Roush phase two upgrade kit

The belt will be the hardest to change. The pulley will come right off after you remove the bolt screws. Two hour job.

  • The Roush R2300 to Phase 2 Supercharger Upgrade Kit is designed specifically to the 2011-2014 GT Mustangs with a 525hp, 540hp or 575hp Roush TVS Supercharger Kit already installed. The Cold Air Intake System with 110mm MAF, 6-Rib Serpentine FEAD Belt, and 85mm Supercharger Pulley only fit on the ROUSH TVS for the GT's, and would not fit your V6 Mustang.
