration damper is NOT necessary.
