Will upgrading the suspension increase the towing capacity of a jeep? I just bought a boat and I want to tow it with my Jeep. The GTW for the boat and trailer is about 2500 lbs. My jeep is only rated to tow 2000 lbs. I know the tow rating has a lot to do with vechical length because the jeep unlimited has a rating of 3500 lbs because of the extra 10 inches. Does anyone have any personal experince with towing a boat?
