Promaster Suspension Upgrade Package B

Our popular Suspension Upgrade Package B is now available for the Promaster van and cab chassis and fits the 2014 to 2021 1500, 2500, and 3500. It is one of the most popular combinations we had put together for the Sprinter van with many sold over the years and great customer feedback.  Not for Promaster vans with rear coil springs. 2022 and 2023 is compatible only with the 2500 and 3500 models and vans must have a factory bar on them already.  The Suspension Upgrade Package B for Promaster vans includes front and rear progressive SumoSprings made from micro-cellular urethane, rear upgraded sway bar (2022 to 2023 will receive a 1.25 inch rear sway bar, 2014 to 2021 will receive a 1 1/8 inch rear sway bar) and Koni FSD rear shocks. 2022 to 2023 vans must have a factory sway bar.  The Suspension Upgrade Package B is a variation of the popular Suspension Package A we have been using on the MB vans for many years. Package A is also available for Promaster, but does not include the 118" wb
