Question:
Hi I have a 2021 expedition max and tow a travel trailer and a boat at different times. I’m trying to decide what would be a better expenditure to improve the towing of my expedition max. I’m trying to decide what would be better. Sumo springs or a hellwig sway bar. Which one would provide a better towing experience with my expedition max. Thanks.

Hey Dan! What are you experiencing when you tow your trailers? If you're getting rear sag with a little bit of body roll I would get the Coil SumoSprings # CSS-1168R for the additional suspension support. If you're primarily getting a lot of side-to-side movement and it feels like you're unstable I would say the Hellwig Rear Anti-Sway Bar # HE74GR is the better choice. I use a 2020 Expedition for towing and the biggest problem for me is rear sag. However, that may be different for you depending on your trailers and boat.
