So I have an odd question. I have a new 2021 Overland. Because we drive a great deal on backcountry mountain roads with steep hills in the winter. I have always used chains on the front wheels for stopping and steering on the ice. But I just drove the Overland home and noticed that there is something (part of the suspension?) that sits about an 1 1/2” above the tire. What is it? And any thoughts about chains? Putting them on the rear doesn’t help for steering / stopping. Any help welcome.
