Recommended Suspension Enhancement for 2021 Toyota 4Runner Limited

Question:

Hello, I have a 2021 4runner Limited and I need to tow my 2006 Jeep from CO to SC using a U-Haul car carrier. The Jeep weighs around 4000lbs and the trailer weighs around 2000. My 4runner sags pretty badly when I tow our 3,000lb camper, so I know it isnt going to do great with a heavier load. Do you recommend a spring helper or airbag system? I know there are 2 major brands of spring helper and I dont really know anything about airbags.

For suspension enhancement on your 2021 Toyota 4Runner limited I recommend the SumoSprings Solo Custom Helper Springs - Rear Axle # SS68DR. These are maintenance-free and will help keep you level. They use progressive load control so they springs compress according to the weight of your cargo.

These SumoSprings have a capacity of 1,400 lbs and come with a limited lifetime warranty. The # SS68DR will also have a minimal impact on your unloaded ride quality.

I have attached a review video for your reference.
