This setup connects directly to flush rails for a solid, custom fit. The design gives a sleek, factory-style look while keeping the crossbars secure and evenly spaced. It’s a fixed position system that feels sturdy and purposeful once installed—no sliding or shifting needed, just a confident mount that’s made to stay put.
Driving with roof bars doesn’t mean you have to deal with constant wind noise. The aerodynamic WingBar Evo design smooths airflow over the top of your vehicle. The split rubber strips inside the top channels reduce vibration and noise while sealing out wind. You still get the performance of a full rack system without having to turn up the radio to drown out whistling.
These 50" Aero-style aluminum crossbars work with both channel-mount and clamp-on accessories. That means you can easily attach bike racks, kayak carriers, ski mounts, or a rooftop cargo box without worrying about compatibility. The top channels make sliding your mounts into place simple, and the split strips close around them—no cutting required.
The whole system is built around durability and function. The aluminum bars handle loads up to 165 lbs (always follow your vehicle’s limits) and resist rust or corrosion from weather exposure. Whether it’s holding boats, tents, or boxes full of camping gear, you can trust it to stay solid mile after mile.
You can upgrade this rack with Thule One-Key System locks (sold separately). They secure both the base rack and any channel-mounted accessories using a single key. It’s an easy way to keep your gear protected when you park at trailheads or overnight stops on road trips.

This is the first top of the line roof rack system I have purchased. I never expected to have issues but this thing is so universal, with gaps everywhere, that I can’t get it to stop whistling. I wish I could return and get my money back. I really expected something better from such an expensive system.
The online tutorial was excellent and I was able to install the roof rack myself. The only disappointment is my board loader doesn’t work with the flush mount system.
Love Thule products!
Alex and etrailer are great to work with. My original order was misplaced by the shipping company. I needed the cross bars for a trip and Alex overnighted an extra pair so that I had what I needed. Alex came through when I needed his help. Great customer service.
Thule products are not the cheapest but they are just so well engineered it brings a smile to your face every time you assemble them. I have 7 year old aero blade bars and bought these foot packs (and fit kit) for a new car. Taking off the old feet off the bars was flawless - every part, whether plastic, rubber or metal is still perfect after 7 years of use and shed storage.
Etrailer were fabulous as usual - initial phone consultation to confirm feet will fit old bars and then quick online ordering etc.
The rubber guides in the Evo bars came out within months of beginning to use it. Once the seal popped out the bars whistle annoyingly.
etrailer was the only place that was able to provide a solution for me! I have a 2022 GLC Benz with panoramic roof. I spent many $$ for Benz’s own cross bars. They looked great…integrated with the roof seamlessly. But I couldn’t open the panoramic roof! MAJOR FAIL!!
etrailer customized a set of Thule cross bars that not only work with my panoramic roof but are quieter and look even better than the Benz product. MAJOR AWESOME to etrailer. Now listing my Benz cross bars on Craigs.
I purchase these along w the Thule Evo Fixpoint feet & Thule mounting points. Took less than an hour to put together & it was pretty simple. I don’t notice any whistling noises at all so that’s great. Looks super awesome! If you’re thinking of getting a roof rack definitely go with the Thule, looks low profile and sleek.
Thule makes great products
And etrailer makes it too easy to get when needed.
etrailer.com was excellent to do business with. Their website is informative, complete and easy to navigate. Phone service to help confirm availability of my product and their general knowledge of their products was impressive. Product arrived on time and in good shape. Their order tracking system is also very good. I’m very pleased with the Thule Wingbar Evo 135 racks For my BMW X5 with flush roof rails. They are super sturdy, solidly mounted and look good on the vehicle. Mine will be mainly used for surfboards and SUP’s. The assembly and installation was a breeze. The included written instructions would have been sufficient for a seamless installation but I also watched one of many YouTube videos that demonstrated very clearly every step of assembly and installation for this specific set of racks.
Love the racks!! I highly recommend etrailer.com for your roof rack needs.
I ordered the Thule WingBar Evo Crossbars - Aluminum - Silver - 50" with the Evo Flush Rail Feet for Thule Crossbars - Flush Side Rails and the Fit Kit for Thule Evo Flush Rail and Edge Flush Rail Roof Rack Feet for my 2020 Mazda CX9. I appreciated the product selector to make sure I was getting all the correct parts. I was happy with the products, but I did run into an issue where 1 of the rail feet had a defective bolt which required a replacement. I was very satisfied with etrailer's customer support, and how well they worked with me to get the part replaced quickly. I'm giving this a 4 start only because of the hassle of receiving a defective one initially
Very pleased with order. Shipped fast, not damaged, all parts accounted for. Easy install, very sturdy, and attractive design. Slight wind noise but that was expected compared to not having a roof rack.
Easy to assemble and install. Love the way etrailer packages everything you need and they all are correct for the vehicle you are mounting them on. Once installed they appear very strong. Installed on a 2023 Chevy Tahoe and did not interfere with the sunroof.
I’ve had it on my 2021 Kia Telluride now for a few months and it works great. When I was mounting the forward bar, I opened the sun roof to make sure I was comfortable with the roof window and bar clearance.
QUALITY Crossbars! Aerodynamic, tested at 70mph on the highway with little to no noise disturbance! SOLID bars if installed correctly. Although there were instructions provided, they were a bit vague. Hop on YouTube, and you will find plenty to reference from! Most of it is self explanatory, but it’s always good having tips and tricks helping you through your particular install! A++
Rock Solid and good looking. Expensive but worth it!
Work great. The rubber pieces will start to pop up at times. I will hear the bars whistling so I just reset them and good to go. Overall the bars are quiet. We use a Thule cargo box on top and it works great for traveling.
Thule Rack looks awesome on my Kia Telluride. Products took a while to get to me because they were on backorder but it's not etrailer, they were on backorder everywhere. I messed up one of the pieces of rubber while installing and etrailer sent me a new one at no charge. Definitely recommend etrailer.
This is my first Thule product but not my last. etrailer was great to deal with the videos on how to install the product were so helpful. Between etrailer's help and all the reviews that other people had purchased and posted made this a very pleasant purchase and install. I highly recommend etrailer and the complete Thule WingBar system including the keylocks that worked perfectly.
One of the rubber strips came off somehow. I just used these bars for the second time.
Website is easy to use & is better at putting together the correct package than Thule’s site.
etrailer had all the parts in stock for my 2020 Kia Telluride.
Payment process was simple.
Received periodic updates from staffer on my order & could actually reply if needed.
Installing the roof rack went well. Estimate start to finish was about 2 hours. Found it best to really examine each diagram in Thule’s step by step instructions to get it all right on the first try.
Hardness part of the installation was getting the crossbars installed at the proper distances. A tailor’s soft measuring tape & some masking were great aids.
Everything fit like a charm!
Thule has great quality and trailer is a great place to order from, highly recommend both!
It took me a VERY long time to figure out what I needed to mount my Hullivator on my 22 Subaru Outback Limited. I bought the wrong parts on round 1, and finally after 2 yrs of frustration, asked AI what I needed. I don't entirely trust AI, but it got me on the right track. I asked the 'chat' person on etrailer about the AI suggestion, and the gal who helped me, Autumn, said the feet part was correct, but to use these feet and the TH37CE fit kit. I ordered immediately. Today was the day. Of note, the fit kit has specific parts for the front and rear passenger and front and rear driver side. Pay attention to the photo directions. The parts are different for each side. On my Outback, they mount at 69cm apart on the Subaru rails (folded in) on the Thule Wingbar Evo 55" bars. The cladding and design of the Outback roof system leaves much to be desired, but this worked and I'm looking forward to FINALLY using my Hullivator.
