Callaway, known for building hotted-up Camaros and Corvettes, has assembled a package to be applied to Chevy’s trucks and sport-utes. Callaway will build a SportTruck from any Silverado 1500, Silverado 2500HD, Avalanche, Tahoe, or Suburban with a gas engine. The package is the same for each, and tops the engine with an Eaton TVS supercharger not unlike the ones GM uses on the Corvette ZR1 and Cadillac CTS-V. Regardless of engine—5.3-liter, 6.0-liter, 6.2-liter—the cost is $15,995 to upgrade any two- or four-wheel-drive pickup or SUV.The package comes in strength-defined names based on how much power results from the supercharging. Trucks with the 5.3-liter V-8 are called SC450, as the engine’s output is raised to 450 hp and 450 lb-ft of torque, up from the stock 315 hp and 335 or so lb-ft (the output for all of these engines varies from model to model). The 6.0 is christened SC490, with output of 490 hp and 496 lb-ft, up from around 350 and 380. The top-dog SC540 supercharges the 6.2-liter V-8 to 540 hp and 522 lb-ft from stock levels of 403 and 417. The supercharger is accompanied underhood by an intercooler, higher-flow injectors, carbon-fiber injector covers, and a Callaway high-flow intake. A low-restriction Callaway exhaust also is fitted.
Along with the engine upgrades, Callaway dresses up the exterior with subtle badging and adds embroidered headrests and floor mats inside. Additional options include wheel-and-tire packages, upgraded brakes (chef recommends), suspension upgrades, and a sport interior package. Callaway includes a three-year/36,000-mile limited warranty that can be extended to five years/100,000 miles. The trucks and SUVs can be ordered at participating Chevy dealers and are modified at one of Callaway’s U.S. facilities.
