2026 Roush Stage 3 Mustang — Specs, Price & Review

Overview

ROUSH Performance has been transforming Ford vehicles since 1988. Jack Roush — NASCAR legend, co-owner of the Roush Fenway Racing team — built the company on the belief that American performance engineering could match or exceed anything coming from Stuttgart or Munich. The Stage 3 Mustang is the clearest expression of that philosophy.

The ROUSHcharger Phase 2 supercharger is a ROUSH-engineered positive displacement unit specifically calibrated for the 5.0L Coyote V8. Unlike aftermarket kits that adapt generic superchargers, the ROUSHcharger is engineered as an integrated system — intake, intercooler, fueling, and ECU calibration all developed together. The result is 750 hp and 670 lb-ft of torque delivered with factory-quality drivability: cold-start behavior, idle quality, and part-throttle response that feel like factory engineering, not a bolt-on build.

The ROUSH Stage 3 package extends beyond the supercharger. The exterior aero kit includes a ROUSH-designed front fascia, side rockers, rear spoiler, and hood with functional heat extractors. The suspension package lowers the car 1.5 inches and installs ROUSH-tuned springs and shocks with stiffer front and rear sway bars. Brembo brake upgrades handle the increased performance demands.

Every Stage 3 Mustang carries ROUSH certification and is backed by ROUSH's 3-year/36,000-mile limited warranty — the same coverage offered on factory Ford vehicles, applied to all ROUSH-installed components. This matters at resale: ROUSH-certified, warranted vehicles command a premium over comparable aftermarket builds in the collector market.

Costs & Comparison

Ownership Costs

Stage 3 ownership involves supercharger-specific insurance at $3,000–$4,500 annually. ROUSHcharger requires belt inspection every 20,000 miles — budget $200–$400. The 750 hp power level means brake and tire consumables are the primary ongoing cost.

Frequently Asked Questions

What is the difference between ROUSH Stage 1, 2, and 3?

Stage 1 is a visual/exhaust package with no power upgrade. Stage 2 adds the suspension and brake package. Stage 3 is the complete build: ROUSHcharger supercharger, full aero, suspension, and brakes. Stage 3 is the only ROUSHcharged variant.

Does the ROUSH Stage 3 void the Ford warranty?

ROUSH-installed components are covered by ROUSH's 3-year/36,000-mile warranty. Ford's factory warranty covers base vehicle components that ROUSH has not modified. ROUSH is an authorized Ford SVT partner and has designed the build to preserve as much Ford warranty coverage as possible.

How does the Stage 3 compare to a Shelby Super Snake?

Both deliver 750-825 hp from supercharged 5.0L V8s. The Super Snake is slightly more powerful and carries stronger collector brand recognition. The Stage 3 is less expensive and available through ROUSH's dealer network, making it more accessible. Both are genuine performance builds with proper warranties.

Can the ROUSH Stage 3 be serviced at a regular Ford dealer?

Ford dealers can service the base Mustang components. ROUSH-specific components (supercharger, suspension, exhaust) should be serviced at a ROUSH-authorized center. ROUSH maintains a dealer network; check roushperformance.com for authorized locations.

Is the ROUSH Stage 3 available through Ford dealers?

Yes — ROUSH has partnerships with select Ford dealers who can order and sell Stage 3 Mustangs. This allows dealer financing and trade-in options that buying directly from a custom shop may not provide.

What fuel does the ROUSH Stage 3 require?

91 octane minimum is required for the ROUSHcharger calibration. 93 octane is recommended for maximum performance and to protect the engine under sustained high-load conditions.

What is the top speed of the ROUSH Stage 3?

The Stage 3 is electronically limited to 155 mph in standard configuration. With the electronic limiter removed (track use only), the car is capable of 185+ mph based on power and aerodynamics. Do not exceed legal speed limits on public roads.

Does ROUSH offer track support or performance driving events?

Yes — ROUSH Performance hosts track events and provides technical support for Stage 3 owners. The ROUSH Performance Club offers member pricing on track days, parts, and service. Details at roushperformance.com.
