2021-2026 Roush F-150 Supercharger Kit | 705HP — Red Edition

705 Horsepower. One New Color. Two Reasons to Celebrate.

This is the same Roush supercharger kit that's been turning stock F-150s into 705-horsepower trucks for years — now available in a limited run with an exclusive Red head unit, built to mark two big anniversaries at once: America's 250th and Roush's 50th.

Nothing about the performance changed. The supercharger, the power, the warranty — all identical to the kit we've sold for years. The only thing different is what you see when you pop the hood, and it's not subtle.

We're not promising this color comes back. We're also not promising it won't. What we know is this run is limited, and once it's sold out, there's no set date for the next one.

Why F-150 Owners Choose This Kit

You want real power, not a tune. A software tune can squeeze a little more out of your stock engine. This kit adds a supercharger — physically force-feeding your 5.0L more air — for a 305 HP gain at the crank, achieving 564 RWHP and 508 RWTQ on the dyno at 20% parasitic loss. That's the difference between optimizing what you have and changing what you have.

You don't want to lose your factory truck. All your OEM drive modes still work. Tow/Haul, Sport, Normal — none of that goes away. Vehicle top speed isn't altered either. You're not trading daily drivability for power.

You want power you can trust on the highway, towing, or in summer heat. Roush tested this kit through 900+ hours on the dyno and cold starts down to -20°F. The radiator is 107% larger than earlier versions, roughly doubling cooling capacity, specifically so the kit doesn't fade under load.

You want a warranty, not a gamble. A 3-year/36,000-mile limited powertrain warranty applies when installed by an ASE-certified tech. This isn't an aftermarket part that voids your protection — it's backed like one.

You want something nobody else on the lot has. The Red Edition pairs the same battle-proven R2650 supercharger with an exclusive Roush Red finish, available only on this limited run.

Built to Perform, Built to Last

• Forged Aluminum Crankshaft Damper — Roush-exclusive viscous damper that manages torsional demands and protects engine longevity
• Forced-Induction Spark Plugs — spec'd specifically to reduce pre-ignition risk under boost
• Instant Throttle Response — the Roush R2650 TVS delivers power across the entire band immediately, unlike a turbo's spool-up delay
• 2.65L Roots-Type Design — twin four-lobe rotors with a 170-degree twist for efficient airflow and reduced vibration and noise

Why Now?

Everything under the hood is identical to the kit that's already earned its reputation on the street, the highway, and the worksite. The same dyno-proven power. The same factory-warranty protection. The same engineering that only comes from 50 years of doing this in Livonia, Michigan. The only difference is what it looks like when you pop the hood — and that difference is unmistakable. Whether this finish returns depends entirely on the people who want it. For now, this is the run.
