After turning the Ford Raptor into a six-wheeler, Hennessey Performance decided to do the same for the 2019/2020 Chevrolet Silverado. The result is this, the aptly named Goliath 6×6. The very first example of the new Hennessey truck, which was first previewed back in 2018, is based on the Trail Boss Z71 and comes with a complete 6×6 conversion featuring an all-new rear suspension system along with an extra axle.

In addition, the whole truck gets an eight-inch suspension lift kit, a set of 20-inch Hennessey wheels wrapped in 37-inch BFG off-road tires, new bumpers, a roll bar, LED auxiliary lights and a custom, longer bed. Like all Hennessey’s products, it also comes with a three-year/36,000-mile warranty.


Power is provided by GM’s 6.2-liter V8, which can be further upgraded with the company’s 2.9L supercharger and boost output to 705 HP and 914 Nm of torque.

The first example of the Goliath 6×6 wass sold to Bob Berrard, a noted auto enthusiast and owner of the largest potato farm in the state of Wisconsin. “We are so excited for Bob and greatly appreciate having him as our first Goliath owner,” said John Hennessey.


The tuning specialist plans to build 24 examples of the Goliath 6×6, each sarting at US$ 375,000, which includes the cost of a brand new Silverado.
