What Our Gearhead(R) Experts Are Saying:"The TimberLine FX sits flush to the roofline with no bar sticking out past the rails, so the whole setup looks like it came from the factory. The integrated tower clicks onto raised side rails without any extra hardware, and once it's on, it's solid."Why We Like ItThe JetStream crossbar profile is aerodynamic and T-slot compatible, so the same bar that looks clean on an empty roof accepts Yakima's full lineup of mounts and carriers without adapters. The SmartFill infill pops down to expose the slot and snaps back up around the mount base for a finished look between accessories.
