Keeping the Silverado's factory looks, Callaway didn't try the often over-exaggerated tuner trick of scoops, flares, and body kits, but instead added simple Callaway and SC540 badging where it deemed appropriate. One of the biggest hints to the truck's custom and performance appeal is the gorgeous wheel package. Contemplating different wheel designs in a saturated big-wheel market, the engineers at Callaway bit the bullet and created a 22x10.5-inch nine-spoke wheel that features a cast and flow-formed barrel for added strength during performance maneuvers. Available in silver, black, and chrome, the lightweight wheels can also be ordered in a black chrome finish for a true one-off look. Tires selected to maintain asphalt adhesion are BFGoodrich g-Force T/A KDW, sized 305/40R22.

Inside the Crew Cab, Callaway attempted to spruce up our tester's LTZ trim package by way of a real carbon-fiber steering wheel horn button, aluminum pedals, floor mats with SC540 embroidered on them, and SC540 badging on the dash. All of those additions sound nice, until you see the factory fake wood still in place, factory low-grain leather seats, and factory three-knob radio. Callaway put their focus on making the truck perform at a level GM could've never imagined, but a little interior dress-up would have gone a long way for a truck package that totals more than $30,000.

A Callaway Silverado, or Sierra if you prefer, can be ordered to your specs from one of its 31 authorized dealers nationwide. The best part of these performance packages is they won't void the factory warranty, and Callaway offers its own extended five-year/100,000-mile powertrain warranty. Because of this dedication to engineering and overall product creation, we had a difficult time parting with the keys to the Silverado. The Callaway SC540 is a blast to drive fast, comfortable enough for a daily driver, and unique looking with subtle enhancements that will have people in the slow lane wondering what exactly it was that blew by them.
