Weight Limit On Roof Rack

The safety factor is 1 5 to 2 depending on the roof rack and fixture style you can find the safety factor in the roof rack instructions.

Weight limit on roof rack. Total weight 40 2 lbs 165 lbs limit 40 2 lbs rack accessories 124 8 lbs available load capacity note insure you include the weight of any other accessories ski bike boat mounts attached to the bars. The maximum capacity of your roof rack system will be dependent on the lowest rated part of the system. The static weight limit when parked can be higher than the dynamic weight. When parked the additional weight of humans and gear in a rooftop tent can be much higher.

We installed a powerful 4 4 full length steel cage roof rack on a mates patrol a few years back and weighed it at at around 60kg. The 165 pound weight limit is very common and applies to a moving load. Your vehicle and roof must have a minimum driving dynamic weight capacity of of 165 lbs 75 kg. Refer to rooftop tent and rack.

So if you have a roof mounted cargo box that has a weight capacity of 150 lbs roof rack crossbars that are rated at 200 lbs and these are on a roof rated at 100 lbs then you cannot load more than 100 lbs. When you can only carry 100kg on the roof fitting a 60kg rack to only be able to carry 40kg seems a bit pointless.
