The 2020 Chevy Silverado 1500 6×6 by Hennessey Performance is called the Goliath. The truck you see here is number one of 24. It’s a very limited run of customized trucks, and each truck retails for about $400,000. Here is exactly what makes this customized truck the biggest and baddest Silverado of them all.

Chevy Silverado 6×6

If you want to get noticed on Rodeo Drive, or traverse a muddy or sandy terrain – this fully functional Silverado 1500 6-wheel-drive truck may be just the ticket. Naturally, this very unique truck will come at a steep price.

Hennessey Performance started with a new Silverado 1500 crew cab 4×4. They cut and extend the rear frame section to allow for a third axle. The rear suspension setup is all unique to this truck. The whole truck gets an 8-inch lift and larger wheels and tires.

The rear-most axle is basically the stock rear axle from the donor truck. The middle (“rear”) axle is a new unit with a pass-through differential with gear drive that sends power to the back. The whole truck is nearly three feet longer than a stock truck, and the bed gains about two feet in length over stock.

This particular truck has a stock 5.3-liter V8 under the hood. It still has the stock power output of 355 hp. This is due to the fact that GM has locked down the new truck’s ECU/computer that prevents aftermarket companies from tuning the engine for more power.

This truck has an upgrade brake package that provides adequate stopping power. The 6×6 Goliath weighs about 2,000 lbs more than a stock 4×4 crew cab.
