The C19 kit includes the same type of Eaton TVS supercharger that can be found under the hood of the Cadillac CTS-V, plus a liquid-to-air intercooler, carbon Ffber injection covers, low-restriction exhaust and plenty of Callaway badging.
The official price tag for the components needed is $15,995, and that will net you 450 horsepower at 6,200 rpm and 450 pound-feet of torque at 4,000 rpm if you're modifying the 5.3-liter, and 540 horsepower at 6,200 rpm and 522 lb-ft at 3,800 revolutions if you're tweaking the 6.2-liter V8. The package also comes with a three-year, 36,000-mile Callaway powertrain warranty, with the option to upgrade to five years and 100,000 miles. And since the 5.3-liter and 6.2-liter V8 engines are available on several GM trucks, ranging from the Tahoe to the Suburban, that means this mod kit is available to more than just the Silverado 1500.
