You did not buy that deluxe RV trailer to sit on cinder blocks by the garage all year. You bought it to hitch up to your pickup truck and tour the country, experiencing the beautiful landscape one mile after another. Put your mind at ease with every mile of your journey by installing your 5th wheel hitch the right way with CURT 5th wheel brackets. CURT semi-custom 5th wheel brackets are designed to work with CURT universal base rails when installing a 5th wheel trailer hitch. The semi-custom brackets fit on certain trucks that are unable to use parts from the universal installation kit due to limiting obstructions on the underbody. Together with the universal rails, the semi-custom brackets create a solid attachment point for your 5th wheel hitch. Like our custom 5th wheel brackets, CURT semi-custom brackets come with a liquid A-coat finish, making them resilient to rust and scratching. These particular semi-custom 5th wheel brackets are designed to be used in combination with CURT #16100 or #16200 rails and offer a vehicle-specific fit for certain Dodge Ram 1500 trucks (see application info to verify fitment).
