At its core, the RS/X packs a custom-built engine topped with a Magnuson Supercharger, producing a clean 1,000 horsepower. Breathing through Kooks Headers and a Corsa Performance Exhaust, the truck delivers ferocious throttle response and a signature SPEC sound that commands attention. Each engine is hand-assembled under SPEC’s precision program, blending brute power with refined engineering.

Ride quality and control come from a QA1 adjustable performance suspension, balancing daily comfort with track-ready handling. Braking is handled by Rotora carbon-ceramic rotors — 405×36 mm fronts with 8-piston T6 forged calipers and 380×32 mm rears with 4-piston units — delivering supercar-grade stopping power and thermal stability.

Every RS/X rides on Forgeline Center Lock forged wheels wrapped in Toyo high-performance tires, tailored for maximum grip and durability. The combination creates a chassis feel that’s precise, planted, and undeniably purpose-built for pure enjoyment, utility, and daily driving.

Aggressive lines and lightweight construction define the RS/X, thanks to Anderson Composites carbon-fiber bodywork crafted for strength and style. Putco Lighting adds a distinct LED presence, while Katzkin leather transforms the interior into a driver-focused cabin of luxury and performance.

Through SPEC’s exclusive PTS (Paint-to-Sample) Individualization Program, each truck can be configured through dozens of available options — paint formulas, stitched patterns, trim packages, and custom hardware. No two RS/X trucks are the same. Once an owner selects their spec, the truck becomes a truly one-of-one creation, representing their vision of performance art on wheels.
