How to Fixing a Sagging Rear End When Towing w/ a 2025 Toyota Sienna XLE AWD

Updated 06/12/2025 | Published 06/04/2025

Question:

Hello I have a 2025 Toyota Sienna XLE AWD hybrid and I was wondering if the helper springs that you have will work with that vehicle to help with rear sag when loaded down or towing? I’m talking about the ones that kind of fit in between the existing coil springs?

Hey Brian. I am sorry but the Coil-Rite Air Helper Springs item # F4155 you referenced will not work with the AWD models of the 2025 Toyota Sienna XLE.

The only option I have to help you with the sagging you're experiencing is a weight distribution system. If you could tell me how what trailer you have and how much your trailer weighs I would be happy to make a recommendation for you.

I was actually talking about the sumo coil spring helpers the CSS-1168R will these be ok with my sienna?

@Brian No, they will not for the same reason. The Coil SumoSprings Custom Helper Springs item # CSS-1168R do not work with the suspension on the AWD 2025 Toyota Sienna.
