The 2021 ZR2 Bison features a segment-exclusive Multimatic DSSV dampers, engineered using a spool valve technology.
This allows for improved control and comfort over rough terrain by providing different damping characteristics based on the suspension's position, which means better handling on both on-road and off-road conditions.

A significant upgrade for the ZR2 Bison is its AEV (American Expedition Vehicles) designed front and rear bumpers.
These bumpers not only enhance the truck's aesthetics but also increase approach and departure angles, making it more capable on steep ascents and descents.
The Bison comes with heavy-duty skid plates made from high-strength steel covering critical components like the oil pan and transfer case.
This design minimizes damage to the undercarriage when traversing rocky landscapes, providing a level of protection necessary for serious off-roading.
The truck’s 2.8L Duramax turbo-diesel engine produces 369 lb-ft of torque at just 2,000 RPM.
This low-end torque allows the ZR2 Bison to tackle obstacles with ease, which is beneficial for off-road enthusiasts who encounter steep inclines or heavy mud.
The visibility in the Bison is improved with LED lighting that includes headlights and fog lights.
This enhancement provides a brighter, whiter light for better visibility during nighttime off-road excursions, which can significantly reduce the chances of accidents in low-light conditions.
These tires also feature a 3-Peak Mountain Snowflake rating, meaning they are suitable for severe winter conditions.
The ZR2 Bison's transfer case offers a true two-speed configuration with low range, enabling drivers to harness maximum torque at low speeds.
This feature allows for better control on steep or slippery slopes, enhancing both safety and capability.
The truck has a 5'-1" bed length which is shorter than traditional pickups but is designed for improved maneuverability both on-trail and in urban settings.
This balance is particularly beneficial for off-road use where tight spaces and tricky terrain are common.
An interesting fact about the ZR2 Bison is that it features a 4WD system that can be switched to "4WD Low" on-the-fly.
This allows drivers to change traction modes without needing to stop, which can be crucial during adverse conditions.
The ZR2 Bison incorporates a driveshaft made from high-strength steel rather than the typical aluminum.
This was done to increase durability and reduce damage susceptibility while navigating rough and rocky trails.
The Bison has an impressive approach angle of approximately 30.5 degrees and a departure angle of 23.5 degrees.
These angles are critical in off-roading as they define how steep an incline or decline the vehicle can handle without getting stuck or losing ground.
The vehicle’s weight distribution is optimized with the battery positioned under the floor, which lowers the center of gravity compared to conventional pickups.
This provides enhanced stability during cornering on trails or uneven surfaces.
The ZR2 Bison features a locker for both the front and rear differentials, allowing for maximum traction on rugged terrains.
This feature is especially useful in low-traction situations like mud, sand, or snow, significantly enhancing off-road capabilities.
A notable advantage of the ZR2 Bison's design is its customizable storage options, including under-seat storage compartments.
These compartments are designed to accommodate various tools or gear, making it easier for outdoor enthusiasts to organize their equipment.
The Chevrolet Infotainment 3 system can connect with various devices, providing access to navigation, music, and other applications via smartphone integration.
This feature is particularly useful for off-road navigation and ensuring that drivers remain connected in remote areas.
The ZR2 Bison utilizes high-strength steel for its frame, which enhances rigidity and, in turn, improves safety ratings.
A robust frame is fundamental in absorbing impact energy, providing better safety for occupants during a collision.
Advanced Trailering Technology allows drivers to monitor their trailer from the infotainment system and includes features like an integrated brake controller.
This technology enhances the towing capability of the Bison, beneficial for those who carry extra gear or tow recreational vehicles.
The Bison's front and rear axles are designed with a wider position than standard models, contributing to improved vehicle stability and reducing body roll during sharp turns or off-road maneuvers.
The vehicle's battery system is optimized for high-capacity storage, supporting numerous electronic components including the navigation system, LED lighting, and various sensors, helping to ensure that components receive adequate power during extended usage.
The 2021 ZR2 Bison’s high ground clearance of about 10 inches enhances its ability to pass over obstacles without getting hung up.
This feature is particularly critical for off-road drivers who routinely confront uneven terrain and need to maintain momentum.
