Question:

I read your below response which guided the owner to The SumoSprings, part # SS78DR would be a better choice because theyre made of a softer material that would provide a significantly better ride quality. Helper Spring Solution for 2021 Toyota 4Runner Towing 3700 lb Travel Trailer We just towed for the first time our 4,000lb 500lb tongue wt. camper with a new 2021 4WD 4 runner SR5. We had a 2007 FJ cruiser previously with heavy duty shocks on the back dont know anything about the shocks. with the 4Runner, the back would wallow up and down on bumps and i noticed the car would roll a little side to side, creating some sway on the camper more than i had when using the FJ. will this suspension help the up and down wallow and the side to side rolling that we are experiencing with the stock suspension.

Yes, the SumoSprings Solo Custom Helper Springs item # SS78DR work independently from each other to compensate for off-center loads and reduce body roll during turns. These will help your 2021 Toyota 4Runner stay level when towing as well.
