Torque Solution Lightweight Crank Pulley w/ Install Kit 08-14 WRX / 08-21 STI / 08-11 Impreza

Torque Solution Lightweight Crank Pulley is engineered to deliver both performance gains and superior durability compared to the factory unit. One of its key advantages is the increased mounting surface area between the pulley and crankshaft, ensuring a more secure fit and eliminating the risk of the pulley working loose under load.

CNC-machined from lightweight 6061-T6 billet aluminum, this pulley reduces rotational mass by approximately 3.5 lbs compared to OEM. The result is faster throttle response, improved acceleration, and more power transferred to the wheels—all without compromising strength or reliability. A sleek black anodized finish adds protection against wear while maintaining a clean, professional appearance in your engine bay.
