For your 2021 Ford E-450 Super Duty 25' Class C Motorhome I highly recommend the SumoSprings Maxim Custom Helper Springs - Rear Axle # SSR-106-47-1 as it offers 4600lbs of support to the rear suspension while also absorbing road shock and minimizing sway. If your Motorhome has dual rear wheels you will need to verify that you have at least 7" clearance between the inside edge of the tire and the frame.

To get the best results I do also recommend # SSF-106-47 for the front suspension which will give you 1000lbs of support to your front suspension which will give you a smoother ride and also help minimize sway.

I included videos for both of the products mentioned for you to take a look at.

Hey Jeff, SumoSprings do not need to be touching the axle when unloaded. Having a bit of a gap while unloaded is totally normal. Giving your axle a bit of wiggle room before engaging the jounce spring will give you a bit more of a comfortable ride.…
