Part #: AMP-ENG-520

MIA's Description

The ALTA Performance Lightened Crank Pulley (LCP) is engineered to increase horsepower and torque. It is made from 6061T6 aluminum and weighs 0.65 lbs, which is over 2.3 lbs lighter than the stock crank pulley. The ALTA LCP comes in two sizes: 0% (stock sized, lighter rendering of the stock crank pulley, no additional vibration or noise) and +2% oversized (adds more boost to supercharged Cooper S models by effectively shrinking the supercharger pulley size). Unlike some underdriven aftermarket pulleys, the ALTA LCP does not affect the car's charging system.
