Based on the chassis of a short-bed Silverado and powered by a supercharged 650 hp (659 PS/485 kW) LT4 crate engine, “The Beast” is Chevrolet’s demonstration of everything Chevy Trucks and Chevrolet Performance components can make.

“The Chevy Beast concept takes the popularity of high-performance off-road trucks to the next level,” said Jim Campbell, GM U.S. vice president of Performance and Motorsports. “It’s a vision for a new dimension of Chevrolet Performance capability from a brand that’s been pioneering performance and supporting customer personalization for more than 50 years.”

The automaker’s designers started with the short-bed Silverado and modified the chassis for high-speed desert running. The frame was shortened and a custom-designed 4130 chromoly tubular safety structure was integrated to the frame.

Keeping it all comfortable off-road, is a concept long-travel, off-road suspension system that was created specifically for this vehicle. It includes a five-link rear suspension and a widened 91-inch track, which contribute to more stable handling and optimal control.

“There’s nothing else like The Chevy Beast,” says Jeff Trush, GM program manager, Pace Car and Specialty Show Vehicles. “It delivers a ton of performance and capability, which makes it adept at conquering rough terrain — and it flat-out flies in desert running.”

The 6.2-liter supercharged V8 engine is paired to a 10L90 10-speed automatic transmission that sends torque to a two-speed transfer case. It sits on 20-inch Beadlock wheels that are wrapped in 37-inch off-road tires. It also gets a Chevrolet Performance Big Brake Upgrade System.

The team then topped it all off with a lightweight body that was designed to also be as small as possible on the frame. With virtually no overhangs, the team was able to maximize approach and departure angles when off-roading.

Still, The Beast contains a pair of spare tires mounted in the bed, which is left open to prevent it from trapping dust. Inside, meanwhile, the custom cab has a minimalist, functional design that features four Recaro performance seats with four-point harnesses, as well as a pair of seven-inch LCD screens that monitor vehicle functions and performance data, including pitch and roll.

Along with the Beast, Chevrolet will also show off a number of trucks and the SuperMatic 6L80-E 4WD Transmission designed for off-road project vehicle builders. The six-speed automatic transmission is designed specifically for 4WD applications and has the same 650 lb-ft (881 Nm) torque rating as the RWD 6L80-E transmission. It also works with the brand’s Connect & Cruise Crate Powertrain System for compatibility with LS crate engines.

All will be visible on the SEMA show floor at the Las Vegas Convention Center from November 2-5.
