Was wondering if anyone has replaced the stock shocks on a 2011 2500HD ? I know its a rough ride without any weight in the bed and I really don't want to drive around all summer with the added weight to soften the ride. I have already dropped the air pressure some in the tires. Maybe there are some other fixes people have done. Truck rides like a cadillac when towing, but that is only 10% of the time. Thanks for any help.
