This heavy-duty Roush belt tensioner for 2005–2010 Mustang 4.6L 3V is the same tensioner used in 2010 ROUSHcharger kits and serves as a replacement or upgrade for those packages. It’s designed to handle the added rotational forces of supercharged FEAD systems and is intended as the heavy-duty option for single-belt TVS R2300 ROUSH superchargers installed on 2005–2009 Mustang GTs.
