4x4AT offer a selection of BMW X5 roof racks, roof rails and cross bars to increase the vehicle's payload and functionality. Roof rails fit along the roof from front to back, whereas cross bars are transverse, for affixing cargo such as ladders, timber, cycling racks, canoes, tents or roof boxes. We also stock cross bars for tonneau covers and hardtop roof systems. We offer a professional fitting service for all the BMW X5 accessories we sell, available at one of our UK installation centres, contact us for details.
