This may seem like a silly question. I have a 03' 3500 with 83,000 miles, and OEM original shocks on her. I have been thinking about changing them, but for some reason I am not sure they need it. We use the the truck for pulling our 12,400 lb trailer, and that amounts to about 10,000 miles or less a year. This year so far it has only been about 1,500 miles. I have not had any unual tire wear, we don't normally use to haul anything heavy any other time. They are not leaking, and the ride appears to be about the same! So, what say ye good fellows of TDR?
