Hi Jennifer,

Manufacturers do tend to forget about the suspension/ride quality when it comes to building these RV's so this is a very common issue. Luckily SuperSprings International has just what you need with their SumoSpring jounce bumpers. Their microcellular springs offer load leveling support and a much needed cushion for the suspension to help eliminate the bounce or jarring bang when your axle hits the smaller/stiffer factory bump stops. These springs are completely maintenance free so once they're installed you're good to go.

For the front suspension you'll want the SumoSprings Solo Custom Helper Springs # SSF-106-47 and for the rear the SumoSprings Maxim Custom Helper Springs # SSR-106-47-1. The rear jounce spring will have some fitment requirements (listed below) depending on the model of the motorhome.

-Requires 7 inches of minimum clearance from sidewall of tire to frame on dual rear wheel models
-Jayco models must not have J-ride installed. J-ride interferes with mounting brackets.
-Does not fit Thor Motorhome models

If you can't use the rear springs then you'll want to go with the SumoSprings Solo Custom Helper Springs # SSR-130-47 instead, which don't have the same fitment stipulations. I have a similar style to this one on my truck and the difference it for body roll when making turns was night and day.
