You probably know Callaway Cars as the Corvette specialists who focus on improving Chevy's sports car through engine modifications and wagon-style hatch replacements. But Corvettes aren't the only GM vehicles Callaway designs upgrades for. It also offers a package for the Silverado pickup—one that makes it quicker in a straight line than Ram's Hellcat-powered 1500 TRX.

Dubbed the Callaway Silverado SC602, this super truck uses a Silverado 1500 with the 6.2-liter V-8 and 10-speed automatic as a base. Callaway adds a supercharger, its own intake system, a low-restriction exhaust, and an ECU tune to extract a total of 602 horsepower and 560 lb-ft of torque. The SC602 also gets a host of cosmetic upgrades, including alloy wheels, a carbon grille, a host of Alcantara-covered trim pieces, and a plaque mounted in the cabin.

While the SC602 might not make as much power as the 702-horsepower Ram, its 1260-pound weight advantage (according to Callaway) is enough to eek out a better quarter-mile time versus the TRX in a straight-up drag race. And while the Ram is able to beat out the SC602's 0-60 time, it's the Callaway that reaches 100 mph first.

Of course, what the SC602 doesn't have are all of the suspension, chassis, and tire upgrades found in the TRX. So while it may be quicker in a straight line, we wouldn't recommend flying over dunes or smashing over giant rocks in the Callaway truck.
