Features to know about

Avoid Awkward Overhang: Flush, Factory-Look Bars

The flush design keeps the crossbars tight to the roofline, giving your setup a clean, from-the-factory look. The bars don’t extend past the feet, so everything fits neatly and looks intentional. Whether you’re loading up for a trip or just driving around town, the Thule WingBar Edge blends in and keeps things low-profile.

Cut Down on Whistling: Aerodynamic Crossbars with Noise Reducing Strips

The aerodynamic WingBar shape helps smooth airflow over your roof to reduce wind noise and drag. Split rubber strips run along the top channel, closing around your accessory mounts to block out the whistling and vibration that can happen at highway speeds. It’s a smarter design that keeps your ride quieter and more comfortable.

Take What You Want on Every Trip: Works with Channel-Mount and Clamp-On Accessories

These aero-style crossbars work with both channel-mount and clamp-on accessories, so you don’t have to limit how you use your rack. Add kayak carriers, bike mounts, ski holders, or cargo boxes—the setup adapts easily to whatever adventure you’re planning next. The split channel strips make it simple to slide gear into place without trimming or extra hassle.

Built to Handle Real Loads: Strong Aluminum Construction

Each bar is made from sturdy aluminum and rated for a 165 lb weight capacity (always observe your vehicle’s maximum roof load). The system includes two WingBar Edge crossbars, four Edge Fixpoint feet, and a custom fit kit for secure installation to fixed mounting points. The silver finish adds a refined touch while standing up to years of use.

Lock It Down When You Park: One-Key System Compatibility

For quick security, the rack is compatible with Thule One-Key System locks (sold separately). They deter theft of both the rack and any channel-mounted gear when you’re away from your vehicle. It’s an easy way to keep your setup protected whether you’re stopping overnight or parking at a trailhead.

One year in and it’s been great. Looks awesome, very functional, but I would recommend getting the windscreen as well. I didn’t want one, but if you have a sunroof and plan on using it, you’ll need the screen to avoid the noise. I haven’t maxed out the weight, but have put bikes, kayaks, and a roof box on with no issues. Would recommend 100%.

Install is easy enough, but the fit kit & fix points sit so damn high. The whole set-up looks extremely stupid on a sleek SUV.

Niiiiiice! Is what we say when we see the car now. The roof rack is well built. Instructions were easy- the letter specification to tighten the rack were a bit much. We had to adjust based on how things looked and jived with the car. Some soft cushion edging would not flush over the roof indentation edge, so we had to re-loosen and tighten the rack few times until all settled well. Bottom line, we wanted a solid rack that did not have overhang, did what it is suppose to, was low profile, and make the car look hot- check!!!! We are very happy! Best part about the entire experience however is etrailer. I swear, one might never need customer service or any help with their purchase, until they do. And what a customer service it is. Wow. It’s worth returning to etrailer for more business, purely because you want this business to do well and to remain in business and to show them how much we appreciate their excellent customer service.

Excellent service. I called etrailer and they were able to match the key for my old Thule box to the new key cylinders for this rack. They gave no guarantees, but they somehow made it happen quickly!

This "fit kit" from THULE does not impress me much. It does not sit flush with the roof rails of my 2021 Toyota highlander, doesn't really line up with the openings on the flush mount rails, and only attaches to the vehicle via one bolt at each of the 4 mounting locations. In that sense it's inferior to even the OEM toyota roof rack mount.
by:
Initially I was worried that I good not get a good Roof Rack configuration to match my 2022 Kia Telluride. When I asked etrailer for some assistance on the configuration, Jon was quick to reply with an excellent solution. He definitely knew the products. Unfortunately, my initial shipment was damaged but Gwen and team quickly got me replacements in the mail. I have received and installed all components and couldn't be more satisfied.
by:
One year in, this fit kit and the whole system have worked very well on my Kia EV6.

I miss the simplicity, in terms of cost as well as installation and removal, of the old Thule rectangular-bar racks, but this system looks better, is quiet, won't sag, and seems more robust.
