Hold your hats folks. This “Concept Truck” will blow your cap right off your head and you can see it in person at this year’s 2021 SEMA Show.
Unveiled a day before the 2021 SEMA Show was set to kick-off, the Chevy Beast is a one-of-a-kind concept truck that showcases the extreme side of off-roading. It features a bevvy of production parts taken from the Chevrolet Performance Parts bin, including a 650-horsepower Supercharged 6.2L V8 engine.

The Beast is based on a short bed Silverado chassis that has been modified for off-road racing duty and includes a tubular safety cage system. A unique long travel suspension system with a five-link rear suspension was also adapted for the vehicle. Chevy says the independent rear suspension is a “concept” but we know better. This is probably a hint of what’s coming down the line for the Silverado someday soon. The Beast has a widened 91-inch track for more stability, too.

The Beast is powered by a Chevrolet Performance LT4 6.2L Supercharged crate engine producing 650-horsepower. That engine is mated to a 10L90 10-speed automatic transmission and routes that power through a two-speed transfer case.
Getting all of that power to the ground are 37-inch tall off-road tires mounted to 20-inch wheels equipped with a bead lock system. For good measure, Chevy has also thrown in its Brembo Big Brake upgrade kit.
Inside are four Recaro performance seats and a pair of 7-inch LCD screens that communicate vehicle data, including pitch and roll angles, to the driver.

“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.”
