Sprinter Suspension Upgrade Package A for 3500

This is the best performing Sprinter suspension upgrade we have put together, based on both price and customer testimony. We include all top brand names in suspension performance. All three major areas of your Sprinter suspension are addressed, creating a great balanced package. Every item in this suspension package is direct fit with minimal labor involved and no drilling or other major modifications. 

The package includes rear progressive Sumo Springs made from micro-cellular urethane, a 1.5 inch rear sway bar*, Koni FSD self adjusting shocks and struts, or Koni Special D manually adjustable shocks and struts.

The Sumo Springs are a micro cellular urethane product designed to help reduce rear-end sag and stabilize sway. They are a progressive spring with a very soft initial engagement. That means that as more weight is added, the harder they get and more they push back, providing support and control when you need it without affecting the factory ride when unloaded.  

Koni shocks and struts are used to enhance the damping of your Sprinter - which slows suspension movement. The Koni FSD is a frequency sensing damper (shock absorber) that will automatically adjust according to road conditions, without electronics. Designed to offer both stability and comfort, which is hard to obtain with standard pre set shocks. 

The sway bar will be the largest (1.5") direct fit aftermarket bar available in the industry made by Hellwig or Roadmaster depending on application.

This suspension upgrade really addresses a wide range of improvements. Whether you have a Winnebago View, Itasca Navion, Era, Reyo, Airstream, Roadtrek, or any other Sprinter based Class C, Cab Chassis, or 3500 van chassis, we have you covered. Enjoy a more relaxed ride and surer feel. This is a great suspension package and can improve many handling characteristics.
