Perrin Performance
PERRIN 19-21 Subaru WRX / 16-18 Forester / 15-19 Legacy Lightweight Crank Pulley - Blue
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
The PERRIN Lightweight Crank Pulley (PSP-ENG-104BL) improves engine response and throttle sensitivity by significantly reducing rotational mass on the crankshaft. Fits select 2015-2021 Subaru WRX, Forester, and Legacy models.
By replacing the heavy OEM steel pulley with a lightweight aluminum version, you reduce the parasitic drag on the engine, allowing it to rev more freely throughout the RPM range. This pulley is designed to maintain the same diameter as the factory unit, ensuring that accessory belt speeds and alternator output remain within original specifications.
- Precision CNC-machined from 6061-T6 aluminum
- Reduces rotational mass for improved throttle response
- Anodized blue finish for superior corrosion resistance and engine bay aesthetics
- Direct replacement for the factory crank pulley using original hardware
- Manufacturer Part Number: PSP-ENG-104BL
