About these items These roof rack crossbars expand vehicle cargo space for transporting luggage racks, cargo boxes, surfboards, bikes, skis, camping gear, and other oversized items. The three configurations are designed for different roof structures and vehicle mounting requirements. Made from 6063-T6 aluminum with reinforced internal ribs, the crossbars combine a lightweight structure with resistance to rust and corrosion. The mounting components are designed to provide a secure connection while helping protect the vehicle roof. The crossbars include locking systems with keys for added control during travel. Rubber or nylon mounting pads help reduce contact between the rack and vehicle surface, while the aerodynamic bar design helps limit wind resistance and operating noise. Installation requires no drilling and can be completed by adjusting the mounting feet or metal brackets to match the vehicle. Each configuration has specific roof measurements, so checking the compatible rail spacing or gutter dimensions before purchase is recommended. The lineup covers raised side rails, grooved side rails without gaps, and vehicles without side rails. Load capacities range from 70 kg to 100 kg, providing different options for everyday cargo transport, road trips, outdoor recreation, and vehicle storage needs.
