WHAT THIS DOES
This is the same Roush supercharger kit that’s been turning stock F-150s into 705-horsepower trucks for years — now in a limited run with an exclusive red head unit, built to mark two anniversaries at once: America’s 250th and Roush’s 50th.
Nothing about the performance changed. The supercharger, the power, the calibration, the warranty — all identical to the kit Roush has sold for years. The only difference is what you see when you pop the hood, and it’s not subtle.
Roush isn’t promising this color comes back, and isn’t promising it won’t. What we know is this run is limited — once it’s gone, there’s no set date for another.
WHAT IT’S MADE OF
A complete, intercooled positive-displacement supercharger system engineered and calibrated by Roush specifically for the 5.0L V8 F-150. It includes the blower assembly, intercooler, and Roush calibration, and installs as a bolt-on package that keeps the truck’s drivability intact. Backed by the Roush supercharger warranty.
