Features to know about

Stay Stable on Every Haul: Integrated Crossbar and Tower System

This setup makes carrying gear secure and simple. The integrated crossbar and tower system connects directly to raised side rails, keeping everything locked in place when you’re hauling kayaks, canoes, cargo boxes, or camping gear. With a 165-lb weight capacity, it handles weekend trips and long road adventures without flex or wobble.

Keep It Clean and Low-Profile: Flush, Factory-Look Design

If you prefer a rack that blends in instead of sticking out, the flush design does exactly that. The bars don’t hang past the towers, giving the setup a streamlined, factory look. The matte finish towers add to that clean style while resisting weather and corrosion so the rack keeps its sleek appearance season after season.

Cut Down on Drag and Whistle: Aerodynamic JetStream Crossbars

The JetStream crossbars are built from lightweight aluminum to resist corrosion and reduce wind noise. Their aerodynamic shape helps air flow smoothly over the roof instead of whistling through gaps. The push-down rubber strips in the top channels seal right back up after mounting accessories, keeping the setup quiet mile after mile.

Pack Up for Any Adventure: Works with Channel-Mount and Clamp-On Accessories

Whether it’s kayaking in summer or loading a cargo box for a long road trip, these bars are ready to go. The top channels fit channel-mount accessories while still working with clamp-on mounts like carriers and baskets. That means you can mix and match gear—kayak cradles, fishing rod holders, cargo boxes—without needing separate racks.

Lock It Down When You Leave It: Compatible with Yakima SKS Lock Cores

You can add Yakima Same Key System (SKS) lock cores (sold separately) for theft deterrence. With the locks installed, the rack stays secure when parked at a trailhead or campsite, giving you peace of mind while you’re off enjoying the adventure.
