Designed and engineered specifically for Land Rover Defender, the cross bars are optimised for aerodynamic performance and to minimise wind noise. Manufactured from anodised aluminium for premium appearance, they are easy to fit with torque control tool included. The pre-set positioning ensures the cross bars are fitted to the roof rails in the optimum position for weight distribution and dynamics, providing you with additional confidence in safe roof carrying. Lockable for enhanced security, they include a T-track design to facilitate installation and removal of roof carrying accessories. Material tested to withstand harsh environments including corrosion resistance. City Crash tested and also ISO-PAS 11154 compliant. When fitted, the maximum carrying capacity of the cross bars is 94kg. For 110 only. Roof rails required for fitment. Consideration should always be given to vehicle's maximum roof load capacity to ensure this is not exceeded. Objects placed above the roof mounted satellite antenna may reduce the quality of the signal received by the vehicle and could have a detrimental effect on the navigation and satellite radio systems, if fitted. Items carried on the roof may restrict the opening of the vehicle?s sunroof when fitted. Care should be taken when opening the roof to avoid collision with any items fitted above the vehicle.
