Essential for self driving travel: A comprehensive guide to selecting and using roof crossbars

When preparing to install a roof box or bike rack, many car owners discover that the roof rails are the foundation of the entire system. Without them, neither the roof box nor the bike rack is practically a thing. So, what exactly do roof rails do? How do you choose one? What precautions should be taken during installation? Let's take a comprehensive look.

What are roof rails?

Roof rails are load-bearing devices fixed to the roof of a vehicle, used to support roof boxes, bike racks, kayak racks, and more. They act as a foundation, determining the roof's ability to expand.
🚗Core Function:  They provide load-bearing support and a secure mounting point.
🚗Useful for:  Long-distance road trips, camping trips, cycling, and other activities.

Why do you need roof bars?

①Extend roof space:  When the trunk doesn't fit, cross bars transform the roof into a new storage platform.
②Versatility:  Not only can they be used with roof boxes, but they can also carry bicycles, surfboards, kayaks, and more.
③Security:  Compared to temporary lashings, cross bars ensure stable and secure storage, ensuring safe driving.

What factors should I consider when choosing a roof rail?

🚕Load capacity:  Generally 40–100 kg. If you're traveling with a lot of gear, we recommend choosing a higher-load capacity model.
🚕Material:  Aluminum alloy rails are lighter and more durable; steel rails are stronger but heavier.
🚕Installation:  Quick-release clips are more convenient; bolt-on installation is more secure.
🚕Wind noise reduction:  Streamlined rails reduce wind noise and fuel consumption during driving.
🚕Compatibility:  Verify that the rails are compatible with the interfaces of your roof box or bike rack.

Installation and Usage Notes

①Before installation, confirm whether your vehicle supports crossbars to avoid dimensional discrepancies.
②The crossbar spacing must meet the installation requirements of the roof box or rack.
③Check the fixing screws regularly to prevent loosening due to prolonged use.
④When loading, distribute the weight evenly to avoid uneven loading.
⑤Observe the maximum load capacity limits specified in the vehicle manual.
