Question:
What suspension product is recommended for a 2022 Toyota 4Runner?
asked by: Mike T
Expert Reply:
The Firestone # F4135 Coil-Rite air helper springs you'd looked at are a fit for your 2022 4Runner, but unless the load you carry in the cargo area or the trailer's tongue weight will vary to a large degree, you really won't need the adjustability provided by an air helper spring system.
I prefer a bump stop replacement like the SumoSprings # SS68DR. The SumoSprings won't affect your vehicle's ride until there's some compression applied to the rear suspension. With this system you won't need to worry about anything leaking.

Hi Mike, you mention tongue weight varying. I will be towing a side by side and that along with the weight of the trailer will be just over 4000 pounds. I am looking for a suspension support to avoid sag but also ride well when not towing. I have looked at both sumosprings and firestone airbags. Which one is best for my application and will provide a nice ride when not towing? I am also looking at weight distribution hitch with sway control. Will this be a good combination or cause any concerns? Some use one or the other and some use both. I did see one 4Runner 5th gen owner say a WD hitch was not recommended for his vehicle which I have yet to see.
