When you’re hauling heavy gear like kayaks, canoes, or a fully loaded cargo box, you want bars that stay solid and don’t flex. The Thule WingBar Evo crossbars are made of aluminum and rated for up to 165 lbs of weight capacity. That strength gives you confidence whether you’re driving to the lake or across the country.
Wind noise can make any drive tiring. These aero-style crossbars are shaped to cut through the air, and the top channels include split strips that help reduce wind noise and vibration while you’re driving. The result is a quieter ride that feels smoother on long highway trips.
These bars are ready for all kinds of adventures—load up a kayak in summer, skis in winter, or a cargo box for your next road trip. The top channels work with channel-mount accessories, while the bar design also fits clamp-on gear. That flexibility means you can use most bike, watersport, snow, and cargo carriers without needing new hardware every time.
With some racks, you have to trim rubber strips before installing your gear. Thule’s split strip design solves that problem. Just slide your accessory into the top channel—no cutting required—and the strip closes around it. It’s clean, easy, and keeps wind and water out around your mounts.
If you want added theft deterrence, the bars are compatible with Thule One-Key System locks (sold separately). You can secure both the rack and your channel-mount accessories with a single key for peace of mind when your vehicle’s parked overnight or at the trailhead.

Review of Entire set: After a year of using this, it still works very well. Easy to take on and off your car and make slight adjustments if needed. Only maintaining is really just cleaning it which is simple enough. No issues with lockingunlocking with the keys. It has definitely helped saved space for my tiny Honda Civic.

My purchase from etrailer.com was world class. And their service was superb. They are a 5-star organization. They are knowledgeable folks with experience in what they sell. They will quickly get you out of what would otherwise be a nasty, complex situation and make it look easy. You can trust this company. Put them to work for you. Note, I do not own stock in this company but wish I did.

I can see that you got the 52 inch Thule square bars. The square bars are known to whistle compared to the aerodynamic cross bars. I recommend the Thule AirScreen XT part # TH22WV to divert the wind up and over the cross bars to eliminate some of the wind noise.

Most of the time whistling occurs because the rubber strip is not covering the whole channel. You can find installation tips here in the attached expert answer. There will be some wind noise as with all brands of roof racks. Wind fairings greatly reduce that by adding an aero-dynamic ramp allowing the wind to flow over the roof rack. The Thule Wingbar Evo crossbars that you purchased are actually designed to act as a fairing so one would not be needed. You could still get one if you wanted to try it out. This one would be the best match for you: item # Y05018.
