How to Select Weight Distribution Hitch to Correct Sag in 2003 Ford Expedition

Question:

I am not seeing where the 2003 Ford Expedition is explicitly listed as a valid use for Item # CSS-1168R Sumo spring to help reduce sag. Looking to find out if this is an option for me. If not, do you have another recommendation? Thanks!

We do not show any confirmed fits for suspension enhancement kits for the 2003 Ford Expedition; I checked directly with SuperSprings and Timbren too and they have no kits for your vehicle. But there is another more effective way to help level a tow vehicle if trailer tongue weight (TW) is the cause for the rear-end sag.

A weight distribution/sway control system (WD/SC) like Equal-i-zer # EQ37100ET will actually push some trailer TW forward onto the front axle which levels the vehicle and restores steering and braking performance, both of which require solid traction between the front tires and the road. You can check out the linked video and article for more on how these system work and how to select one.

The key to selecting a system is knowing the total TW of the towing setup, which includes the actual loaded trailer TW (that can be measured with scale # e99044) and the weight of any cargo in the vehicle that sits behind the rear axle. This total combined weight figure should fall in the middle of the system's operating range. The example system # EQ37100ET works for total TW from 600- to 100-lbs so it would be perfect for total TW of 800-lbs.

If your sag is a result of trailer TW then a WD/SC system will improve your ride quality much more than a set of rear axle helper springs.
