Recommended Suspension Enhancement for a 2021 Ford Expedition

Question

Question:

Hi, I purchased a 2021 Ford Expedition. I tow a 20 foot toy hauler trailer. I notice the rear suspension compresses a bit while under load. I am looking for a solution to lift the rear to keep it more level while towing. The Ford Expedition rear suspension is coil with piston rods going down the middle of the coil. All the air bags for coil suspension seem to not account for the piston rod. Is there a solution, or what would be the best solution for this to provide lift to the rear suspension under towing load? Thank you for your assistance!

The only suspension enhancement option we offer for a 2021 Ford Expedition is the Coil SumoSprings Custom Helper Springs for Coil Spring Suspension part # CSS-1168F which installs in between the coils. There are no air bag options due to the strut inside the coil spring. The SumoSprings will work well to reduce sag/squat while towing or hauling. They install easily and can be removed when not in use.

Yes, you can use the Dexter E-Z Flex Suspension Kit #K71-652-00 with 31 inch axle spacing because these equalizers are a match for your current Equalizer #TREQ104. We have contacted Dexter about this previously and so long as the equalizers are the…

Hi Jason; it looks like your 2022 Yukon towing capacity is 7,500-7,900 lbs so I'm not surprised you're getting that rear sag. The best solution is going to be a weight distribution hitch. This will keep you level and also help reduce trailer…

For the SumoSprings #SSR-209-40 for your 2012 GMC Sierra 1500 4x4 the springs will reach their 1,000 pound capacity at 50 percent compression. That means that there could still be some squat until the spring compress enough to stop it. But at the…

Hey Michael, Adding to or enhancing your suspension would help with body roll and side-to-side movement. When it comes to anti-sway bars you'll want to go with whichever is the thickest. The Hellwig #HE74GR is 7/8" thick so you can measure…

For your 2000 Jeep Wrangler (TJ) I recommend Timbren front helper springs #TJFTJ. These springs will provide better support than the Coil SumoSprings. Air bags could be used, the durability is not an issue, but for this application I find air bags to…
