Question:
I have a 2017 Ford Expedition, and pull a 6700 lb trailer about 800 lbs tongue weight. I have the max tow package, and the Exp pulls great. I also use an Equalizer hitch, but have had trouble getting the Equalizer to correct for the squat on the Exp. As I understand the independent rear on the Exp just doesnt have as stiff of a bottom-out point. If I over-set the Equalizer, Im able to get things more level. However, it causes issues freaks out traction control systems on the Exp. I think this is because the anti-sway functions on the Equalizer are really cranking hard when its over-set like that. Any ideas on how to set it up, or possibly an alternative to the Equalizer that would help to get things more level without becoming too rigid? Thanks!

For starters, I would first make sure that the Equal-i-zer Weight Distribution System you are using is properly rated for the total touge weight (TTW) of your towing setup. In order to find the TTW of your towing setup you will need to add the tongue weight (TW) of your loaded ready to tow trailer to any cargo stored behind the rear axle of the tow vehicle. The best way to do this is with a tongue weight scale like part # e99044. If your TTW is between 600 lbs - 1,000 lbs then part # EQ37100ET would be correct for you but if your TTW is between 800 lbs - 1,200 lbs then part # EQ37120ET would be a better fit.
Now in regards to setting up the system, you will first want to take a measurement from the ground to the top of the front fender wheel well while uncoupled from the trailer. You will then want to setup the system and couple the trailer to the hitch ball and then repeat the above process. Adjust the system until you are about halfway back to the stock ride height in the front. For example, if the distance from the ground to the top of the front fender wheel well is 30" while the trailer is uncoupled and 32" while coupled. You will want to adjust the system until the front is back to around 31".
Another issue may be the placement of the head in regards to the shank. According to my contact at Equal-i-zer you will want the hitch ball to sit about 1/2" to 1" above the trailer coupler while level. Once this is done and you have adjusted the system using the above steps, this should fix your issue. However, if you are still experiencing sag then you may want to look into suspension enhancements like the Coil SumoSprings Custom Helper Springs part # CSS-1168R for 4WD models.
