Product Weight: 60 lbs. Our 6th Gen Toyota 4Runner Roof Rack features a vehicle-specific curved front fairing designed to follow the exact curvature of the windshield and front roof area for a seamless transition, improved aerodynamic efficiency, and reduced wind noise. The rack features CNC-machined 5/16-inch 6061-T6 aluminum side plates, 1/8-inch 5052 aluminum front and rear plates, and eight 1×2-inch 6063-T5 aluminum T-slot crossbars. The curved front fairing is reinforced with 1/6-inch 5052 aluminum support plates for added rigidity. The main mounting brackets are constructed from 1/4-inch stainless steel and paired with CNC-machined 6061 aluminum mounting blocks. Load Rating Static: 600 lbs. Dynamic: 300 lbs. Load ratings are based on the limitations of the OEM roof structure. Reduce cargo weight accordingly during off-road or high-impact driving.
