Starting with the GT500 Coupe donor car, Shelby adds a new supercharger to the 5.4L DOHC V8 and boosts power up to 725hp (540kW). Other modifications include an upgraded intercooler and radiator, a cold air intake, and a high-flow JBA exhaust system. A milder 630hp (470kW) version, which replaces the JBA exhaust with a Borla cat-back unit, is also available.
Handling improvements come courtesy of a Ford Racing suspension with adjustable dampers, stiffer springs, thicker antiroll bars, a front strut tower brace and custom 20in Super Snake wheels shod with Pirelli P-Zero tires. Stopping power comes from Baer six-piston front calipers with cross drilled and ventilated discs.
To ensure the car stands out from the crowd when off the track, Shelby’s engineers have also fitted a new hood with an oversized scoop and vents, racing stripes, rear quarter window scoops, and carbon-fiber splitter and side sills. Inside, the headrests feature embroidered Shelby logos and carbon-fiber faced gauge faces.
Pricing for the Super Snake package starts at $29,495 for the 630hp (470kW) model and $33,495 for the 725hp (540kW) kit, which includes installation at Shelby Automobiles’ Las Vegas facility or at a Shelby authorized workshop. The first customer cars will be modified this August.

The 550hp (405kW) Shelby SR package is based on the previous 2005 to 2009 Ford Mustang GT.
