VMP 10-rib Full-FEAD kit for Gen3R Supercharged Coyote AC - 20% OD. This version is for front covers that have not been ground on. Also works with Roush and VMP 2.3 L blowers. If your front cover was previously ground you will need to purchase a "woAC" kit which includes the AC bypass bracket, you can later add AC by purchasing the AC pulley separately.
