Product Description

The PERRIN PSP-ENG-106RD Red Lightweight Crank Pulley is a performance-oriented upgrade designed to reduce crankshaft rotating mass on select Subaru and Toyota FA/FB-series engines. By replacing the heavier stock crank pulley with this lightweight CNC-machined unit, your engine experiences less rotational resistance, enhancing throttle response and giving revs a more energetic feel without altering peak power outputs.

Finished in durable red anodize, this crank pulley improves engine bay aesthetics while maintaining corrosion resistance. It's engineered with precision grooves to support optimal belt alignment and includes a small hub tailored for FA/FB configurations found in Crosstrek, Impreza, Ascent, Forester, Legacy, Outback, WRX, BRZ and GR86 models from 2017-2024. Installation is straightforward with common hand tools and does not require ECU remapping to function, though additional tuning can help unlock further performance benefits.
