IMPORTANT: If you are using an Andersen Ultimate Connection with a Rota-Flex Pinbox, we REQUIRE you to use a Rota-Flex Lockout Kit to prevent damage to the hitch and/or tow vehicle. It also keeps the rubber pad in your Rota-Flex pin box from shifting over time.

If your Andersen Ultimate Connection (standard or toolbox version) will be installed on a 2015-2019 model of a GMC or Chevy Truck without an OEM puck system, we suggest pairing it with the Full Bed Support System. This helps prevent warping that may result from torque forces, and fastens to the frame beneath the rearward bed saver rail.

If you need to change the height of your gooseneck ball, you may need a coupler tube to extend the connection of the Ultimate Connection so it can attach to the gooseneck ball. Refer to the Coupler Tube Chart to find the right size Coupler Tube.
