AirLift Primary Air Suspension System

[u2plt]

Has anyone installed the AirLift Primary Air Suspension that completely removes the rear spring system? If so what are the results? Is this the system that will take out all the problems with cement joint hard bounce? The Kelderman keeps the original springs and costs about half as much. I see that Camping World sells the Airlift Primary Air with Presidents membership at a little discount.

What you want to do with the Kelderman system is to hold down the helper springs with some spring retainers and put them into constant compression within the spring pack. That will stiffen the springs up and allow less spring compression with a load which will force the road action through the air springs. A better ride and a more level bed when loaded.
