The Callaway Silverado Signature Edition features a factory GM 6.2L L87 V8 engine with an Eaton TVS R2650 supercharger, a revised intake and a Callaway “Triple Cooled” intercooler setup, which produces 585 horsepower at 6,250 rpm and 567 pound-feet of torque at 3,850 rpm. For reference, a stock 6.2L L87 V8 makes 420 horsepower and 460 pound-feet of torque, so Callaway’s upgrades are good for an extra 165 horses and 107 pound-feet. The engine also gets some cosmetic upgrades in the way of carbon fiber valve covers, Callaway badging and an underhood plaque with a serialized build number.
Elsewhere, the Callaway Silverado Signature Edition will feature a full Callaway exhaust with quad tips, a carbon grille, chrome Callaway exterior badging, Alcantara interior trim and anthracite or satin black Callaway alloy wheels. Customers will also be able to optionally equip a body color grille, black chrome wheels and black exterior badging.
Callaway says this supercharged upgrade package will be offered on the Silverado 1500 Trail Boss, LTZ and High Country models with the 6.2L L87 V8 engine and either two-wheel-drive or four-wheel-drive. Modified Callaway vehicles are 50-state emissions compliant and do not void GM’s original bumper-to-bumper warranty. They also come with a separate three-year/36,000 mile warranty for all Callaway-installed parts and can be ordered from and serviced at regular GM retail storefronts, which can potentially make a Callaway product a safer bet than a build from another aftermarket company or tuning shop.
Order books for the Callaway Silverado Signature Edition are open now, although Callaway has not publicly revealed the base price at this time.
