Suspension Enhancement Recommendation 2021 Toyota 4Runner Nightshade

Updated 08/25/2025 | Published 08/22/2025

Question:

I have a 2021 4Runner Night Shade. I am getting too much rear slump when hauling a decent load. I’ve had issues in the past with getting parts that will fit because of the night shade edition, such as power running boards. I am looking for a solution to the rear slump while towing that will work with the night shade edition. Thank you Nelson

Hey Nelson, we have the SumoSprings Solo part # SS68DR that is a confirmed fit for your 2021 Toyota 4Runner Nightshade. I was able to confirm that your Nightshade has suspension that is compatible with this kit so it would be a great option to reduce sag. I like the SumoSprings kits because you get the best blend of suspension support and ride quality without having to mess with maintaining air pressure like air bag kits require.
