Yakima JetStream

The quiet and aerodynamic Yakima JetStream crossbars let you build a custom roof rack for your vehicle. The crossbars require 4 Yakima BaseLine, RidgeLine, SkyLine, or TimberLine towers and a custom fit kit (sold separately) to mount the rack to your roof. Each bar extends past the towers to maximize space for mounting carriers and accessories. SmartFill strips push down for easy loading in the T-slots so there's no need to trim them. The bars are constructed of aluminum so they're durable and won't rust.

Aerodynamic JetFlow Design

JetStream Aerodynamic Design

The JetStream's asymmetrical JetFlow shape and built-in WindRidge helps to control air flow over and under the bar. This dramatically reduces wind noise and vibration - even at highway speeds - and eliminates the need to add a fairing to your roof rack. The aero-style bar also reduces drag to help maintain fuel efficiency.

Strong, Durable Construction

JetStream JetTruss Extrusion

The JetStream crossbars are made of anodized aluminum with internal JetTruss extrusions. These extrusions strengthen the bars without significantly increasing their weight. Additionally, because the bars are aluminum and have a black powder coat finish, they won't rust or corrode so you can leave them on your roof year-round.

Hassle-Free Installation

JetStream Bottom Channel

Each JetStream crossbar has a bottom channel that allows you to mount it to any of the Yakima StreamLine towers - BaseLine, RidgeLine, SkyLine, or TimberLine. The rubber strip in the channel can be cut down to the exact size needed for installation and then re-installed in the channel. This helps keep dirt out of the bar and reduces wind noise.

JetStream Etched Measurements

Etched measurements along the bottom channel help you center the bar on your roof. Simply use the ruler on each end of the bar to ensure the towers are spaced properly in the channel.

JetStream Installation Bracket

Once you have the correct measurements, install the brackets in the bottom channel, set the bar on top of your towers, and tighten it in place with the torque tool (included with your towers).

Channel-Mounted and Clamp-On Accessories

JetStream SmartFill Rubber Strips

JetStream crossbars have built-in top channels that allow you to carry channel-mounted accessories on your roof. Simply push down on the rubber SmartFill strips and slide your gear into the channel - no need to remove or cut the strip.

JetStream Clamp-On Accessories

You can also attach most universal, clamp-on accessories and carriers to the bars.

Maximum Cargo Carrying Capacity

Full Length JetStream Crossbars

The JetStream is a full-length crossbar that extends past your Yakima towers. The increased length gives you more space to mount accessories and carriers to your roof rack.

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!!


The JetStream crossbars are awesome. Unfortunately the box that these came ' in was damaged, and when I opened it both crossbars had scratches. It is only cosmetic, but when you pay top dollars for a good product you expect that it will be well packaged so is not damaged when shipped. If it wasn’t for the damaged packaging and scratches I would give it 5 starts.


These bars are the cats meow! Love the look of an aircraft wing. Easily supported our 2 kayaks.


First trip with the new rail system and it looks like it worked out just fine. Thanks to both of you and Kimberly for all of your help and follow up I do appreciate it.

Subaru Outback Wagon

These load bars are GREAT! I specifically bought these because they can comfortably handle any kind of sheet goods, including baltic birch plywood which comes in 5'x5' panels; it's much easier to securely strap down plywood when it's not hanging off the ends of the load bars.

These extruded aluminum bars are light enough that they're not a hassle to install and remove - I only put them on briefly when I need them, so I've had them on and off a dozen or so times and it's easily a one-person task.

They are of course very long, so I can't deny that there's more opportunity to bang your head on them when getting in/out of the car, but they are no wider than the footprint of the car (Subaru Outback) itself so they're not at risk of hitting a pedestrian or anything.


2011 Toyota Highlander

Really like these aero bars. Previous rack had round bars and these are noticeably quieter. Install was easy. Bars look and feel like quality equipment.


Great service. Hally took good care of me. Letting me know when the order was processed, shipped, and delivered. When I had an issue, taken care of immediately. The product itself is as expected and with great Yakima quality.


Great price and lightning fast delivery. This is my 3rd purchase from and their service and quality are second to none. Highly recommend.

2020 Ford F-250 Super Duty

Great follow up service when buying from this site.




2019 Ford F-350 Super Duty




2022 Ford F-250 Super Duty


Yakima Baseline with Yakima CBX 18 Cargo Box fitted on my 2012 Toyota Corolla S Sedan 2012.

Instructions were clear and roof rack was easily installed.


Not a bad setup. I dont believe you need the 60" bars i received as they hang over the edge of your Hyundai. You need to watch your head getting in and out of your vehicle. The Jetstream crossbars are very loud at speeds over 65 mph. Im probably used to it by now, but it is definitely noticeable. Much louder than an older Rhino Rack of similar dimensions i had. Install was simple and took about 30 minutes, just take your time and measure correctly like all roof racks.


For a 2015 Mazda 3, 4 door sedan.
used the 50" jetstream bars with the skyline towers and the #22 Landing Pads.
Went together easy, great quality, very solid feeling! And, easy to remove and install when needed.


I chose Yakima because I had one in the past and they were always reliable. Thule was my next choice but didn’t like the look of 53’ crossbars on my car. I really appreciated the easy to follow instruction that made installation a breeze. The kit came complete with everything I needed to install right out of the box. I purchased the 2 Hightower bike racks to go with the roof rack system and plan to safely secure both bikes for our trips. It was a bit heavier than I anticipated (combined with the bike carriers) which will hurt my MPG but having easy access to disassemble the bike carriers when not in use made it a no brained. Additionally, I love the look of the system on my car.


The 50” jetstream cross bars were perfect for my 2019 Ford Ranger with my ARE cap. They are paired with the Yakima Skyline towers and appropriate landing pads (protip: call etrailer when you order to ensure you have the correct setup;)

These cross bars are SILENT on my cap. Zero wind noise. My daughter and I installed them on a Friday (I do recommend watching etrailer’s installation video in addition to the paper instructions) and left for a 700 mile weekend road trip the next day to pick up a kayak, paddle with friends downstate then drop her off at summer camp.

Even with empty Yakima Jaylows on top, no wind noise. Even with a boat in the Jaylows, no wind noise.

These are the sweetest rack’s I’ve had. With the Skyline towers and landing pads, they are also easy to take off and put on. Click click done.

They look good, too;)

etrailer customer service for the win, too. When I originally ordered, I did not order all the items I needed for installation. When I realized this, I called and they got me squared away.


I have a 2015 Jeep Grand Cherokee SRT which has the non-functional roof side bars. helped me figure this out and gave me several options that would work. As I already have Yakima bike racks - I wanted to stick with the brand. The price on was the same as Yakima but had free shipping and no tax - awesome. Product arrived quickly!

I went with the Yakima 60" Jetstream cross bars, baseline towers, and the appropriate pads and clips.

The Yakima product came with thorough and easy to understand instructions. I was able to get the track installed and working in about an hour - and that was taking it slow and double checking everything. I was very pleased with the fit and finish.

After a test run, there was no wind noise or issue with the rack. Looking forward to taking a road trip next month with it!


The yakima jetstream crossbar looks beautiful. Quality is great. Took my vehicle for a test drive, and i didnt hear anything loose or broken from the bars. Very satisfied with the product and the instructions were great. It was my first time installing a roof rack too.

  • Recommended Yakima Fat Cat Adapter for Jetstream Crossbars
    The universal MightyMount part # Y03590 is a fit for the older style of Yakima FatCat 6 and can fit crossbar sizes up to 4 inches wide and 1-1/2 inches tall; the Yakima Jetstream bars like the # Y00427 are 3-1/8" wide and 1" tall, so this adapter will work on them.

  • Replacement Base for Yakima Skyline Towers on Camper Shell

If that isn't the case, then the Yakima JetStream Truck Bed Rack for Tonneau Covers - Aluminum - 70" Long # Y00427-482104 will work to give you the complete kit for your rails.

  • Can Yakima Jetstream Crossbars Be Installed On a 2018 BMW X5 M?
    Since the Baseline Towers # Y28TR are only designed to be used on vehicles with a naked roof you are going to have to switch to the RidgeLine Towers # Y00145 to fit the flush rails on your 2018 BMW X5M. You will also need to get the RidgeClip kit #10 from Yakima as we no longer carry these clips. I do see your roof will allow for either the 60" # Y00426 or 70" # Y00427 Jetstream crossbars.

    In order for the 33" Flints to work on your rack with the Yakima BigCatch Kayak Carrier # Y04091, you will need a minimum of 66" on your crossbars.
