Sumo and Hellwig

Installed Sumo Springs and drove 1800 miles. Some improvement in the handling, not huge. Installed the Hellwig sway bar (my unit is a 2015 so not factory equipped with the larger bar). Drove about 100 miles and a noticeable improvement in handling. Very happy with the purchase and an easy installation but very hard to loosen the factory bolts on the axle.
Still rocks and rolls on parking lot entries but not a real problem.

Just rear, the smaller ones.

Now finish it off with Koni or Billstein Shocks and you'll be there

Adding the front sumo springs and upgraded shocks will make a significant improvement in rocking and handling. I went with the Bilstien heavy duty shocks. Easy to install or have installed. Original rear shocks are very soft when you compare them off the vehicle. My Solera handles very well with all the upgrades. Pleasure to drive on the highway without the constant fighting of wind gusts and passing trucks.

Does anyone have a recommendation for a good service center in the Denver area to assess and recommend the best course of action? My 2016 MBS2401W swings and rolls way too much and I don't have the knowledge to determine myself what to do.

Bilstein, Helwig and Sumo will answer your problem providing your tire pressures are correct. Around an hour of labor by a pro. the entire operation cost me less than 900.00. 10,000 miles on installation, no problems

Atlanta to Oshkosh

Recently installed the soft Sumos on top of previously installed Koni FSD shocks and Helwig sway bar. First long trip Atlanta to Oshkosh. The Sumos help, especially when moving slowly over certain types of bumps. Coach is more stable when parked without stabilizers down, obviously a side effect of Sumos having contact between chassis and rear axle.

Thanks. Did you consider airbags as an alternative or was springs the only route?

I understand airbags probably are an overall better solution to ride quality issues - but given the issues we had with component failures, I did not want to add yet another active component to a somewhat unreliable MH.
