4x4 Cross Bars

Factory rails on your 4x4 already give you the mounting line. Cross bars complete it. These bars clamp across the rails your vehicle left the factory with, turning them into two fixed points for a roof box, a bike carrier, an awning or a roof tent. The range is grouped by make and model, from the Discovery and Juke to the XC60 and A3, so the clamp matches the rail profile you have.

How do you fit cross bars to factory 4x4 roof rails?

Identify the rail style

Factory rails come in two broad styles. Flush rails sit tight against the roof with the fixing hidden underneath. Raised rails leave an open gap you can pass a clamp around. Each bar set is made for one of these, so identify yours before ordering.

Set the spacing for the load

Position the bars for what goes on top. Roof boxes and tents state a mounting range, bike carriers want the bars far enough apart to hold the frame steady, and a wide load sits calmer with the bars spread out.

Locking and security

Where a set includes a lock it is named on the product page. Locking is worth having if the bars stay on the vehicle between trips or the vehicle parks in public overnight. Check the description for the sets that carry one.

Frequently Asked Questions

Do 4x4 cross bars fit flush roof rails? ▼

Each listing names the rail type it suits, flush or raised, and the clamp design that goes with it. Check the rail style on your vehicle against the clamp type named on the listing, then open the model page for your 4x4.

Can I mount a bike carrier on 4x4 cross bars? ▼

Yes. Bike carriers clamp around the bar, which is exactly what cross bars are there for. Set the bar spacing to suit the frame length and check the mounting range printed in the carrier instructions.

Do I need roof rails to fit 4x4 cross bars? ▼

Cross bars clamp to rails, so a vehicle with factory rails is ready for them. A 4x4 starting with a plain roof takes rails from our 4x4 roof rails page first, or the complete kit pairing both parts.

How do I check cross bars fit my 4x4? ▼

Open your model page from the block above and match the year range to your V5, since rail design changes between generations.

Is delivery free on 4x4 cross bars? ▼

Yes. Delivery is free to the UK mainland and Ireland, and cross bars usually dispatch within 48 hours. Next Day Dispatch is available as a paid upgrade at checkout.
