Recheck clearances (sunroof, tailgate) before driving.
Remove bars if you won’t use them for a while to reduce drag and grime buildup.
FAQs: Thule Roof Bars for Roof Rails
1) What exactly are Thule roof bars?
They’re cross bars that attach to your car’s roof (in this case, raised rails), creating a stable base for carrying gear like bikes, roof boxes, skis, and kayaks.
2) What’s special about the Smart Rack XT Aero for raised rails?
It’s a universal, all-in-one kit tailored to raised roof rails: easy install, integrated locks, and an Aero bar option with a T-Track for plug-and-play accessories.
3) Do I need extra adapters to mount accessories?
Most modern Thule accessories slide straight into the T-Track. Some third-party carriers use around-bar clamps—also compatible. Check your accessory’s mounting style.
4) How do I pick the right bar length?
Use our Roof Rack Selector for a vehicle-specific fit. Popular lengths include 118 cm (730402) and 135 cm (730404), but your car’s rail spacing and roof width decide the winner.
5) Will the Aero bars really be quieter?
Yes—their teardrop profile is designed to reduce wind noise and drag versus square bars. You’ll feel the difference on motorways.
6) What’s the load capacity?
Up to 100 kg for the bars, but never exceed your vehicle’s roof load rating or the accessory’s limits. Always follow the lowest number.
7) Is installation DIY-friendly?
Absolutely. The kit includes the tool and locks. Most users finish in minutes. If you prefer, our team can guide you through it.
8) Can I keep them on year-round?
You can, but for best efficiency (and to keep them pristine), remove them when not in use.
9) Do you ship across the UK?
Yes, fast, reliable delivery from Roof Box Shop UK. Need help choosing? Message our experts for a quick recommendation.
10) Are the bars compatible with panoramic roofs or sunroofs?
Often yes, but don’t open the sunroof with bars/accessories installed unless your vehicle manual explicitly allows it
