Callaway is best known for tuning Corvettes, but that hasn't stopped the company from focusing on other niches. Like trucks.

The Callaway Silverado is the first in a line of Callaway SportsTrucks, and the package offers more power and unique styling for Chevrolet Silverado owners.

There are two variations: The SC450 and the SC540. The first makes 450 horsepower and 450 lb-ft of torque using the 5.3-liter V-8, while the second makes 540 horsepower and 522 lb-ft using the 6.2-liter V-8. Both engines have an Eaton Roots-style supercharger, a liquid-to-air intercooler, increased flow-rate fuel injectors, carbon-fiber injector covers, a high-flow intake system, and low-restriction exhaust system.

Interior upgrades consist of embroidered headrests and floor mats, Callaway interior and exterior badging, custom key fobs, and Callaway documentation. A 3-year/36,000-mile warranty is standard. The package is available with all Silverado cab styles and bed lengths, and with two-wheel or four-wheel drive.

Optional equipment includes a chrome-coat supercharger housing, a nine-spoke alloy wheel/BF Goodrich tire package, a Callaway suspension, a Callaway Le Mans GT braking system, a Callaway Sport interior package, a Callaway Custom-Fit SportTruck cover, factory delivery, and a 5-year/100,000-mile extended powertrain warranty.

The package starts at $15,995. Packages are on the way for the Silverado 2500 HD, the Chevrolet Avalanche, the Chevrolet Suburban, and the Chevrolet Tahoe.
