What is the weight limit for the roof rack on a Rx350?

The roof rack on most Lexus RX 350 models is rated to carry up to 165 pounds (75 kilograms) of cargo, including the weight of the rack itself. Exact figures can vary by year and roof configuration, so check your owner's manual or contact a Lexus dealer for your specific vehicle.


Understanding the roof load limit


The roof load limit is the maximum combined weight that the roof can safely support, including the roof rack, crossbars, and any cargo. It is a safety rating designed to account for static loading as well as dynamic forces from driving, braking, and turning. Exceeding this limit can affect handling, fuel economy, and the roof structure itself.


Typical limit and what can affect it


For RX 350 models equipped with factory roof rails, the common maximum is around 165 lb (75 kg). Variations can exist between model years and different roof configurations, so it is essential to confirm the exact rating for your vehicle.


To verify the exact limit for your vehicle, use these steps:



  • Check your owner's manual for the section on roof load capacity or weight limits.

  • Look for a roof load or weight limit placard, often located on the driver's door jamb or near the driver's side pillar; note that not all RX 350 models display this number in the same place.

  • If you cannot locate the information, contact a Lexus dealership or Lexus Customer Experience with your VIN to obtain the precise rating for your vehicle.

  • Subtract the weight of the roof rack/crossbars from the total roof load limit to determine how much cargo you can safely carry.


Understanding and confirming the exact rating for your RX 350 helps you plan loads safely and avoid overstressing the roof structure.


Safe loading and operation tips


Distribute weight evenly across the roof


Place heavier items toward the center of the roof and keep the weight balanced side to side to maintain stable handling and reduce wind resistance.


Secure items properly


Use appropriate racks, crossbars, and high-quality straps or bungee cords. Ensure all cargo is tightly secured and cannot shift during transit.


Drive with care


Avoid driving at high speeds, especially in gusty conditions, and always recheck cargo after long trips or rough roads. Remember that the effective limits can change with road conditions and dynamic forces.


Summary


For most Lexus RX 350 models with factory roof rails, the advised roof load limit is 165 pounds (75 kg), including the weight of the rack itself. Because exact figures can vary by year and configuration, always verify the specific rating in your owner's manual or with a Lexus dealer, and load within that limit with proper distribution and secure fastening.
