The Callaway Silverado and Sierra are specialist versions based on General Motors’ GMT K2XX platform. The trucks may be equipped with two-wheel-drive or four-wheel-drive, with any Chevrolet or GMC equipment group, any cab style (regular, double or crew) and any box length (short, standard or long).

Callaway Silverados and Sierras deliver breathtaking power and stump-pulling torque with perfect drivability and bulletproof durability. New SC480 and SC560 SportTrucks are equipped with Callaway’s “GenThree” supercharger system, delivering more power than ever!

These limited production trucks are built with a full complement of Callaway standard equipment and available options as listed below. Callaway’s 3 year/36,000 mile Warranty supplements the GM Bumper-to-Bumper Warranty, providing the best coverage of any aftermarket manufacturer. Callaway Silverados and Sierras are assembled to stringent engineering specifications by expert technicians exclusively at Callaway factories in Old Lyme, Connecticut, and Santa Ana, California.
