Description

It retains the stock drive belt surface, ensuring a quick and easy installation process, even for novice owners. Constructed from Billet 6061-T6 aluminum, this pulley is CAD designed and CNC machined for precision. Its anodized Stealth Black finish provides durability and resistance to tough under-hood conditions. By replacing the heavier factory main pulley with this lightweight unit, you can improve acceleration due to a reduction in rotational mass of up to 4 lbs. The pulley itself weighs only 1.2 lbs. This component is 50 State Legal and has a CARB Executive Order (EO) number D-660-248, making it legal for sale and use on emissions-controlled vehicles nationwide. It utilizes the factory crank pulley bolt for installation and is designed as a direct fit for numerous Subaru models equipped with EJ20 and EJ25 engines.
