Semi-Air
For motorhomes and vans the terms semi-air suspension, air assist, auxiliary air suspension or load support are all used, depending on the company or country, but they all actually mean the same thing.
Well, air assist (as we’ll refer to it from now on) predominantly relates to vehicles with rear leaf springs, rather than coil springs. In an air assist system, an airbag is used in addition to the original suspension (hence ‘assisting’ it).
Air assist lifts the suspension up, thus recovering the lost motion from the vehicle’s weight-induced sag and stabilising the vehicle due to the additional support. It also creates extra clearance at the rear to overcome grounding. Recovering this lost suspension range allows the suspension to function correctly and better irons out any bumps.
