A modern King of the Road, built by Shelby American. This 2021 Ford Mustang Shelby GT500 is Shelby American CSM #21KR0037, a 2024 GT500 King of the Road conversion finished in Ford Performance Blue Metallic with white side and over-the-top stripes over Ebony leather with blue accents. Showing 8,389 miles, it is a properly documented, exceptionally specified modern Shelby with the visual presence and mechanical substance the KR name demands. At its core is Ford's hand-assembled 5.2-liter Predator V8, comprehensively reworked by Shelby American with a Whipple supercharger, revised intake, high-volume intercooler and heat exchanger. Shelby rated the result at 900 horsepower, delivered to the rear wheels through a seven-speed dual-clutch transmission and limited-slip differential. Outlaw G-Force axle shafts and a Shelby-tuned 3-inch cat-back exhaust complete the drivetrain package. The KR specification is unmistakable: carbon-fiber front splitter, rear diffuser, hood vents, rear wing with Gurney flap, Shelby-specific bodywork, hood pins, LED lighting, and brushed-silver 20-inch Shelby forged wheels over Brembo brakes. The chassis is equally serious, with height-adjustable dampers, caster-camber plates, revised sway bars, two-piece ventilated rotors, and Michelin Pilot Sport 4S tires. Inside, the GT500KR-specific Ebony and blue seats carry Shelby and GT500KR embroidery. A carbon-fiber dash panel, Bang & Olufsen 12-speaker audio, SYNC 3 navigation, dual-zone climate control, blind-spot monitoring, and cross-traffic alert retain the factory car's usability beneath the Shelby transformation. Full-front paint-protection film is fitted to the bumper, hood, and front fenders. Shelby American build documentation accompanies the car. The supplied CARFAX report shows two prior owners, five service-history records, and no accidents or damage reported to CARFAX. Additional photography, walk-around video, documentation, and an independent pre-purchase inspection are available on request.
