TR Lightweight Crankshaft Pulley for Subaru BRZ / Scion FR-S / Toyota FT-86

Introducing the latest release of lightweight pulleys for the Subaru BRZ, Scion FR-S & Toyota FT-86. Constructed from lightweight billet aluminum, CNC machined with gold anodized, Tomioka Racing lightweight pulley effectively reduces the factory pulley's weight by over 60%, thus allowing the boxer engine to rotate more freely to produce more power and revolutions. Dyno testing shows a horsepower gain of 10WHP* (Wheel Horsepower) by replacing the factory pulleys. Tomioka Racing pulleys are 100% Bolton for simple installation. The lightweight pulleys are available as an individual unit or set of 3-pulleys. Features Billet Lightweight Aluminum Reduces Rotational Mass Gold Anodized 100% Bolt-On CNC Machined
