COBB Lightweight Crank Pulley Black 2002-2014 WRX / 2004-2021 STI / 2005-2009 Legacy GT / 2005-2009 Outback XT / 2004-2013 Forester XT

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.

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.

This part is legal for sale and use on Emissions Controlled Vehicles in all 50 states when used in accordance with the manufacturer's application guide because it has a California Air Resources Board (CARB) Executive Order (EO) number:
