Cargo box on original cross bars?

Searched the forum but nothing came up about this:
Can you put a cargo box (for skis etc.) on the standard crossbars? They look a bit thin and flimsy, but my owner's manual does not mention cargo boxes, only the standard warnings about weight limits, precautions when transporting long items (boats, plywood sheets, etc).

I have however seen translated manuals for the same vehicle, that explicitly warns against using cargo boxes on standard cross bars.

I'm confused . What does your owner's manual say?

Cant imagine why the bars would be there if you cant use them.

Ive never hauled a cargo hauler, but Ive had a mattress set, Christmas tree's, wood, potato guns, etc up there. Never had any issues.

I drove from Birmingham Alabama to Savannah Georgia with a mattress and box spring strapped to the top once.

I would love to see a potato gun large enough to be mounted to the top of a jeep.

No problem. The cargo box's are flimsy and a good match for the flimsy roof rack. I have a Thule and haul ski's a bunch. You might want to get one of those step-ladders for your tire so you don't have to stand on rear seat.

Also, studies have shown you will get better mileage with the box mounted backwards. It looks goofy but is aero-correct. Expect to lose a mpg or two if its windy.

They just don't look flimsy, they are flimsy. IMO, the stock crossbars are a joke, nothing more than that. IIRC they have a 100lbs load rating, but I've strapped no more than 50-60lbs worth of timber on them right on the side next to cargo rails - and they still bent pretty severly under the load. Dunno if the 4.0/5.2 crossbars are any better than the niner version, as far as I know the roof rails and crossbars are a bit different on the niners.


I've seen many people use ski boxes on the stock rails/ crossbars, if they spread the load from one side to another fairly evenly on both of the bars it should be ok.

I've hauled a 200lb+ 4x8 popup ice shack on mine and didn't have any issues.

I've put 10 or 12 pressure treated 4x4s on mine. Seemed to be fine but I was only driving a couple miles. I would think a roof box would be okay. You can steal extra bars from junkyard ZJs if you need a little more support. Saw a pic of a guy on here that had four of them.

I made one with 2400 cubic inch reservoir, a custom-made-for-potato-cannons trigger, and a 7 foot long rifled barrel. Pressurize the tank to 70-80 psi, and pull the trigger. Just make sure you're standing waaaay back. It'd shoot a frozen potato through a 3/4" piece of solid oak. I'd love to mount that to a roof

I have a Yakima cargo box that I use on my rig. I tried it first with the stock cross bars and found out that they were too flimsy so I used some Thule cross bars that I had laying around the garage. They were much better than the stock ones. I went for the Yakima cargo box rather than the Thule because it was built better and didn't move around in the wind as much as the Thule.

Thanks for all input.

Back to the original question: Does the original US owner's manual mention cargo boxes at all? Mine doesn't, but in Europe some translated ones expressly prohibits the use of cargo boxes on stock cross bars.

Checked the owner's manual on my 93. No mention of cargo boxes specifically but it does talk about sheets of plywood and small boats. Can't imagine that a small boat would be okay but not a cargo box.

I put my yakima up there all the time, had to drill the crossbars cause they're a strange size though. Put sheets and sheets of 3/4 ply up there for year too. The 10 pieces of 2" sch 40 pipe finally broke em though.

Just as in my owner's manual, in English.

Funny thing is that some ZJs in these parts came with Swedish owner's manuals, where cargo boxes on original crossbars are expressly forbidden.

^- that's like the sticker-instructions on aluminum 6-step ladders I bought from Biltema, there are special mentions "Sweden only" to avoid certain things ..and I am not kidding..
