Installation, Load Limits & Safety

A roof-carrying setup is safe only when the vehicle, rack, accessory, and cargo all suit one another. This category helps you check those limits and interfaces before loading, then install, secure, and recheck the system.

Start with the limits and measurements

• Calculate the effective roof load for a rack and cargo to find the controlling limit and the remaining cargo allowance.
• Measure crossbars, spread, roof clearance, and vehicle height before buying or fitting an accessory.
• Pack a roof box safely with its own weight, vehicle clearance, and the box maker’s instructions in mind.

Install and recheck the exact system

• Use a documentation-led roof-rack installation and recheck workflow; torque, placement, and inspection intervals are system-specific.
• Install a Tesla Model Y roof rack only with the Tesla-approved mounting accessory and the instructions for the exact vehicle and rack.
• Check 2026 Ford Bronco roof-rack installation and load limits, including the manual’s separate moving and stationary entries.
• Install 2025 Polestar 2 load carriers using the door-frame mounts and supplied torque-indicating tool described in its manual.
• Check the Land Rover Discovery versatile roof rack against the correct roof-rail branch, accessory kit, and fitting instructions.

Load and drive with care

• Secure a roof load and adjust your driving for its height, weight, position, and effect on handling.
• Check regional and glass-roof safety without transferring a rule or approval from another vehicle or market.

If an exact vehicle limit, approved rack, mounting position, or product instruction is missing or unclear, pause and get it confirmed by the vehicle or rack manufacturer or a qualified fitter before loading.
