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!

Out of those two hitches, I recommend the Curt Hitch item #C99FR over the item #C45CR for your 2022 Toyota Highlander XLE. The tongue weight capacity for both will easily accommodate a cargo carrier but the item #C99FR has a far better profile once…

Hey Joseph! The Curt item #C45CR requires you to disconnect an exhaust hanger temporarily, but it gets reinstalled a couple steps later. It's just to get the hitch to the mounting bolts behind the muffler. This hitch is custom fit for the 2022…
