Stage 3 Motorsports now offers mustang shaker hood upgrades. The 2005-09 Mustang GT shaker kit will work with a Vortech supercharger kit, but will not work with a "Roots" Style supercharger. The Saleen Supershaker Supercharger is a complete shaker supercharger system. When you are ready for more sound, check out our 2005 Mustang Exhaust section.
