1UP Roof rack

THE VERSATILE, DURABLE, AND UNIVERSAL ROOF RACK BUILT FOR ANYTHING. Sleek, tough, and built for the view. The only roof rack on the market with the lowest profile and zero plastic components, delivering less wind resistance and long-lasting durability—truly a double win. It attaches to crossbars with 3/8” carriage bolts and security barrel nuts for rock-solid stability. The Flush Mount Kit fits Thule, Yakima, Whispbars, and any crossbars with a top T-slot, giving your setup a clean, integrated look. This is the only Roof Rack that serves a dual purpose, for both the roof and hitch. 3D Models: STANDARD ONE-HANDED BUILT TOUGH — aluminum construction is light, durable & rust proof. EXPANDABLE TIRE CLEARANCE — Fits 3" tires, with expandable clearance up to 5" with our Fat Tire Spacer Kit. LOW PROFILE — Folds down easily with just 2.5" height, the lowest profile of any roof-tray system. BIKE FRIENDLY — rack arms hold only the tires, protecting your bike frame and fork. CROSSBAR COMPATIBLE — works with most crossbar styles for versatile mounting options. VERSATILITY — Easily converts to Hitch-Mounted Rack or Add-On (see replacement parts).
