The Multi-Link Live Axle suspension system uses a combination of upper and lower control arms to isolate the wheels from the chassis, providing greater stability and comfort.
- Self-Levelling Air Suspension: This technology allows the air pressure in the suspension to adjust automatically, ensuring optimal ride height and stability regardless of load or terrain. Self-Levelling Air Suspension can help maintain a consistent ride height, even in extreme off-road conditions.
- Active Dampening Suspension: This system uses electronic valves to adjust the suspension’s damping rates in real-time, providing optimal control over wheel travel and body motion. Active Dampening Suspension can help improve on-road handling while maintaining off-road stability and control.
Each of these solutions can be tailored to suit the GMC 2500 AT4’s capabilities, providing a unique blend of on-road comfort and off-road prowess.
Wheel Configurations
The choice of wheel configuration on the GMC 2500 AT4 plays a critical role in influencing handling and traction. Two main options are available: 17- or 20-inch wheels. While both sizes offer excellent performance, there are key differences to consider:
The 17-inch wheels provide a better balance between on-road comfort and off-road capability. They are wider, which improves traction, and have a higher sidewall, which helps to reduce damage from off-road obstacles.
The 20-inch wheels, on the other hand, are narrower and have a lower sidewall, which can result in reduced traction and increased damage risk. However, they do offer improved on-road handling and a more aggressive appearance.
Trim Level Comparison
Here is a comparison of the key features and benefits of various 2026 GMC 2500 AT4 trim levels:
| Trim Level | Off-Road Capabilities | Additional Features |
