Aluminum Adarac rack system. Was used on my 2014 Ram Quad Cab truck with a 6'4" bed. Very good condition with crossbar padding. Width of the rack is adjustable (at 6' now) as is the length up to 6'4". The supports stand about 25.5" high. I had the rack on a 2014 Ram 1500 with the 6"4" bed. With a little ingenuity the bed mounts could be shortened, mounting them on an 8' bed would be a bit trickier, unless you don't mind drilling holes in the top rail of your bed? Used them for carrying a canoe but we can't lift that high anymore! Email or call or text 406-three two one-two one eight three.
