This Mustang GT Supercharger Kit is part of an innovative line of upgradable ROUSH superchargers kits for Mustang GT's -- allowing you to build up power at your own pace. This "phased" supercharger line includes two different FEAD systems. The single belt FEAD kits are comparatively less expensive than dual belt counterparts. However, the dual belt systems allow for improved management of power. This can help particularly in high horsepower applications.

This 2005-2009 Mustang GT Supercharger Kit comes with the standard ROUSH parts and accessories warranty -- 90-days from retail purchase date on ROUSH components only (no labor).
