The powerfully innovative available MultiPro™ Tailgate combines six convenient functions that help improve loading, unloading and accessing the cargo bed to make light work of any job.
Tackle tough terrain with AT4X front and rear e-locking differentials, which assure both wheels will spin together regardless of the amount of resistance to keep traction in the rough backcountry. They will send power where you need it most in low-traction scenarios like mud, gravel or sand. The lockers will also help give control when ascending or descending steep inclines.
Multimatic™ DSSV dampers feature three separate spool valves to control damping and three connected chambers for fluid flow, delivering premium control and comfort on road, as well as robust performance during off-road adventures.
AT4X is equipped with a specific off-road chassis and tuning, including Terrain mode, ideal for low-speed, off-road conditions. This mode gives you extreme control and is precision-enabled for one-pedal rock crawling, using only the accelerator.
