Question:
I have a 2021 Lexus GX 460 with the premium trim package. The vehicle does not have a factory air suspension system. According to your site the Air Lift 1000 helper air bags are not compatible with my 2021 GX. Other sites I have looked at indicates it is. Im trying to determine for sure before I purchase. I have contacted the manufacture to check the compatibility, but have yet to receive a reply from them. Can you provide some clarification? Thank you, Mark W

Hey Mark, thanks for reaching out. I double checked with Air Lift and unfortunately, they do not offer a helper spring kit for the 2021 Lexus GX. They have a kit for the 2010-2019 GX 460, but that kit will not carry over to the later model years.
If you need to beef up the rear suspension, we do have products for that. What I recommend is the following:
- SumoSprings Solo Custom Helper Springs - Rear Axle # SS68DR
These are rubber helper springs, and they have a capacity of 1,400 lbs. This will help support the rear of the vehicle. They will help reduce sagging and they will help add stability while you are hauling. They are an easy bolt-on installs.
Will you be hauling a trailer with your Lexus? What kind?

Hey Mark, how did things go with the SumoSprings on your GX 460? It’d be great to hear if they gave you the rear support and stability you were looking for. Your feedback could help others deciding between air bags and rubber springs for similar setups.
