Jerry McDonald –
As I was researching add on spring solutions to correct rear-end sag in my Mercedes Sprinter camper van, I came across SuperSprings and called their customer service. They were very helpful in helping me make the decision on what product that best fit my van and needs. Order and delivery was worry free. Installation was straight forward except for the confusion about the removal of the factory sway bar bracket. The written instructions had the brackets being removed, but the videos don’t mention the step. The installation took a little over an hour and now my van is level as it raised the rear-end an inch. The ride is much improved with less sway. I may end up getting the Sumo Springs for the front.
