What hitch pin do I need to attach my rack to my vehicles receiver hitch?

  1. There are two types of hitch pins, Threaded or Smooth, available in standard or locking.
  2. Threaded hitch pins are the same size (1/2” x 13 Threads Per Inch) for 1-1/4” and 2” receiver racks. They are available in standard (provided with the rack) or locking (available from our website).
  3. Smooth hitch pin is ½” diameter for 1-1/4” receiver racks and 5/8” diameter for 2” receiver racks.
  4. All smooth hitch pins sold now are locking. Older racks using a smooth hitch pin had a hole at the end of the smooth hitch pin for a keyed padlock (also provided at that time).
