Notes

  • A 2-1/2 in receiver takes a 2-1/2 in square shank and a 5/8 in hitch pin, per CURT/Lippert's class and pin guides.
  • Rated weights depend on the specific hitch; the class figures are the maker's typical ranges.
  • No CAD file: the maker publishes only overall sizes, and a plain box or cylinder is not useful design geometry. The table is the published data; parts with real geometry have their own pages.
