Top Drive Air Suspension for Automatic Automatic Rear Air Suspension for RAM Trucks Promaster 2013>

Top Drive Air Suspension is an ideal addition to any commercial van or motorhome which is consistently heavily laden. It is an air assist which will return the ride height to where the manufacturer intended it to be, rather than down on the bump stops. This means your suspension will last longer and save you money in the long run. The lift attained on the suspension positions the shock absorber at the optimum height and therefore improves damping.

Fitted with the comfort kit it allows the driver to adjust the ride height, this enables adjustment on the ride comfort, reduce vehicle roll and level off-centre loads.
