Question:

I have a stock 2019 Toyota 4 Runner. Using a roof rack I want to load it to 700 . I am going to tow a No-Bo 16.1 which empty is 2889, but loaded it will weigh 3545. So 700 + 3545 = 4245 total GVW. The maximum towing capacity for the 4 Runner is 5000 which leaves my safety margin at about 15 well within the 10 min. So to my question: I like the air bag solution since it is easy install and very adjustable. I am thinking about using the Sumo Spring ALSO, for rougher roads, long trips, increased stress relief off the suspension. My thoughts are that it would work very well for my needs. Any thoughts from you all? Am I correct? Thank you!

Hey Lynn, we generally don't recommend running more than one set of suspension enhancement on a vehicle because the performance of the two kits together has never been tested and most likely if you need two you are overloading things. I would first try the SumoSprings kit part # SS68DR though as that is most likely going to get you exactly what you are looking for and then from there decide if adding more support with an air bag setup like the Firestone part # F4135 is needed.
