When you’re gearing up for a weekend on the water or a long drive across the country, it’s good to know your rack can handle it. This complete roof rack system includes two 53" long aluminum WingBar Evo crossbars, giving you a strong and stable base that supports up to 165 lbs (always stay within your vehicle’s roof limit). Whether it’s kayaks, canoes, skis, or a cargo box, the setup is built to hold your gear securely while you focus on the road ahead.
Anyone who’s driven with a rack knows how wind noise can get old fast. The WingBar Evo design uses an aerodynamic crossbar profile and split rubber strips in the top channels to help cut down on wind noise and vibration while driving. The strips also stay in place after mounting accessories, so you don’t need to trim or fuss with them. The result is a quieter ride that doesn’t drown out the conversation or music.
Getting a rack on a vehicle without factory rails can be intimidating, but this setup makes it straightforward. The system includes four Evo Clamp feet and a custom fit kit designed specifically for installation on a naked roof. It’s built for a precise, secure fit that feels solid once everything is tightened down, so you can load up and go without second-guessing the setup.
If you’ve already invested in carriers or boxes from your favorite brands, you don’t have to start over. These bars are compatible with most bike, watersport, snow, and cargo carriers that mount in the top channels or clamp around the bars. That flexibility means one rack can handle all kinds of trips through every season—just swap out the attachments as needed.
When you park at the trailhead or stop overnight during a trip, it’s easy to add protection for your gear. The crossbars and channel-mount accessories can be locked using Thule’s One-Key System (sold separately), helping deter theft and keeping your equipment secure when you’re away from the vehicle.
