I have a 97 2500 4x4 it doesn't have the camper package. I installed a 2. 5 in rancho lift. I haul a 9ft 11 slide in and pull a 2 horse bumper pull. I would like to install OEM type overloads, I can't find a aftermarket supplier. DC is way to proud of their OEM springs and parts for the spring install. Can anyone help me with this matter. Kurt
