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
