Smoothing the ride

[Willieboy]

I own a 2018 Winnebago Sunstar and I'm considering adding Sumo Springs to the suspension (F550). Is anyone familiar with this product? I've been told that they reduce the more extreme bounces and also lessen the drift/float of the front axle (functions like a sway bar?)

We have a 2003 Newmar W22 workhorse chassis. Had very bad porposing at dips, bridge transisitons, etc. Put Knoi shocks on and it made tremendous difference, handled better and no more porposing, felt much safer. Still had what I would call a "slam" at some expansion joint, pot holes, etc. Put Sumo springs on the front and now still have the noise at the expansion joints, etc, but not the jar. Those two things were a game changer for us. Good luck.

I thought I'd update on the modifications I made to my 2018 Winnebago. I replaced the original shocks with Bilstein B6 shocks, added Sumosprings to the front suspension and made the "cheap handling fix to the front sway bar. The ride is greatly improved. These were all done at the same time so it isn't clear which mod made the greatest improvement. However, in combination they made a huge improvement.
