Expand Your ARB Altitude Rooftop Tent's Carrying Capacity

The ARB Altitude Roof Cross Bar Kit is a purpose-built accessory designed to maximise the utility of your ARB Altitude rooftop tent. By adding a set of robust cross bars to the tent’s integrated roof rails, this kit allows you to securely transport additional lightweight gear above your tent—ideal for overlanding, touring, and extended camping adventures.

How the ARB Cross Bar Kit Enhances Your Setup

When a rooftop tent is installed, available roof space for extra cargo is often sacrificed. The ARB Altitude Roof Cross Bar Kit solves this by providing a dedicated mounting platform above the tent itself. This enables you to carry essential outdoor equipment—such as recovery boards, skis, fishing rods, or compact camping gear—without compromising tent functionality or vehicle storage.

The cross bars are engineered to integrate seamlessly with the Altitude tent’s built-in roof rail system, ensuring a secure fit and even load distribution. The kit is not intended for use with other tents or generic roof racks, making it a precise solution for Altitude tent owners seeking additional cargo options.

Where This Cross Bar Kit is Most Useful

This system is especially valuable for touring and expedition vehicles where multiple types of gear must be carried simultaneously. Typical applications include:

  • Overlanding builds requiring both sleeping accommodation and gear transport
  • Touring vehicles with rooftop tents and limited internal storage
  • Outdoor sports travel, such as carrying skis, snowboards, or fishing rods
  • Camping setups needing extra mounting points for lightweight accessories

The kit allows you to keep your rooftop tent installed while still providing space for the gear essential to your journey.

Key Benefits of the ARB Altitude Roof Cross Bar Kit

  • Designed specifically for the ARB Altitude rooftop tent
  • Utilises high-quality Thule aluminium cross bars with T-slot accessory channels
  • Supports up to approximately 20 kg of evenly distributed lightweight cargo
  • Maintains full tent opening and closing functionality
  • Compatible with a wide range of rooftop accessories (bike carriers, kayak mounts, etc.)
  • Simple installation and removal as needed for different trips

Construction and Technical Details

The ARB Altitude Roof Cross Bar Kit features premium Thule aluminium cross bars, renowned for their strength and accessory compatibility. The bars include T-slot mounting channels, allowing direct installation of compatible mounts and brackets. The kit comes complete with mounting foot clamp assemblies, perimeter securing straps, and all necessary hardware for a secure and stable fit.

Installation and Practical Use

Installation is straightforward, with all components designed to interface directly with the Altitude tent’s integrated rails. The system is engineered to ensure that the tent’s electric opening and closing mechanism continues to operate smoothly, even with the cross bars installed and loaded within the recommended weight limit. For best results, always distribute loads evenly and avoid exceeding the specified capacity.

Solving Real-World Storage Challenges

Rooftop tents are a game-changer for remote touring, but they often limit available roof space for carrying other essential gear. The ARB Altitude Roof Cross Bar Kit addresses this by restoring cargo capability above the tent, allowing you to transport recovery equipment, sports gear, or accessories without needing a full roof rack system. This practical solution keeps your vehicle expedition-ready and your gear accessible, even on extended journeys.
