Recommended airlift for 2019 TRD Offroad?

Any experience and recommendation for airlift on stock could (no lift) for some towing off road? I see few install the Airlift 60809 1000 but on every site it says it doesn't fit.... Just want to make sure.
TIA

 

I have no help, but welcome to the forum.

 

I towed boat home from N. Minnesota back to SW Missouri last year. By the end of the trip, my nose was in the air and my rear was sagging.
Reading around Firestone Airbags for the rear are the way to go if you're towing long distance.

For a short couple of miles to the lake and back, they are not needed.

Note with spec-ing some of this stuff - if you have a 2020 4Runner - it uses all the same springs / shocks as the earlier models. So try going down a few model years.
