Is This 700-HP GMC Super-Truck Wild Enough to Battle Ford’s Raptor?

For some GM buyers, the Sierra Denali may not be excessive enough.

GM’s flagship luxury truck is the Sierra Denali, at least until the electric Hummer emerges. It’s impressive. It’s excessive. But for some — i.e. people who have a Ford F-150 Raptor lurking at the house down the street — the stock Sierra Denali may not be enough. For that person, there’s famed tuner Hennessey Performance Engineering. The Texas-based shop has come to GM’s top-shelf pickup to offer the “Goliath” package.

The Goliath package takes GM’s standard 6.2-liter V8, offering 420 horsepower, and adds a 2.9-liter supercharger and the upgrades needed to spit out a total of 700 horsepower. The package costs $26,995 and comes with a three-year/36,000-mile limited warranty.

Buyers can add an optional Goliath Off-Road Stage 1 package, which includes a six-inch lift kit, 35-inch tires, 20-inch Hennessey wheels and a Goliath front bumper for $14,950. Hennessey will also fit a Goliath diamond stitch interior, a Goliath ram air hood, a Goliath rear bumper, a stainless steel Cat-back exhaust, and Brembo front brakes a la carte. Go all-in on a hulking, fire-breathing Goliath Sierra Denali, and it’ll cost well north of $100,000 in total.

One place where you could save some money is on the truck itself. You don’t have to begin with a Sierra Denali; the Goliath build is compatible with any 2019-2020 Chevy Silverado or GMC Sierra that packs the 6.2-liter V8. If you don’t need that sweet Denali chrome, the Custom Trail Boss Silverado starts at $46,365 before incentives, about $20,000 less than a loaded Sierra Denali.

You can order the Goliath package on Hennessey’s website — or at any Chevrolet or GMC dealer.
