AEV’s Colorado Jack Base provides 3-1/2 inches of additional lift height to the Colorado’s factory bottle jack – allowing tires of up to 35″ to be changed with ease and stability. Many people don’t realize that the stock jack won’t work to safely change larger tires (even a 33” tall tire) until it’s too late, leaving them stranded on the side of the road or even worse, on the trail. The Colorado Jack Base has a substantial, 10.5″ wide footprint to provide better stability in off-road and soft soil conditions when using the factory jack or even a Hi-Lift jack. It can also double as a wheel chock in order to prevent a disabled vehicle or trailer from rolling. When not in use, the Jack Base stows neatly into the Colorado’s under-seat rear storage compartment found in both extended and crew cab models.
