The truck business isn’t exactly a glamorous segment for aftermarket companies. Not because there’s a shortage of companies willing to fine-tune a monster of a truck, but more so because the appeal these days can be found in other automotive segments.

That being said, let’s not sleep on these heavy-duty bad boys just yet, especially when you have a tuning company like Callaway in the mix. Noted for their work on sports cars and muscle cars, the aftermarket tuning specialists went the way of trucks for their latest program: a modification kit for the Chevrolet Silverado 1500.

Available for both the 5.3-liter and 6.2-liter versions of the Silverado, Callaway’s “C19” engine kit allows the hulking Chevy SUV to produce as much as 540 horsepower at 6,200 rpm and 522 lb/ft of torque at 3,800 rpm for the 6.2-liter version of the Silverado. Meanwhile, the 5.3-liter version gets 450 horsepower at 6,200 rpm and 450 lb/ft of torque at 4,000 rpm. Another important detail to consider is that even if you don’t have a Silverado 1500, Callaway’s engine kit can also be used on other GM trucks that share the same engine with the Silverado, from the Tahoe->ke472 all the way up to the Suburban->ke263.

Other items that are a part of the package include a liquid-to-air intercooler, carbon fiber injection covers, a low-restriction exhaust, and a three-year, 36,000-mile Callaway powertrain warranty with an extra option to upgrade to five years and 100,000 miles if you so choose. And just in case we forget who made the project in the first place, the Silverado has been plastered with plenty of Callaway badging to go around.

The price of the whole upgrade hits $15,995. It might be a pretty hefty sum for a performance tune-up, but given the need for beastly trucks like these to have as much power as it can get, it’s probably an investment worth making.
