Is It Normal for SumoSpring to Make Contact With Frame with Just Vehicle Weight on Suspension

Published 04/06/2022

Question:

I noticed on your video of the install of the rear sumo on a ford E 350/450 RV that after lifting the frame the sumo was making contact at the top and bottom even before removing frame jacks. So, what Im asking am I to assume once vehicle is lowered there is a constant compression on the sumo spring say 1/2inch to 1inch ???

It isn't out of the ordinary for the SumoSpring kits like the part # SSR-130-47 to make contact with just the weight of the vehicle on the suspension. This is more true for RVs where the weight on the chassis varies more with how it's configured.
