Hey Craig, thanks for reaching out!

The Coil SumoSprings Custom Helper Springs # CSS-1145R will help give some extra support to your 2022 Toyota Highlander, but I don't recommend swapping out OEM suspension parts unless they look like they're worn out.

Some other things to check are your weights. Make sure your Highlander isn't being overloaded, and double check that the tongue weight of your trailer is within the recommended 10-15% loaded weight of the trailer for best towing.

Let me know if you have any other questions!

Hey Craig, how did things go after adding the Coil SumoSprings to your Highlander? Did they help level out the rear when towing your cargo trailer? Your update could make it easier for others dealing with the same sagging issue.
