A lightweight alternator pulley made for 2022–2026 Subaru BRZ and Toyota GR86 models, offered in a black finish. The pulley reduces rotating mass at the alternator to free engine accessory load, serving as a simple drivetrain modification for owners seeking a marginal reduction in parasitic drag from the charging system where a direct-fit replacement pulley is appropriate.
