Question:

I am debating between the Sumo and Timbren suspension add-ons for my 2012 Ford Flex. Does one perform better than the other when it comes to pulling a trailer and utilizing a load disbursing / sway hitch?

I personally prefer the Timbren Kit # TFRFLX over the Coil SumoSprings # CSS-1069R for your 2012 Ford Flex basically because the Coil SumoSprings are kind of pressed into place and then secured with zip ties to help keep them where they need to be while the Timbrens are secured in place by a bolt.

Both will do a great job at adding support to your suspension but in this comparison I'd go with the Timbren kit.

Pro Tip - Make sure that your weight distribution (WD) system is rated properly for your towing setup. Ideally you shouldn't need suspension enhancement on your vehicle if your WD is doing its job properly (but is isn't necessarily a bad thing, especially if your vehicle needs some extra support while not towing). Make sure that the loaded tongue weight of your trailer plus any weight behind the rear axle of your Flex should fall in the middle of the tongue weight range for your WD system. Also be sure your trailer is loaded properly with 10-15% of the loaded weight being on the tongue.
