TimberLine Towers

The heavy-duty TimberLine towers allow you to mount 2 Yakima crossbars to your vehicle with raised, factory side rails. The towers install with rubber-coated stainless steel straps that wrap around your side rails. And the TimberLines' versatile BarBeds accommodate Yakima's full line of crossbars.

Versatile BarBed

Versatile TimberLine BarBed

The TimberLine's BarBed is designed to work with Yakima's entire line of crossbars.

CoreBar CrossbarJetStream Crossbar

The BarBed is curved to accommodate the elliptical shape of the CoreBar and JetStream crossbar. The CoreBar includes brackets that slide over the bar and secure to the towers with bolts. The JetStream attaches directly to the tower with bolts.

RoundBar CrossbarRoundBar Adapter

The towers also work with Yakima RoundBars with adapters (Y03536 - sold separately). The adapters slide over the bars and secure to the towers with bolts.

Secure Installation with Rubber-Coated Stainless Steel Straps

TimberLine Removable Straps

The towers install easily with rubber-coated stainless steel straps. Simply remove the tower covers, wrap the straps around your raised side rails, and secure the straps to the towers. The straps provide maximum contact and security by wrapping completely around your side rails.

TimberLine Straps Tighten with a Single Bolt

Tighten the bolts inside the towers with the included torque tool to complete installation. This is the only tool you will need to secure the towers to your rails and your crossbars to the towers. The torque tool also helps prevent over- or under-tightening. The tool clicks 3 times once you've reached the correct amount of torque.

Same Key System Locks

4 Pack SKS Lock Cores

TimberLine towers are compatible with Yakima SKS lock cores (Y07204 - sold separately) that allow you to secure the roof rack to your roof. The SKS locks are all keyed alike so a single key opens all the locks. The locks can also be swapped out to make all of your Yakima products keyed alike.

  • Recommended Roof Rack for 2019 Ford Escape with Factory Raised Rails and Panoramic Sunroof
    For your 2019 Ford Escape with the factory raised side rails I highly recommend the Yakima JetStream Roof Rack that consists of # Y00426 for the two 60 inch JetStream Crossbars and # Y33TR for the TimberLine Towers that will attach to the side rails. This is an excellent, aerodynamic system that will result in an extremely quiet ride and it features a 165 pound weight capacity. The 60 inch bars represent the longest units available for your Ford Escape to allow for more usable space to...

  • Roof Rack Weight Capacity on 2019 Ford Escape with Moon Roof
    I checked your owners manual and the weight capacity of 100 lbs without moonroof or 45 lbs with moon roof are for the factory crossbars. Granted, aftermarket crossbars won't greatly increase the capacity, so carrying two kayaks on a moon roof Escape is not a great idea. If you don't have the factory roof rack, then I recommend the Yakima JetStream Crossbars - Aluminum - Black - 60" Long - Qty 2 # Y00426 and TimberLine Towers # Y33TR which are rated for 132 lbs. These ratings are based...

  • Recommended Roof Rack for 2019 Volkswagen Golf 5-Door with Raised Rails
    I do have a great roof rack option for the 2019 Volkswagen Golf 5-Door with raised side rails however the Whispbar Brand is no longer in production with Yakima. I recommend the Yakima JetStream Crossbars part # Y00425 with the TimberLine Towers part # Y33TR on the 2019 Volkswagen Golf. The JetStream bars are low profile aerodynamic bars much like the Whispbars. The biggest difference is the bar sits atop of the foot instead of through it which makes the rack more versatile when it comes...

  • Parts Needed to Install Yakima CoreBar Roof Rack on 2015 Toyota Sienna
    The 2015 Sienna is equipped with rails that run fore and aft along each side of the roof, so you'd need the # Y33TR TimberLine towers to connect the # Y00423 CoreBars to the rails. No separate fit kit would be necessary!

  • Compatibility of Thule Upride Bike Rack with Yakima JetStream Roof Rack Crossbars
    The dimensions of the T-slot are consistent between Thule, Yakima, Rhino Rack, Inno, Malone and most of the other major players. Your Thule accessories that are designed to mount in the slot or channel in the top of the crossbar will indeed be compatible with the Yakima 60 inch # Y00426 crossbars. Yakima confirms that the 60 inch crossbar along with the # Y33TR TimberLine towers will indeed work on your 2012 Toyota 4Runner Trail. I've linked you to our Roof Rack help articles.

  • Recommended Towers for my 2012 Subaru Outback to Attach my 60 Yakima JetStream Crossbars
    We can get you set up. All you'll need are the TimberLine Towers for Yakima Crossbars - Raised, Factory Side Rails part # Y33TR. These will clamp on to the side rails of your 2012 Subaru Outback and allow you to connect the Yakima JetStream Crossbars part # Y00426.

  • Weight Capacity of Yakima Roof Rack on 2019 Ford Expedition
    You are correct that the TimberLine Towers # Y33TR limit your weight capacity over the Yakima Crossbars # Y01157, but in this case it is actually your vehicle's roof load capacity that is the real limit. Based on my research, a 2019 Ford Expedition has a roof load capacity of 125 lbs if you have a moonroof and/or 20 inch wheels, otherwise it has a roof load capacity of 200 lbs. Check your vehicle owner's manual to make sure. Since the weight capacity of your vehicle is lower than the capacity...

  • Can 60 Inch Long Yakima Y00426 JetStream Crossbars Be Used on a 2017 Subaru Forester
    You can certainly use a 60 inch long crossbar such as the Yakima # Y00426 JetStream. In order to attach the crossbar to your current roof rails, you'll also need the # Y33TR Yakima TimberLine towers. If you click the provided link, you can see a similar rack (same roof rack with 50 inch crossbars) being installed on a 2017 Forester like yours.

  • Availability Of Roof Rack That Utilizes Factory Holes On 2011 Chevy Avalanche
    I confirmed that there are not any roof racks that will be able to utilize your factory drilled holes that the OEM roof rack attached to on your 2011 Chevy Avalanche. If you are able to keep the factory rails then you can install Yakima JetStream Crossbars - Aluminum - Silver - 60" # Y00426 along with TimberLine Towers # Y33TR. These bars have the standard T-slot channel on top which allows for channel-mounted accessories to be easily installed or removed. I attached a demonstration video...

  • Side Rails Compress with Yakima Timberline Towers on 2015 Ford Explorer
    It's normal for the raised side rails to compress slightly when installing the Yakima JetStream Crossbar System part # Y00426 and part # Y33TR on a 2015 Ford Explorer. That said, so long as you are using the included torque tool there will be no issues with deformity. The tool only tightens to 2.5 ft. lbs.

  • Parts Needed to Mount Yakima Space Cadet Cargo Box on Roof of 2008 Honda Odyssey
    In order to mount your Yakima Space Cadet Cargo Box to the roof of your 2008 Honda Odyssey you will indeed need to add crossbars. For your Odyssey that features the factory raised side rails I recommend the Yakima CoreBar System. This roof rack consists of # Y00421 for the two 50 inch CoreBar Crossbars and # Y33TR for the TimberLIne Towers that will attach to the side rails. I have attached a short video demonstration on this roof rack that you can check out. As long as you still have...

  • Minimum Crossbar Length for Yakima Roof Rack on 2019 Honda Ridgeline
    According to Yakima, the shortest crossbars that will work on your Ridgeline is their 'medium' crossbar which is the 60 inch long # Y00426. If you go any shorter than that, the bar won't be long enough to properly connect to the roof rack feet. To provide a rack, if you have the bare roof you'd need the following: 60 Inch Crossbars, part # Y00426 BaseLine Towers, part # Y28TR Vehicle Specific BaseClips, part # Y06152 If your Ridgeline has the side rails on the roof, you'd use the same...

  • Crossbar Recommendation for 2015.5 Volvo XC70 w/ Factory Installed Rails
    Since Yakima was unable to confirm a fit at this time for the 2015.5, I made a call our local Volvo dealer to obtain some information. My contact there states that the factory installed rails on the 2015.5 Volvo XC70 are the same as those on the 2015 model. With that being said, the Yakima Roof Rack, consisting of parts # Y00408, # Y03536, and # Y33TR fit your Volvo. As always, you will want to check your owner's manual to determine the roof's carrying capacity before loading any cargo...

  • Which Yakima Roof Rack Fits 2014 Mazda CX-5 with Raised Side Rails
    For your 2014 Mazda CX-5 with Raised Side Rails we offer several Yakima roof rack options you can see on the linked page. I recommend the Core Bar rack system made of parts # Y00421 and # Y33TR. This costs the same as a basic round bar rack but it will create less wind noise thanks to the bars' more aerodynamic shape. I've linked you to some FAQ articles about roof racks and their available accessories.

  • Yakima Core Bar Roof Rack for 2015 Ford Flex
    The Yakima Core Bar Roof Rack kit for the 2015 Ford Flex with roof side rails consists of the 60 inch long core bar itself, part # Y00422 as well as the TimberLine Towers, part # Y33TR. This rack is indeed a fit for your 2015 Ford Flex, and includes the installation tool needed to connect the Towers to the existing roof rails. Lock cores are sold separately as part # Y07204.

  • Will the Yakima Skybox 21 Cargo Box Fit a 2012 Mercedes GLK 350
    Yes, the Yakima SkyBox 21 cargo box # Y07337 will fit your 2012 Mercedes GLK 350 with factory roof rack and crossbars. If your GLK 350 just has the factory side rails that run front to back and no crossbars that run side to side then you would need to add crossbars first and then you can mount the box. To keep everything in the Yakima family I recommend TimberLine Towers, # Y33TR, with Yakima JetStream bars # Y00425.

  • What Length Yakima Jetstream Cross Bars Fit 2010 Subaru Outback Wagon
    For your 2010 Subaru Outback Wagon with factory installed rails that run front to back the folks at Yakima recommend their 50-inch Jetstream Crossbars # Y00425. These bars install using the TimberLine Towers # Y33TR. Generally roof rack bars should not extend out much past the roofline as this could pose a bump hazard. Bars should never extend out further from the vehicle than the side mirrors do. For reference I have linked an installation video.

  • Recommended Roof Rack for 2014 Toyota 4Runner
    I suggest the Yakima JetStream crossbars for your 2014 Toyota 4Runner. These are aerodynamic bars that reduce wind noise. They allow both clamp-on and channel-mounted accessories to easily be installed. For the complete roof rack you'll need: 50 inch JetStream Crossbars # Y00425 TimerLine Towers # Y33TR The roof rack can also be locked using Yakima's SKS Lock Cores # Y07204. These allow you to have one key work with all of your Yakima products.

  • Roof Rack With 48 Inch Crossbars Recommendation For 2013 Subaru Outback Wagon
    If your 2013 Subaru Outback Wagon has the factory raised side rails, I recommend the Yakima Roof Rack With The TimberLine Towers. For this system you will need to order part # Y03536, part # Y33TR, and part # Y00408. This system includes 48 inch round crossbars. The Yakima JetStream system referenced above is one of the best on the market as far as quality and ease of use goes!

  • Recommended Yakima Crossbars for 2016 Maza CX-5
    Both the Yakima JetStream Crossbars # Y00425 and CoreBar Crossbars # Y00421 are great aero-style bars that are confirmed to work with TimberLine Towers # Y33TR on your 2016 Mazda CX-5. These are two very similar crossbar designs, and partly because of this, I recommend going with the more economically priced CoreBars # Y00421. The aerodynamic design and teardrop shape on these bars will help to create a quiet roof rack system and reduce wind drag to maintain fuel efficiency. As you...
