Air Lift 1000 Series front air bags.

When I installed the 2012 front axle, I wanted to install Super Springs

but they seemed to be back ordered everywhere. The coach has always sat a little low in the front. It takes a leveling board to be level on a level site. Front axle weight is about 4500.
Super Springs unavailable, I went with Air Lift hoping to pick up a little more front end ride height. Maybe half an inch, but they have improved the ride. Better over dips in the road, and a little more stable. The suspension seems quieter than before. But... it now has the 2008 and newer Radius Arms with a different bushing design.
Summary: There are other products that do more for ride height. Some day I may try Super Springs.
