Recommended Suspension Enhancement for a 2019 Toyota Highlander that Sags When Pulling a Trailer

Updated 09/02/2025 | Published 06/30/2025

Question:

I have a 2019 Toyota Highlander that seems to sag quite a bit when the camper trailer is loaded. We have a weight distribution hitch already and still the SAG is pretty severe. Do you have any recommendations for suspension leveling or enhancements for the rear vehicle?

Hey Kyle. The only suspension enhancement I have that will help with your Highlander's sagging issue is the Coil SumoSprings Custom Helper Springs for Coil Spring Suspension item # CSS-1145R. These insert in your rear coil springs and limit their range of motion.

What kind of weight distribution hitch do you have and how heavy is your trailer? I'm wondering if you have an underrated weight distribution hitch or it's not set up correctly.

Hey Kyle, did the Coil SumoSprings help with the sagging issue on your Highlander? I'm asking because your experience could help others dealing with similar suspension challenges.
