Description

This pulley enhances throttle response, horsepower, and torque by reducing rotational mass. Constructed from 6061 billet aluminum, it weighs only 0.2 lbs, significantly less than OEM pulleys, and features a black anodized finish.

Precision-machined grooves ensure a secure fit with belts, while the lightweight design reduces engine strain for a more responsive driving experience. The pulley comes with an M17 Zinc Flange Hex Nut and installation instructions. It is backed by Torque Solution’s Limited Lifetime Warranty.
