Description

This pulley kit is designed for performance and style, featuring clear powder coating that eliminates the need for polishing. It's made from 6061-T6 aircraft-grade aluminum, with brackets that are 100% thicker than similar products. The components are precision CNC machined and hard-coated to 65 Rockwell "C" scale, making them harder than steel and twice as hard as forged aluminum, which increases pulley life.
