In case you’re not familiar, the Chevrolet Silverado Trail Boss Z71 is a supremely robust and capable off-road pickup. Honestly, it’s one of Chevy’s best offerings. That also means it didn’t really need improving. But that didn’t stop Hennessey Performance from taking it to task and turning it into the monolithic Goliath 6×6.
The most obvious upgrade to the original truck is that Hennessey added another axle for two more wheels — and, yes, all six wheels get power from the engine. To compensate for the two extra all-terrain tires, they also gave it a special new off-road suspension, an eight-inch lift kit, and — best of all — a new supercharger on the 6.2L V8 engine under the hood. That engine upgrade means a massive boost to the tune of 705 horsepower and 675 foot-pounds of torque. In classic Hennessey fashion, they’ve managed to take an already great vehicle and elevate it into the stratosphere. The Goliath 6×6 will sell for $375,000.
