I tow a travel trailer that fully loaded would be 9k,so maxed out! I am waiting on my 5100s front and rear, and with those new LT tires. I just put on the sumo springs in the back and they are a great improvement for rebound damping. The back of the car does not oscillate nearly as much. Highly recommend them for 150bucks. I think with all three things my towing will be acceptable for me.

Looks like you have Expy Max from the pic is that correct? I'm looking at a travel trailer that would max out at 8k lbs. Good to know what you've done. I'm going with the 5100s also, but not sure about sumo springs yet. I'm waiting on the rear sway bar, hoping for April delivery!

Yep, MAX with max tow. I just ordered the sway bar, the sumos for 160 are great, just to help with the oscillating.

Expedition has struts on all four corners past 2003? Anyway I tow and my factory struts were not up to the task. 2014 EL King Ranch 4x4. So I upgraded to Goodyear ultra terrain tires. Bilstien 5100 struts on all for corners set to the highest position and fords latest revised coil for all four corners. I ordered a hellwig sway bar that is going to take months to get here, but the ride is great! Perfect for towing or not.A760DEAA-63C3-4209-8429-B62EA44E7A1B.jpegD950980E-9D78-439F-8778-549F601B2925.jpegB2968806-98FF-4E8D-9EDD-81F71E572590.jpeg

Is the oscillating side to side or front to back?

I tow a car hauler with a combined weight of around 5000 - 6000 lbs (depending on cargo) with the OEM tow package, stock CCD suspension, and Weight Safe hitch with no oscillation.

I have Sumo Springs and swaybars still in boxes because the side to side oscillation in the Max with just passengers is vomit enducing. I'm trying to decide which set to try first.

So my oscillating is forward back due to the very heavy trailer. The sumo springs really helped that. I have the rear sway bar to install to help with side to side. Today I get to pickup my expo that just got bilsteins 5100 all around along with e rated LT tires

Thats the sway bars job. Its absolutely embarasing with the factory bar. My friend rode with me one day and said WTF is wrong with your car, its bobbing left and right so much that I'm getting sick. Its pathetic they allowed them to leave the factory on such tiny sway bars.

That confirms what I was thinking. Thank you.
