Can Multiple Coil SumoSprings Be Used On a 2021 Ford Expedition

Question:

Can you double up the coil springs to make even more stout in the rear when hauling an RV? My 2021 Ford Expedition has too much sag in the rear end when hauling my 20 foot toy hauler. I am wondering if only the one set will keep the rear suspension from sagging too much.

The Coil SumoSprings Custom Helper Springs for Coil Spring Suspension part # CSS-1168F which are a fit for a 2021 Ford Expedition will help the coil springs from compressing which will in turn prevent sag/squat. There will only be one spacer per side needed. It would not be advised to install more than one per side as they would likely not fit and the ride would be very harsh if done so.
