The Goliath uses a 2019 Chevrolet Silverado Trail Boss Z71 as its base.
Hennessey then adds the second rear axle with the required brakes, 37-inch off-road tires and all that good stuff.
There's a whole new rear suspension setup, in addition to a four-corner lift that adds 8 inches of ride height.
The bed is custom developed for the Goliath, too.
The Silverado's 6.2-liter V8 is removed and equipped with a 2.9-liter supercharger, and a new exhaust system is fitted to the truck. The new power output is a meaty and ludicrous 705 horsepower and 675 pound-feet of torque.
The price for a 2019 Goliath 6X6 is a hefty $375,000, which includes the cost of the truck.
