The pulley comes specifically maintaining the stock diameter so as to not under drive and cause electrical woes for the owner, as well as maintaining the stock drive belt surface to make for a quick and easy install by even the most novice of owners. Pulley weight is 1.2lbs.
Why?
The COBB Tuning Lightweight Main Pulley is CAD designed and CNC machined from Billet 6061-T6. It is then anodized to withstand the toughest of under hood conditions. Replacing the factory main pulley, the lightweight unit improves acceleration by reducing the rotational mass of the stock unit by as much as 4lbs.
