John Hennessey Explains the Chevy Goliath in Detail

Four wheels are great, and six are amazing. That has been the formula for Hennessey Performance over the past decade. After perfecting the 6×6 conversion process on the Velociraptor, the team turned their attention to the Silverado. It has a base price of $375,000, so our friends at The Fast Lane Truck asked John Hennessey to explain the Chevy Goliath in detail.

If you missed our coverage when it was first released, this build starts at the back of the cab. A new bed is 20″ longer than the original, and it covers their ingenious suspension system. Fabricating a new rear frame allows them to move the factory locking rear axle to the rear. Between it and the transfer case is a custom fabricated middle axle. A pass-through pinion shaft turns an open differential and sends uninterrupted power to the rear. Riding 8″ higher on a custom BDS lift kit, both the front and rear diffs retain their lockers.

Having an open center differential is nice, as it will vary its power left and right depending on conditions. Due to the size and weight, I would recommend the 6.2L V8, but Hennessey will build 5.3L versions like we see here. Due to the complex fabricated parts and time, only 23 more examples will be built. As soon as he cracks the encryption on the late-model truck computers, expect to see the Goliath doing things a Silverado could never dream of.
