Which roof rack cross bars are recommended for the Buick Enclave?

I would suggest being very careful with the sunroof clearance on the 2023 Enclave specifically. Proper tower selection is critical, tho the Yakima JetStream Aerodynamic Crossbars 60 inch work well for quiet highway speeds.

• use the Yakima SightLine Towers designed for flush rails
• verify the bar spread distance so your Thule box dont hit the rear hatch Honestly, just be sure to test the sunroof slowly the first time you install them to avoid any expensive scratches.

Just saw this and wanted to chime in because I went through the same headache with my Enclave. I've been really happy with the Thule WingBar Evo 135 setup. Honestly, the best part for me is the T-slot design where you dont even have to cut the rubber strip to slide your accessories in. It saves a ton of time during install. They're dead silent at highway speeds, which should keep your wife happy. I paired mine with the Thule Flush Rail Evo Foot Pack and the clearance for the sunroof is totally fine. It is a bit pricey tho, right at the edge of your budget. If you want to save a few bucks without sacrificing quality, I've also had great luck with the Rhino-Rack Vortex Aero Bar 1375mm. Use the Rhino-Rack SX100 Legs for those flush rails. These bars are incredibly sturdy and have a high dynamic load rating that handles a large cargo box with zero flex. The T-slots work perfectly with Thule or Yakima gear. Installation is pretty straightforward... just gotta make sure the legs are centered before you tighten everything down. Both of these options are way better than the OEM bars because they sit high enough that you wont be worried about the clamps rubbing your roof paint when you're loaded up for the Rockies.

^ This. Also, check out the Inno Aero Base Rack System with XS400 stays. It fits the Enclave flush rails well and stays under your $450 budget. T-slot works great with existing gear. Quick tip: check your owners manual for the roof load limit. Sometimes the car rails are the bottleneck, not the crossbars themselves. Its a very simple install too.

@Reply #1 - good point! about that sunroof clearance. I actually saw a guy at a trailhead who cracked his glass because his low-profile bars flexed just enough under a heavy cargo box to make contact. I'd be a bit cautious with the Thule setup mentioned earlier for that exact reason... they look sleek but the margin for error is tiny with a loaded XL box. I might suggest considering these instead:

• Malone AirFlow2 Aluminum Aero Cross Rail System 50 inch. These are surprisingly beefy and have a 165lb dynamic load rating. They sit about an inch higher than the Thule WingBars, which basically guarantees your sunroof wont hit anything even when the box is packed. T-slot works perfectly with standard accessories.
• Turtle Air1 Silver Roof Rack Cross Bars. These use a really high-grade 6063 T6 aluminum and the clamping force on flush rails is superior to most universal kits. They're rated for high speeds without the typical whistling you get from cheaper brands. I've used the Malones for a few seasons now and honestly, they feel more stable than the OEM Buick bars. Just make sure you check the torque on the mounting bolts after the first 50 miles of your trip. Those flush rails are slippery and if the bars shift even a few millimeters, it can mess with your wind resistance and start that whistling your wife hates. Better to be safe.
