The mid-engined Corvette dropped today, but if a two-seat sports car isn't what you're looking for, Hennessey has announced they're bringing their Goliath 6×6 package to the Chevrolet Silverado. Starting with a quad-cab Silverado, Hennessey adds an extra axle, 20" wheels, and 37" BFGoodrich offroad tires. The second rear axle isn't just a bolt-on affair, with Hennessey developing an all-new suspension system with optimal geometry. An eight-inch lift helps fit the new wheels and tires, and the 6.2-liter V8 gets a cold air intake to boost horsepower to 450. If that's not enough, Hennessey offers a plethora of options to get almost anything number you can dream up out of the powerplant. The first production model is already sold, and Hennessey plans to build 24 more.
