COBB Tuning Lightweight Crank Pulleys
COBB Tuning lightweight crank pulleys are CAD-designed and CNC-machined from billet 6061-T6. They're anodized to withstanding the toughest of under-engine conditions. These lightweight units can improve acceleration by reducing the rotational mass of the stock unit by as much as 4 lbs. The pulleys specifically maintain the stock diameter, so as to not under-drive and cause electrical woes for you; they also maintain the stock drive belt surface for a quick and easy install, by even the most novice of owners. Replace your factory main pulley with the performance of a COBB Tuning lightweight crank pulley. Order the model designed for your vehicle application.
