Hey

Does anyone know if the roof rack has a weight limit, and if it does, what it is?
I need to haul some lumber and need to know

Thanks
Joe

Are you talking about the stock roof rack rails or how much the roof can hold? I've had around 300lbs on my Whitson Metalworks rack and the rack itself weighs 70lbs or so. No issues.

If you're asking about the OEM bars, the sticker on it says "Max load 165 lbs evenly distributed".

that 165 probably factors in the fact that it gets top heavy(duh) from loading stuff on top, you can probably have more weight than that but you probably want an after market rack that has more points to distribute the weight to the roof.

So i've read a lot of conflicting information about what the weight limit on the roof of the 4Runner is as i've wanted to add a rooftop tent and the only limit I can find in regards to weight in the 4RNR manual says 120 lbs max. I decided instead of trying to figure it out in the forums and second guessing myself i'd just contact Toyota. The following is my email and their response:

I'm buying a 4RNR that is expected to arrive in two weeks from today. I've seen several with rooftop tents added on the rails on the roof of the 4Runner. Reading through the manual it says not to exceed 120lb in the rooftop luggage compartment. That is the only reference to weight for the rooftop in the entire manual; however, people exceed this weight all the time with their tent setups, especially while they have people sleeping in the tent. Is Toyota saying that 120lbs is all that the roof can carry, OR are they saying that's all Toyotas crossrails will carry, OR i've heard the theory that that is dynamic load limit for when the vehicle is moving but that when its static (stationary) the roof can hold much more. But I have no actual definitive answer and I can't find anything from Toyota that states specially how much the roof the can hold using adequate crossbars to span Toyotas factory installed roofrails.

Conclusion:
Even though people add much more weight than 120lbs in their rooftop setups, Toyota is only willing to claim a 120lb limit on their roof. If you add the extra weight you do so at your own risk and you won't be able to count on Toyota for any warranty work.

Warranty work on a 20yr old 4Runner?!
"Um yes, hello Toyota. I put the biggest RTT money could buy, loaded it to max capacity of 10 people, and now it looks like my roof has a dip in it. Not one occupant weighed over 300lbs.
Hoping I can get this defective roof fixed under warranty."
I think most people understand that anything we do to our rigs is at our own risk, and I would be shocked to see ANYTHING covered under warranty on a 20yr old 4Runner.
I wouldn't put much lumber on the OEM roof bars- how much lumber are you talking? 2 railroad ties was a little sketchy

i saw a picture not to long ago of a guy that put atleast 20-25 sheets of sheetrock up on his roof.

Max load 165 lbs evenly distributed seems pretty clear to me.
Of course, you could try to be like this guy:

Thats all BS, I've had 1000lb of snow on mine! They're indestructible!

I wouldn't recommend going on the freeway with large loads... but you can risk it if you want...



10 sheets, 30+lbs per sheet. Just a few miles of side streets though...

Seriously though, there have been reports of the factory crossbars breaking at the plastic ends, so watch out for that.

Did just fine with this couch on top, for about 8 blocks. Yes, I used straps. It helps to have an understanding of dynamic and static loads, and the importance of very strong sphincter control when driving over small bumps. Also, don't ever do this. I'm sure I exceeded the published limits of both the rack (Yakima) and the 4runner, in addition to breaking several local and state safety laws.

Thanks, best answer yet to the rack loading question. I just want to haul a 90 lb Kay

Nice couch...

I’ve dented my roof in a few times when throwing tires up there, once with bags of soil, and once when I climbed up there.

I’m guessing the roof holds maybe 50 pounds, but it will spring back out as long as you don’t dent it in too much.

If your weight is more distributed on the rails that run lengthwise (not the crossbars) then it should handle much more. People sleep in rooftop tents up there and that’s gotta be several hundred pounds.
