There are a number of other upgrades throughout. Hennessey says all three axles can be locked for maximum traction. The suspension is upgraded, and the new 20-inch wheels are wrapped in off-road tires. Appearance-wise the truck gets a style bar, off-road bumpers front and rear, and LED off-road lights in the bumpers and on the roof. Hennessey also offers an optional brake package with six-piston Brembo calipers. It's probably a worthwhile investment, since this truck is probably extraordinarily heavy.
The brake package, and the truck for that matter, aren't cheap. The VelociRaptor 6x6 starts at $349,000, and the brake package adds another $22,000. That price is also greater than the 2016 estimate of $295,000. But for the money, you're getting a highly unusual truck with lots of custom work, as well as a good amount of exclusivity. The company says it's only building 50, and they'll be available to overseas customers, too. Hennessey is building and taking orders now.
