Can 3 Crossbars Be Installed on 2019 Lexus LX 570 Flush Rails

Question:

How does distance between bars affect wind noise? If you install them at a distance greater than 70cms is the wind noise going to be much louder? If you wanted to install a 3rd cross bar, wing edge black is it possible to order it separately with all the required components? Thank you.

It won't help the wind noise if you install more than 2 crossbars on your 2019 Lexus LX 570, so the parts you're looking for are the following:

- WingBar Edge Crossbars # TH56FE
- Edge Flush Rail Feet # TH89SC
- Fit Kit # TH186044
- Lock Kit # TH450400 (optional)

The only time there is much of a benefit in placing more crossbars on your vehicle is if it was something like a Suburban with a larger roof area so you can use larger accessories.

Since your concern is with wind noise I recommend installing a fairing as well. You should be able to fit the 44" Long AirScreen XT # TH82WV but I recommend measuring the distance between your flush rails so you know if the 44" will fit or if you need the smaller 38" part # TH72WV instead. This helps to get the air up and above your crossbars to help with that air flow and lower whatever noise might be produced from the aero-style bars.
