Hey Michael. There is no custom fit set of towing mirrors for your 2020 Lexus GX 460, however I do have a universal option. They are the K-Source Universal Towing Mirrors item # KS3891-2. I really like these since they've got a large mirror face of 7-3/4" tall x 5-1/8". These K-Source mirrors have ratcheting straps to secure them to your Lexus. They help reduce vibrations and and ensure a tight grip.

Seeing how these are universal, I do not know if these will block your blind spot monitors.

Where on the mirrors is the sensor located at?

On the 2020 Lexus GX460, the Blind Spot Monitor (BSM) system does not use sensors embedded in the side mirrors themselves. Instead, it uses radar sensors located behind the rear bumper, typically on the left and right corners. so mirrors are not a problem, but the trailer might be :( So I will order the mirrors. With that said I also want to add some helper air bags / springs / bump stops. what do you recommend.

@MichaelD Sounds good, yeah I'm not sure either. May want to check your owner's manual for that information. Other vehicle's have a tow setting so you may want to see if your Lexus addresses the sensors in a similar way. The best suspension enhancement for your Lexus is going to be the SumoSprings Solo Custom Helper Springs item # SS68DR. These springs have progressive load control which means they only engage when you put weight on the rear end. If you're not towing your trailer you won't even notice them. They will do a great job of stopping your rear end from sagging and combating sway.
