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.

  • 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.

    The only way to carry a kayak and/or canoe on the 2020 Ram 1500 while towing is to install a roof rack on the truck and use a carrier.

    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.
