Question:
Hi guys...have a 2020 4Runner with a 3 lift, have a question re rear suspension air bags and/or Sumo springs to help reduce sag when towing. Im guessing either system will need some kind of spacer to compensate for the extra lift, correct? Unloaded, I have 9 3/8 from the bottom of the frame to the top of the rear axle. Any help would be appreciated. Thanks Anthony

Hey Anthony, you would want the Sumosprings kit part # SS68DR that is a confirmed fit for your 2020 Toyota 4Runner and then since you have a 3 inch lift you'd need a quantity of 6 of the spacers # A25723-90AH00 to take up that extra space created. There isn't a similar solution for the air bag system since they all install in the rear coils.

Hey Anthony, how did things turn out with the SumoSprings and the spacers on your 4Runner’s 3-inch lift? It’d be great to hear how the setup handled your towing load. Your update could make it easier for the next person working with a similar lift.
