SuperRail Mounting Kits are removable base rails, utilizing SuperBracket type mounting brackets on the frame of the truck and easily removable rails in the bed. Just lift the hitch out, lift the rails off the heavy duty mounting posts and then simply twist the posts 1/4 turn and remove them for a smooth, clean truck bed. Eliminates need to cut bed mats and liners for rail to floor contact. No tools required for complete hitch, rail and mounting post removal.
