RV mechanic is mystified that something so simple can improve steering so much. All but eliminated the constant micro-corrections (and often not so micrco) and wandering I experienced with my RV. Easily installed.

Helps stops the rocking and swaying especially when going around corners. Very pleased with them.

These are put on a Econoline E350 high top with full camper build. The vans ride was great before(or so I thought) installing but I was adding a 300lbs motorcycle on a hitch carrier. Now the van rides better then before. When driving slow semi-off road routes sometimes Iād experience Left and Right body roll/bounce? That same road with the supersprings rides so much smoother even with a motorcycle in the back.I wish I also add them to the front as well.

Put these on front (also bought and installed the rear Sumos as well). Really seems to have corrected The overall ride of our FR 31 foot Motorhome. I plan to update after a few more trips after this virus goes away.
