$ 385.00
This product is unavailable

The Ram Promaster van Boss rear air bag system comes with everything necessary for installation. Boss air bags are a load assist kit and are the Australian equivalent to the Firestone air bags. We think this is the best air bag kit on the market for the Promaster van. See comparison chart below. Complete bolt on system with everything required to adjust air manually via schrader valves. You can air each bag individually and there is an optional on board compressor kit available.

Use the minimum amount of air pressure possible to offer assist, and do not exceed GVWR. Do not overload your vehicle or over-inflate the air bags as this could cause chassis damage. Buyer assumes all risk regardless of manor used.
