Hennessey’s latest 6×6 truck conversion has to be one of the most spectacular so far.

Based on the all-new Chevrolet Silverado, the suggestively named Hennessey Goliath 6×6 is no doubt the biggest, baddest custom Silverado made so far and features one additional axle complete with 20-inch wheels, BFG 37-inch off-road tires, and brakes.

That’s not all, as it also gains an all-new rear suspension, 8-inch (203-mm) lift kit, a custom 6×6 truck bed, and a 450 HP engine upgrade for the 6.2-liter V8 thanks to a cold air intake and stainless steel exhaust.

Hennessey also throws in new front and rear bumpers, a rollbar upgrade, LED lights, as well as Goliath 6×6 and Hennessey graphics. The result is a truck that’s much more exclusive than the Mercedes-AMG G63 6×6, as Hennessey will only build 24 of these six-wheeled pickups.

It’s slightly more “affordable” than the G-Wagen, though, if we can use this term for a truck that starts at $375,000. Still, you can make it even more expensive if you opt for a 2.9L supercharger upgrade that takes the V8 to 705 HP and 675 lb-ft (914 Nm) of torque.

This particular truck you see in The Fast Lane Truck’s video costs around $400,000 and it doesn’t even have the supercharger upgrade. The video includes a first contact with the Goliath 6×6 in the presence of company owner John Hennessey, who obviously offers plenty of inside information on his latest creation.
