Big Power.
Full Warranty Coverage.
Factory Built.

The Callaway Sierra is a powerfully engineered version of General Motors’ T1 pickup truck platform. The trucks are based on Chevrolet’s SLT, AT4 and Denali models, with 4 wheel-drive and 6.2L engine.

Callaway Sierra packages include Callaway’s GenThree™ supercharging and TripleCooled™ intercooling systems, delivering stunning power for breathtaking acceleration and significantly facilitated hauling and towing. The Eaton TVS R2650-based supercharger has 15% more displacement than previous models yet requires 18% less power input. The supercharger is flanked by matte Callaway Carbon mid-covers which conceal coil packs, engine wiring and plumbing. The covers also serve to suppress valvetrain and fuel injector noise.

A Quad Tip stainless-steel dual-outlet exhaust system boosts flow to match newfound power. There is an authoritative acoustic signature and no droning resonance in the cabin.

Underhood and interior build authentication plaques are included to individualize each Callaway Sierra build. Optional interior appointments include Alcantara horn cover with debossed logos and billet accelerator and brake pedal pads.

The truck is 50-state emissions compliant and carries Callaway and GM warranties. Callaway’s 3 year / 36,000 mile Warranty supplements the GM Bumper-to-Bumper Warranty, providing the best coverage of any Specialist manufacturer. Callaway Sierras are assembled to stringent engineering specifications by our expert technicians exclusively at Callaway factories in Old Lyme, Connecticut, and Temecula, California.
