Perrin [22-25 BRZ/GR86] Alternator Pulley FA/FB Engines Red

The PERRIN Alternator Pulley for 2022-2025 Subaru BRZ and Toyota GR86 (FA/FB engines) replaces the failure-prone OEM clutch-style alternator pulley with a lightweight CNC-machined 6061-T6 aluminum pulley — just 0.20 lbs vs 0.92 lbs OEM — for sharper throttle response and a dressed-up engine bay.

• Eliminates the OEM clutch-style pulley failure point (knocking noises, charging issues, belt wear)
• Precision-machined grooves sync with OEM and aftermarket belts; no tuning required
• Includes: (1) alternator pulley, (1) flange nut, warranty & instructions
