Features to know about

Stay Stable and Confident on Every Haul: Heavy-Duty Steel CoreBars

When you’re loading up kayaks, canoes, or a cargo box, you want bars that won’t flex or bow under pressure. These CoreBars combine the strength of steel with an aerodynamic shape that keeps everything steady and quiet. The black vinyl coating protects them from corrosion, so they stay tough trip after trip. Each bar measures 60" long x 2-3/4" wide x 1" tall, giving you solid space and a 220-lb weight capacity for all kinds of gear.

Cut Down on Road Noise: Aero-Style Crossbars

Long drives are better without wind roar overhead. The aerodynamic design of these bars helps streamline airflow over your roof so you can enjoy a quieter ride. Whether you’re cruising to the lake or heading cross-country with a cargo box on top, the smooth shape helps minimize drag and noise for a more relaxed drive.

Get More Out of Every Trip: Full-Length Bars for Clamp-On Accessories

If you like switching between hauling kayaks, bikes, or a roof box, these full-length bars make it easy. The design works with most clamp-on accessories, so you can set up your favorite carriers without extra hardware. It’s a flexible setup that lets you load what you need for any kind of weekend or vacation adventure.

Keep It Secure and Simple: Custom Fit with Optional Locks

The system includes 2 CoreBars, 4 BaseLine towers, and a custom fit kit designed for your vehicle’s naked roof. Everything installs securely for a stable setup that won’t shift once tightened down. And if you want to add theft protection, Yakima Same Key System (SKS) lock cores are sold separately so you can lock the rack and keep your gear secure wherever you stop.

I was able to use these clips to mount a roof rack and roof box on my Audi that had a naked roof, and they did the job! I took it on a 1,200 mile road trip and after I returned there wasn’t any damage to the paint, and even though there are rubber inserts on the inside of the clip to prevent scratches I was still a bit surprised.

If you don’t have roof rails on your car, these definitely help!

Ford Flex
We purchased the Yakima Skyline Towers roof rack with the Jet Stream crossbars. Took about 2 hours to install on the naked roof of our Flex. I drilled through the roof strip for the mounting bolts and they fit tighter than the factory rails. Very happy with our choice.
by:
Perfect. Perfect. Easy to install and high quality. Confident in this product. Excellent instructions. Used with towers of course! Towers and crossbars have demonstrated to be strong and durable with several trips with kayaks.

Thanks, Eric! Glad the crossbars have been working well for you :)

2011 Honda Element
Was skeptical at first because I needed the posts as well for my 2011 Honda Element. The Honda crossbars were not adequately weight rated and is why I opted for Yakima. Couldn't be happier with my choice as this assembly has served me well throughout the year.
by:
I ordered the wrong set up for my car, but the excellent customer service specialist set me up and expedited my roof rack that fit perfectly. I highly recommend calling and speaking with the knowledgeable staff about your needs. I'm super happy with the experience overall!

Really easy to install & work as specified. So happy with the customer support/service at etrailer.

2019 Toyota Highlander
I have not bought car roof racks for decades--back when there were those very useful rain gutters. So I was shocked with the high prices. But what you get today is much more carefully engineered with a complicated construction. This Yakima version even comes with a manual 3.5 mm hex driver which turns out to be a torque wrench too. You use it 16 times, torquing to its limit, in installing the two cross rails on the four towers. Years ago you installed the towers where you wanted them on the rain gutters and adjusted the cross rails by sight. No more. You must go on line to Yakima. You must get the precisely engineered dimensions for your exact vehicle. You even adjust the towers for the roof slope and any toe-in of the roof line. Pay attention to the precise instructions. The result is very solid. I wish that I had more space between the cross rails. There is room for another 6 or 8 inches given where the door openings on my 2019 Toyota Highlander are spaced. But then the rear base clips would be different and that logistics would add yet more to the price. I am confident that I can secure a 4 X 8 sheet of plywood on the cross rails. And I will find my vehicle in the mall parking lot easier with those good looking rails. While I am happy with the end product, I wish the vendors had given more explanation of the fixed dimensions of today's installations. That would have helped make my on-line shopping less frustrating. Part of the problem is that Yakima and Thule do not provide cross rails for my LE Highlander's existing tower bases. And I could not get 60 inch cross rails on any of the versions that fit my LE's bases.
by:
The roof rack has been awesome! It has been really handy to be able to attach our bike rack attachment, kayak bars or traveling cargo carrier. My only complaint is that the end caps fell off somewhere along one of our many adventures and looks a bit disheveled. Other than the appearance it has been very versatile and we love it!
by:
Great UX for finding the options matching my car, and the baseline towers work great. Simple straightforward site, will plan to use them again when needed.

For those also buying crossbars for cars without roof rails, recommend taking a silver sharpie and marking the placement of the crossbars on the weather seal at the top of the door openings. Makes putting them back on way less of a hassle if you don’t want them on 24/7.
by:
I want to thank the staff at eTrailer for their outstanding support. After my roof rack order got off to a shaky start the customer service staff stepped in and made it right; 100% RIGHT. I cannot thank them, and eTrailer, enough. Regarding the roof rack itself, I have now installed it and can vouch that the installation was a breeze. All parts fit and the instructions were correct. For the record, this is not my first purchase from eTrailer (I've bought hitch items from them before) and it won't be my last. They have ALWAYS given great service, their web site works, their products and descriptions are good, etc., etc. Thank you!
by:
I did a lot of research before purchasing my roof rack. I came across this website and liked the prices, and after much thought, decided to get the Yakima CoreBar crossbars. I received my roof rack within a couple days of ordering! It's extremely sturdy and doesn't make hardly any wind noise. I love it and it looks great on my car, couldn't be happier with my purchase!!
by:
The instructions were different for another set of bars. Was a pain to get right...all the measurements on Yakima were off...I figured it out on my own...should have got Thule or nicer bars ..end caps were not good either...flawed fit... otherwise will do just not happy with the product perse or instructions...delivery good...will see how they do.
by:
Had all parts in stock. This is the number 1 reason purchased from Etrailer.com. I was given tracking info the entire way to destination. Order shipped same day. Definitely a 5 star company. Thanks Etrailer.com.

2017 Kia Sedona
This Yakima rack system for my 2017 Kia Sedona works great and are rock solid. I have two Kayaks I take to the lake, river, and beach house for vacations. Dena was extremely helpful and kept me up to date on everything. It’s very seldom to find a company with reps that actually care about the customer!!!! Please keep this going! The shipping was fast and easy and I had them installed within an hour in this Georgia heat! The only thing missing was the etrailer stickers......... ;p I would definitely recommend this product from etrailer for any of you rack needs!!!
by:
Love my Yakima roof rack!! It exceeds my expectations.great product. Also thank etrailer for the tec support! great staff always there to help thanks again!!
by:
The 60" CoreBar Crossbars will be much more useful to us than the original 50" bars placed on our shell at the factory. The only issue I had was that there were no instructions with the bars. It took a little while for me to figure out how the old bars came off and how to put the new ones on but I'll consider that a learning experience.

Also, removal just as fast.
Thanks again.

Had two different vehicles to get ready for two different trips and Joshua diligently tracked dow the correct Yakima accessories and backorder challenges. No other provider came close to this level of service. Excellent work! Both trips made better!
by:
These crossbars have held-up well across for a year now on multiple road trips across some major climate swings - so far, so good!

Chevrolet Silverado
Excellent solution for my 2023 Chevy Silverado. In the past, I have had rails installed on the roof of my pickup trucks, but I find the BaseLine towers to be a better solution, since they don't permanently change the truck. Plus, they are much more solid than SkyLine system on the rails.
by:
I have truly enjoyed this system. It allows our family of five plus our dog to stretch out in the car while our gear is secured on the roof. It takes a bit to mount it but I want it secure and it does fine with a roof box at interstate speeds. I absolutely recommend this system.
by:
Product was packaged well, arrived in perfect condition.
Instructions easy to follow. Installation took less than (1) hour. I did it alone & I’m 76 yrs. old.
Is very sturdy. Looks good on my 5 door Subaru.
The feature that impressed me the most in dealing with your company was how I was able to track my package inside your facility with the name of the employee handling the item before it even shipped. Very organized. Would definitely recommend you to others & purchase from you again.

So far so good. Purchased these towers to use on a 2022 GMC Canyon with HD bars that I already had, primarily to carry my canoe. Yakima's fitting instructions worked perfectly and the whole system seems really solid.
