Two of GM’s new off-road performance focused pickup truck models – the 2024 Chevy Colorado ZR2 Bison and the 2024 GMC Canyon AT4X AEV Edition – basically share the same suspension configuration between them, making both stand tall with an identical 12.2 inches of ground clearance.
GM Authority asked The General whether there is any difference at all between the suspension of the 2024 Chevy Colorado ZR2 Bison and the 2024 GMC Canyon AT4X AEV Edition, and learned from a GM representative that there is in fact one small difference.
While the Chevy Colorado ZR2 Bison and the GMC Canyon AT4X AEV Edition have nearly interchangeable suspension design, the two trucks differ in the use of the Multimatic jounce control dampers. Specifically, the Bison equips the Multimatic dampers as standard, while this element is available as an option on the Canyon AT4X.
Multimatic jounce dampers create a secondary suspension effect using nitrogen-charged bump shocks. The jounce control dampers boost compression damping and controlled rebound, increasing suspension performance.
In practical terms, the Multimatic jounce control dampers help with suspension stability in extreme overlanding conditions. This includes more stable off-road towing, better rock-crawling performance, strongly increased stability and handling on rough terrain, and prevention of suspension bottoming.
The mid-size 2024 Chevy Colorado ZR2 Bison adds even more off-road features to the already trail-capable Colorado ZR2. The truck sports an AEV heavy-duty front bumper with a winch mount, an AEV rear bumper and AEV fender flares. It rides on AEV 17-inch beadlock-capable wheels wrapped in 35-inch OD Mud/Terrain tires.
The Bison’s suspension is upgraded with the aforementioned Multimatic front and rear Jounce Control Dampers as standard, plus standard DSSV dampers. If the lift isn’t enough to clear every obstacle, a Boron steel skid plates and rocker protectors shield vital parts of the Colorado ZR2 Bison’s underside.
For its part, the 2024 GMC Canyon AT4X AEV Edition similarly upgrades the “regular” Canyon AT4X. Designed in partnership with American Expedition Vehicles (AEV), it boasts stamped steel front and rear bumpers. Five ultra-high strength, hot-stamped Boron steel skid plates protect the front approach, suspension and steering gear, the transfer case, the fuel tank, and the rear differential. It rides on 35-inch Goodyear Wrangler Territory MT tires wrapped around exclusive AEV beadlock-capable Salta wheels.
In addition to sharing nearly the same suspension, the 2024 model year Colorado ZR2 Bison and Canyon AT4X AEV Edition are motivated by the same powerplant. Each truck model cradles the turbocharged 2.7L I4 L3B gasoline engine as its only available engine choice, specifically the Turbo High-Output variant rated at 310 horsepower and 430 pound-feet of torque.
For both truck models, engine power reaches the axles via the second-gen GM eight-speed automatic transmission. Structure for both is provided by the updated GMT 31XX-2 platform, and both are designed with a 38.2-degree approach angle, a 26-degree departure angle, and a 26.9-degree breakover angle.
Production of both vehicles will take place at the GM Wentzville plant in Missouri.
