The weight ratings are likely due to the stated ROOF capacity of the vehicle, not necessarily the rack. Be careful overloading your rigs!
Where do you see the roof capacity stated? I'll look in the manual later but I didn't trip across this before.

Ah! I think you're right about that. When I google "2025 4runner roof load rating" it says 165 lbs dynamic. And I presume you have to subtract the weight of the rack from that. So my thought of using the roof of the 4runner with a 6' length rack as a semi-substitute for a pickup bed is probably a pipe dream. I could probably barely carry 100lbs before reaching the roof limit. Am I looking at that correctly?

Edit to add, @Rellims above, found 135 lbs listed in the manual so that's probably more official than my google search results. And even worse.

Edit #2: when I look at the Prinsu Pro website for the 2025 4runner full-length rack (they don't give the weight of the rack itself), they strongly imply the 1200lb static strength of their rack itself overcomes the roof limit. Are they right, or are they using dangerous "marketing speak." If the roof itself cannot be reinforced by the construction of the rack, there's no point spending money on any rack with more that ~150 lbs static.

I just want to confirm the 135 lb number Rellims gave above. From p204 of the manual:

"4WD models: Do not exceed
135 lb. (62 kg) cargo weight on
the roof luggage carrier. Place
the cargo so that its weight is
distributed evenly between both
cross rails."


I wonder if Toyota's determination of 135 lbs has more to do with changing the center of gravity of the vehicle with the top-heavy weight, and the vehicle becomes progressively more unstable as more weight above that amount is added to the roof when cornering (or swerve to avoid hitting something), more than it has to do with the strength of the roof (which, after all, doesn't flatten into a pancake after a rollover accident).

My take is that's the limit on the stock rails and crossbars which are pretty weak. I have a Sherpa on my 2021 and it definitely can handle more than that. The bolts and mounting on the 4Runner are pretty stout built.
