Description
This Lightweight Crankshaft Pulley is stock diameter (OEM sized) crank pulley, utilizing the original belt layout. Since the crank pulley diameter is unchanged, they maintain alternator output at exactly stock output levels so you need not worry about flat batteries or weak charging capabilities. Through extensive weight savings afforded by 6061 aircraft aluminum construction, power gains of up to 10% are available depending on how your MINI is set up. crank pulleys come fully balanced and counter-weighted, and feature anodizing for superb wear resistance & strength.
