The Perrin Alternator Pulley is a machined 6061T6 billet aluminum replacement for the OEM alternator pulley on the 2022+ Subaru Outback Wilderness. It weighs about 0.20 lbs, less than the stock pulley, and Perrin says the lighter rotating mass sharpens throttle response and frees a little horsepower and torque. The precision-machined grooves are cut to match the Perrin Crank Pulley and work with OEM and aftermarket belts. It suits Outback Wilderness owners who want to remove a known wear point and dress up the accessory drive; the gain is modest, and the OEM pulley is the safer choice for anyone who does not want to touch the charging system.

The Perrin Alternator Pulley is a replacement for the OEM alternator pulley on the 2022+ Subaru Outback Wilderness. The OEM pulley can fail over time, which can cause a knocking noise, battery charging issues, belt wear and a jumpy belt. This pulley removes that failure point.
It is machined from 6061-T6 billet aluminum and has a black anodized finish. The grooves are precision-machined and laser etched for a precise fit and longer belt life. They fit OEM and aftermarket belts, and the pulley is designed to match the Perrin Crank Pulley.
The pulley weighs 0.20 lbs, which is lighter than the OEM pulley. Throttle response, horsepower and torque are all increased. It is easy to install.
