If you’re looking for some bonkers
horsepower in your full-size GM-branded SUV, Hennessey isn’t the only game in
town. Callaway has a long history of making various GM machines go fast,
notably the Corvette. We recently talked about Callaway’s beefy 560-hp
(418-kilowatt) upfit for the Chevrolet Tahoe, but for those seeking a bit more
luxury, the same upgrade is available on the GMC Yukon.
Reaching that level of power requires the
6.2-liter V8 versus the 5.3-liter option also available. As with the Tahoe, the
crux of the package involves Callaway’s own superchager system, consisting of a
GenThree supercharger with what Callaway calls a TripleCooled intercooler
setup.
To make the best use of the boosted power,
the Yukon gets a new air intake system and a low-restriction exhaust kit. On
the 6.2-liter V8, those changes yield the advertised 560 horsepower. Callaway
can upgrade Yukons with the 5.3-liter V8 as well, but the result is only 480 hp.
Naturally, with extra power comes a host
of aesthetic changes as well. Whether choosing the SC480 or SC560, buyers get
plenty of Callaway branding with embroidered floor mats, badges for the
interior and exterior, Callaway key fobs, an underhood plaque with a vehicle
identification number, and a documentation package. Perhaps best of all,
Callaway’s performance modifications work with a full factory warranty. That’s
3 years or 36,000 miles on new vehicles, with a 5-year / 60,000-mile warranty
optional.
Speaking of options, Callaway has a host
of extras for the Yukon that add more than just power. Suspension and chassis
upgrades include a Rough Terrain or Handling package, and bigger brakes are
available as well. A pair of Callaway wheel packages are offered in either
20-inch or 22-inch size, and interior upgrades range from a sport steering
wheel and pedals to a full sport interior upfit. Callaway’s website doesn’t
offer specifics on pricing
