Just found this thread! I went through this last year and man, it’s a total learning curve. Before you dive in, it's amazing how much the “vortex” effect matters—basically, air trips over the bar and creates that annoying howl.

Just sharing my experience with a few warnings:

1. Warning! Watch out for bars that sit too high. I tried some tall generic ones and the wind noise was deafening because of the air gap.
2. Seriously, make sure the feet are specifically molded for flush rails. I almost scratched my paint with a "universal" kit that shifted during a gust.
3. Don't forget the T-track rubber fillers! If you leave the top slot open on something like the Thule WingBar Edge for Jeep Cherokee, it whistles like a flute.

I eventually tested the Yakima JetStream Crossbars 50 inch Black and the stability was fantastic! Just be cautious with the torque settings. Good luck!

Watch out for those basic square bars or even the Mopar Jeep Cherokee Flush Rail Cross Bars if you're sensitive to noise. In my experience, the factory ones often lack the advanced aero-shaping needed to stay quiet above 60mph, and honestly, the whistling can get pretty annoying on a long haul to teh lake.

For your situation, I would suggest going with a high-end aerodynamic setup. Over the years, I've tried many, and the Thule WingBar Edge for Jeep Cherokee is the gold standard for a low-profile look that doesn't look like a bulky cage on top of your Jeep.

* **Aerodynamic shape:** Drastically reduces drag and wind noise compared to round or square bars.
* **Integrated design:** The Edge model blends into the flush rails perfectly.
* **T-Track compatibility:** Makes mounting things like the Thule Hull-a-Port XT Kayak Carrier a breeze.

You could also look at the Yakima JetStream Crossbars, but I think the Thule system fits the Cherokee profile a bit better. Good luck!

Same setup here, love it

Stumbled upon this discussion and had to chime in because I just went through this. I really wanted to love the Yakima JetStream Black 50in Aero Bar because they look so slick, but unfortunately, they were a total letdown on my Cherokee. Installing them myself was a massive headache... the instructions were vague and the fit felt loose no matter how much I cranked them down on my flush rails. The wind noise was also way worse than I thought it'd be, basically a constant whistle over 45mph. I switched them out for the Rhino-Rack Vortex ROC25 Flush Black 2 Bar Roof Rack recently. It is better, but honestly, it is still not the silent ride I was dreaming of. Had issues getting the rubber strips to stay put during the DIY setup too. It feels sturdier for the kayaks tho, which is the only reason I kept it. TL;DR: Yakima was noisy and a pain to install. Rhino-Rack is tougher for kayaks but still hums a bit on the highway. DIY takes way longer than the YouTube videos suggest.

I've spent way too much time doing market research on this before I finally bit the bullet on my current setup. From a technical perspective, you really have to weigh the manufacturing standards of the factory options against the high-end aftermarket brands. I’m pretty cautious when it comes to structural integrity, so I looked into the actual engineering behind how these things are tested for lateral force. Here are a few things I learned during my deep dive:
* Dynamic vs. Static Load: Most people only look at the weight limit, but for kayaks, you need a bar with a high dynamic rating to handle those sudden gusts.
* Foot Design: The way a system grips those flush rails is vital; I prefer systems that use a torque-limited tightening tool to ensure you aren't over-stressing the mounting points.
* T-Slot Standards: The premium brands usually follow universal standards, making it way easier to swap accessories later on. Basically, the cheaper factory stuff often uses a lighter-duty extrusion that can flex under pressure. For me, the extra investment in a Tier 1 system was worth it for the peace of mind alone (at least that's what worked for me). It really comes down to how much you trust the mounting hardware when you're doing 70 mph on the highway. Which way are you leaning?
