Callaway wants to boost your Suburban (and other GM trucks and SUVs) to 602 hp


What, 420 horsepower hauling your 6016-pound Chevrolet Suburban around just not enough? Callaway Cars would like a moment of your time, and maybe $24,995-and-up of your money, to solve your problem. The estimable tuner from Old Lyme, Connecticut has developed a supercharger package for your new Suburban and other General Motors trucks and SUVs. How does 602 horsepower sound? Imagine how you could rocket to the head of the kid pick-up line at school.


Upgrades are available for 5.3-liter and 6.2-liter V-8s in the 2021–23 Cadillac Escalade, 2021–23 Chevrolet Tahoe and Suburban, 2022–23 Chevrolet Silverado 1500, 2021–23 GMC Yukon and Yukon XL, and the 2021–23 GMC Sierra 1500. The 602-hp figure applies to the 6.2-liter engines; the 5.3 can be boosted to 520 horses. The new GMC Sierra AT4X is also eligible.

Callaway’s Eaton superchargers are triple-cooled and controlled by Callaway’s engine management program. The vehicles, when driven conservatively, deliver “near stock” fuel economy, Callaway says. Intake and exhaust system modifications are included. In addition, “tasteful aesthetic upgrades, observing Callaway’s signature sophisticated approach,” are part of the deal. “Standard equipment includes Callaway Badging, interior and exterior, Callaway Carbon Mid-Engine Covers, Anodized Door Sill Inserts and Key Medallions. Plus, an Authenticity Documentation Package certifies that your Callaway is ‘the Genuine Article.’”

The upgrades are called, appropriately, the SC520 and SC602. They are available through Callaway’s authorized GM network of dealers. Pricing starts at $24,995 and includes a limited powertrain warranty, with optional coverage to 5 years/60,000 miles.
