Hellwig and Koni 3500 due in Dec

Sprinter Suspension Upgrade Package A for 3500

$ 1,408.47

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. Also every item in this suspension package is direct fit with minimal labor involved and no drilling or other major modifications. 

The package includes a rear progressive Sumo Spring made from micro-cellular urethane, a 1.5 inch rear sway bar*, Koni red shocks and struts, or Koni gold FSD shocks and struts (2002 to 2006 early body Sprinters will come with the red Konis). 

The Sumo Springs are an airless air bag system that work with your factory spring by adding load assist. Similar to a conventional air bag system but manufactured with closed cell urethane which creates thousands of small air bags within the unit. These are maintenance free, durable, and soft riding. We offer the newest wider version of the Sumo Spring.

Koni shocks and struts are used to enhance the damping of you Sprinter. The Koni FSD gold is a frequency sensing damper or shock absorber that will automatically adjust according to road conditions, without electronics. Designed to offer both stability and comfort.  The other option for you Sprinter is the adjustable red Koni Heavy Tracks shock absorbers which have an adjustable rebound setting, and we can make an adjustment recommendation based on your vehicle information. On early body 2003 to 2006 the package A  is only available with the red adjustable Koni and not the FSD.

The sway bar is the largest direct fit aftermarket bar in the industry made by Hellwig.

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.
