Frequently Asked Questions
Will these bars fit if my H3 doesn't have factory roof rails?
These are designed specifically for vehicles with factory roof rails. If your H3 is missing them, this cross bar system won't work without aftermarket rails installed first.
Can I leave these on year-round or should I remove them when not in use?
They can stay mounted, but most owners remove them to reduce wind noise and fuel consumption. The clamp design makes removal quick enough that seasonal storage is practical.
What's the weight limit on these bars?
Load capacity isn't specified in the product data—contact us with your exact cargo setup and we can advise whether these bars are suitable for your needs.
