How To Reduce Vehicle Sag While Towing 2015 Ford Expedition W/ 3

Question:

Might be a silly question but I'm about to install a ReadyLift 3inch leveling kit on my 15 Expedition EL XLT. The past times I've towed I noticed it sagged a little which has brought me here. I was just curious if there is any issue with me using this coil sumosprings with me also having the lift spacers.

The Coil SumoSprings Custom Helper Springs part # CSS-1168R are compatible with the ReadyLift spacers you have on your 2015 Ford Expedition and will also work well to help reduce the rear end sag on your vehicle while towing a loaded trailer or heavy load. The SumoSprings are the only suspension enhancement option we have for you at this time but nonetheless, are still a great option.

The spacers are designed to help reduce the amount of compression that occurs on the vehicle's coil springs while loaded. The reduced compression of the coil springs while loaded will in turn minimize the amount of sag you have while towing/hauling.

You will not find a suspension enhancement option that is easier to install than these spacers. All you will need to do to install them on your Expedition is jack up the rear end of the vehicle where the wheels are off the ground. You can then maneuver the spacers between the coils on each side. The only thing you will need to be careful of is the number of coils below and above each spacer. This will need to be the same on both sides.

I have attached a review video of the SumoSprings in addition to a photo of them installed on a similar vehicle for you.
