The AMP Research BedXtender HD Max (74840-00A) is a folding aluminum truck-bed extender for the 2019-2023 Ram 1500 (fifth-generation DT body), finished in matte silver. Flipped out over the lowered tailgate it adds up to 2 feet of usable cargo length; flipped inside with the tailgate closed it corrals smaller loads against the bulkhead.

Why owners choose it

  • Adds up to 2 feet of usable bed length over the lowered tailgate — turns a 6.5 ft bed into more than 8 ft of cargo space.
  • Supports up to 400 lb when extended over the lowered tailgate.
  • Tubular 6063 T-6 aluminum frame with rigid nylon uprights, powdercoated matte silver.
  • U-shaped 'Max' cage corrals coolers, gear, and tools so loads don't shift in the bed.
  • Reverses inside the bed with the tailgate closed to contain smaller items.
  • Removable when you need a fully open bed.

What's included

Includes the BedXtender HD Max unit and the vehicle mounting hardware. Installation takes about an hour in a home garage or driveway; some drilling may be required. If you run a tonneau cover, order AMP's tonneau cover spacer kit for clearance around the cover clamps.

Fitment

Fits the 2019-2023 Ram 1500 (fifth-generation DT body) with a standard bed. Does not fit RamBox cargo-management beds or the Multifunction (split) tailgate. If your truck is the previous-generation Ram 1500 Classic (sold new alongside the DT), verify the body style before ordering — it uses a different bed extender application.

Which BedXtender is right for you

The HD Max is the U-shaped full-cage design for the most corralled space. The HD Sport is narrower and adds clearance for tonneau cover rails, and the HD Moto is tapered for hauling a motorcycle. This 74840-00A is the matte silver finish; a textured matte black version is sold under a separate part number.
