AEM Tru-Power Pulleys increase power by reducing the parasitic drag caused by factory accessory pulleys. Our lightweight pulleys reduce rotating weight and are slightly oversized to maximize efficiency, which nets more horsepower at the wheels. AEM gaurantees their pulleys' belt tooth profiles to match OE specifications, eliminating any chance of premature belt wear. Comprehensive installation, replacement belts and AEM decals are included in every kit.Key Features:
CNC-machined from 6061-T6 billet aluminum.
Properly sized replacement belts included in every kit.
Removal of the torsional vibration damper NOT necessary*.
Manufactured and assembled in the USA.*Important: Vehicle manufacturers have thoroughly investigated the use of torsional vibration dampers and conclude that their use significantly reduces noise, vibration and harshness. Furthermore, manufacturers and independent research shows that torsional vibration dampers are critical to engine life where long-term use is intended. Removing the torsional vibration damper from an engine can be detrimental to it's long-term operation!
