Roush 2021–2025 Ford F-150 5.0L V8 Supercharger Kit – 705 HP / 635 lb-ft Torque

Transform your 2021–2025 Ford F-150 5.0L V8 into a true powerhouse with the Roush 705 HP Supercharger Kit. This complete performance upgrade delivers massive gains in horsepower and torque, engineered for drivers who want unmatched speed, towing strength, and everyday drivability.

Unmatched Power & Performance
This kit features the advanced Roush TVS R2650 (2.65L) supercharger system, boosting your truck’s output by an incredible 305 horsepower at the crank compared to stock. On the dyno, it’s produced 564 rear-wheel horsepower (RWHP) and 508 rear-wheel torque (RWTQ), calculated at a 20% parasitic loss.

• Immediate Power Delivery – Unlike turbochargers, the roots-style Roush R2650 delivers instant throttle response across the entire power band.

• High-Efficiency Cooling – A 107% larger low-temp radiator (LTR) doubles the cooling capacity over past models, keeping performance strong under heavy loads or hot conditions.

• Optimized Calibration – Tuned by Roush for 93 octane fuel (compatible with 91 octane), ensuring maximum performance, reliability, and drivability.

Premium Components & Engineering

• Forged Aluminum Crankshaft Damper – A Roush-exclusive viscous damper that reduces torsional vibration, protecting your engine under high load.

• Specialized Spark Plugs – Designed for forced induction to prevent pre-ignition and maintain smooth, powerful combustion.

• Twin Four-Lobe Rotor Design – The 170-degree twisted rotors improve airflow and thermal efficiency while reducing noise and vibration.

Proven Durability
Roush put this kit through 900+ hours of dyno testing and extreme weather trials, from -20°F cold starts to scorching heat, to ensure it stands up to towing, racing, and daily driving demands.
