Question:

Im looking for some suspension airbags to add for towing purposes. There is no set make directly for my Lexus GX460 but both Firestone and Air Lift appear to make ones that may work. Can you confirm which model would be best fit.

I have a solution for your towing needs, however, there are currently no air suspension options for your 2017 Lexus GX460.

If you are wanting to extend the life of your vehicle's suspension and reduce body roll, I would look into rear suspension enhancement.

I recommend the Timbren Rear Suspension Enhancement System # TTORSEQ. The hollow rubber springs sit above the rear axle to help level your vehicle and absorb shock, providing a much safer and more stable ride when hauling heavy loads. This kit can safely handle up to 6000lbs.

This setup is extremely easy to install, requiring no welding or drilling. You simply replace the factory bump stops with these rubber springs using the included hardware.

Now that you know your options for suspension enhancements, let's move on to the best way for providing stability and leveling the vehicle when pulling a trailer.

Generally, a weight distribution system will be necessary when towing a trailer with a gross weight greater than 50% of the towing vehicle's gross weight. This will help level the vehicle and trailer, providing a much safer ride and also helps prevent trailer sway. You first need a class 3 or greater receiver hitch; I would go with the Curt Class 3 Trailer Hitch Receiver 2" # C13043 if you do not already have one. This has a max tongue weight of 500lbs and max towing capacity of 5000lbs.

Now for the weight distribution system; I recommend the Strait-Line Weight Distribution System w/ Sway Control 10,000 lbs GTW, 600 lbs TW # RP66082. This has a tongue weight range of 200-600lbs. Based on the towing capabilities of your vehicle and the 500lb tongue weight of the hitch mentioned above, this weight distribution system will likely be what you are looking for. However, we do have weight distribution systems that offer more or less weight.

You will also need a hitch ball for the weight distribution system. For 2" ball I'd go with # A-90, and for 2 5/16" go with the # 19286.

I have attached demonstration videos below.
