Billet Lower Pulley Ring
Made from 6061-T6 billet aluminum, this ring provides a 27% increase in supercharger speed. When combined with supporting mods consisting of a TC Fab intake, 60# inectors, and a tune, gains of 83rwhp and 117rwtq have been reported. K080570 belt required.
Installation takes 1-2 hrs with basic hand tools.
Pinning the balancer is strongly recommended. The TC-Fab pin kit is specifically designed for the LC3 engine and works great.
