What is Roush?

American Ford-focused tuner founded by Jack Roush in 1976. Specializes in Mustang performance variants, including supercharged Roush Mustangs.

Roush Performance (sometimes just Roush) is an American Ford-focused tuner house founded by Jack Roush in 1976. The company specializes in Ford Mustang performance variants, with supercharged Roush Mustangs (Stage 3 Roush, Roush Phase 2, etc.) being the headline products. Roush also produces F-150 trucks and various other Ford products.

Jack Roush is one of the most influential figures in American motorsport, particularly NASCAR. Roush Racing (the racing arm) won multiple NASCAR Cup Series championships, including with drivers Mark Martin, Greg Biffle, and Carl Edwards. The racing experience informs Roush Performance street car development. The brand has cultural cachet within American Ford enthusiast circles.

Roush Mustangs typically include supercharger conversions (TVS supercharger added to Mustang GT and GT500 cars), suspension upgrades, body kits, exhaust modifications, and interior enhancements. Power outputs range from 700-850+ horsepower depending on the package. Pricing for a complete Roush Mustang conversion can exceed $30,000 on top of the base Mustang. Roush parts are also sold as aftermarket upgrades for Mustang owners.

Frequently asked questions

Who is Jack Roush?
American automotive engineer and businessman, founder of Roush Performance and Roush Racing. Roush has been one of the most influential figures in American motorsport, particularly NASCAR Cup Series racing where Roush Racing won multiple championships. The Roush Performance street car business began in 1976.
How much does a Roush Mustang cost?
Depends on the package. A Stage 1 Roush Mustang (basic supercharger and styling upgrades) starts around $50,000-$60,000 (including the base Mustang). A Stage 3 Roush (more aggressive supercharger and complete package) can exceed $80,000. The most extreme Roush variants (Phase 2 with 850 horsepower) push above $100,000.
Are Roush parts factory-warrantied?
Roush products carry their own warranty (typically 3 years/36,000 miles for parts and labor). Modifying a stock Mustang with Roush parts may void some Ford factory warranty coverage on related drivetrain components. Roush sells through Ford dealers in some cases; the relationship with Ford warranty coverage varies by specific package and dealer.
How is Roush different from Saleen?
Both are American Ford-focused tuners. Roush has emphasized supercharger upgrades and motorsport heritage. Saleen has emphasized complete vehicle conversions including bodywork. Both produce performance Mustangs with different aesthetic philosophies. Roush Mustangs tend to look more closely related to stock Mustangs; Saleen Mustangs typically have more dramatic bodywork.
Did Roush invent the Mustang Cobra Jet?
No, the Cobra Jet name belongs to Ford and was originally used in the late 1960s. Modern Mustang Cobra Jet drag racing cars (factory drag race-only Mustangs sold for drag racing competition) are Ford products developed with various contributors. Roush has separate Mustang lines under its own branding.
