Special Note for Dodge Ram (Classic/DT/DS)

Since Dodge/Ram manufacturered concurrent Ram 1500, 2500 & 3500 models on both new and old body designs, please ensure you select the parts to suit the correct submodel. The year alone may not always be a reliable way to verify your submodel in the case of some Rams, so we encourage you to double check if you have the Classic, or the new shape when making orders for parts that are not the identical between both styles.
