Ram 1500 and 2500 Canopy Guide: Box Lengths and RamBox

October 26, 2026

FORGED X makes aluminium canopies for the Ram 1500 DT with the 5'7" RamBox box and the Ram 2500 DJ with the 6'4" box, both 2019 onwards. On a Ram, two things decide the fit: the box length and whether the box has RamBox side storage.

Which FORGED X canopy fits your Ram

Canopy	Series	Years	Notes
Ram 1500 DT 5'7" RamBox canopy	DT, fifth generation	2019 onwards	5'7" box with RamBox
Ram 2500 DJ 6'4" canopy	DJ, fifth generation	2019 onwards	6'4" box

Box length and RamBox

RamBox is the lockable storage built into the sides of the box. It makes the inside of the tub narrower and changes the rail profile, so a RamBox ute needs a canopy made for it. Look at the box sides: if there are lockable lids on the outside of the box, you have RamBox.

The Ram 2500 is converted for the Australian market with the 6'4" box. Measure the inside floor of the box from the front wall to the closed tailgate, or send us your VIN.

Solid sides or dog windows on a Ram

For a Ram used for towing and work, solid sides keep gear out of sight.

For a Ram set up for touring, dog windows give access from the side of the box and airflow when camped.

Both options have a glazed lift-up rear door on gas struts, marine-grade 5052 aluminium construction, seals and drainage around every opening for dust and corrugations, and a powder-coated matte black finish.

Weight, payload and roof load on the Ram

Everything you put on a Ram counts towards its GVM: the canopy, racks, drawers, water, fuel, passengers and gear. An aluminium canopy keeps the canopy's share of that number down, which leaves more payload for what you carry. Add up your full setup and compare it with the figures on the compliance plate before you build it out.

On the Ram canopy, the roof takes 150 kg on the move and 300 kg when parked — bars and rack included. That covers a rooftop tent: keep tent and bars inside the dynamic rating when driving, and tent, bedding and people inside the static rating at camp.

Fitting a canopy to the Ram

The Ram canopy goes on with clamps to the factory tub rail, using the hardware supplied — no cutting, no drilling, and nothing permanent. If you sell the ute, the canopy comes off and the tub is as it was.

We fit canopies at 21 Moss Street, Slacks Creek, in Brisbane, or send them on pallet freight to any state for your own fitter. Seals, struts, glass and mounting hardware are kept on the shelf if you ever need a part.

Racks, tracks and locking

Full-length roof tracks are built into the Ram canopy, so bars, platforms, awnings, recovery boards, solar and light bars bolt on without drilling. Yakima track-mount gear fits directly — no adaptor plates — and other common bolt-in systems fit the same track.

Add the optional central locking kit and one press of the factory key locks the canopy with the cab. It plugs into the existing wiring.
