This is our Suspension Upgrade Package B+ for the Promaster vans and cab chassis. It fits the 2014 to 2025 1500, 2500, and 3500. It is similar to one of the most popular combinations we have sold over the years. This one is a little different since it does not include a rear sway bar upgrade, but all parts fit up to 2025, where there as been some variables with the sway bars on the later years. Now you do not have to worry about that, or you may just not want to upgrade the sway bar. 

The Suspension Upgrade Package B+ for Promaster vans includes front and rear progressive SumoSprings made from micro-cellular urethane, Koni FSD rear shocks and front struts.

The Suspension Upgrade Package B+ includes all top brand names in suspension performance. All 4 corners of your Promaster suspension are addressed with both spring assist and damping, creating a nice road handling package. Also, every item in this suspension package is direct fit with no drilling or other major modifications. 

The Sumo Springs are the medium density material. SumoSprings are a micro cellular urethane product designed to help reduce 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. Unloaded vehicles will have little or no engagement with the SumoSprings until rocking or bouncing occurs. 

The Koni FSD's are a frequency selective damper that will automatically adjust according to road conditions, without electronics.

This suspension upgrade really addresses a wide range of improvements. Whether you have a factory built RV, custom RV, work van, or your Promaster van is a weekend adventurer, we have you covered. Enjoy a more relaxed ride and surer feel. This is a great suspension package at a reasonable price and can improve many handling characteristics.
