How to Determine What Type of 5th Wheel Rails are Installed on Truck


I recently purchased a 2006 F-350 Super Duty DRW. There is an existing set of above bed rails. However, I cant see any indication of a brand. How could I find out which sliding 5th wheels will fit the existing rails?


Expert Reply:

Most likely, the fifth wheel rails already installed on your 2006 Ford F-350 are above-bed, industry standard rails. Most manufacturers (with some exceptions) use these types of rails for their fifth wheel hitches to install into. Each manufacturer makes their own brand of rail kit, but these types of rails will essentially have the same dimensions so that they can accommodate fifth wheel hitches from different manufacturers.

I have attached an image that labels the dimensions of standard rails. I recommend comparing it to what you have to ensure that the rails on your truck are indeed industry standard.

If you find this to be the case, a sliding fifth wheel hitch like the Pro Series 20K # PS30121 will be a great option. This hitch will give 10 inches of additional travel for making sharp turns and a 20,000 pound towing weight capacity. It also features a nice double jaw to completely surround the trailer's king pin for a secure connection. I have attached a video demonstration on this product along with a link that will take you to our available selection of fifth wheel hitches that will fit your truck.

If you have a particular fifth wheel hitch in mind, I will be happy to confirm for you if it is compatible with industry standard base rails.
