Hey Charles,
For air springs we currently only offer the Lippert Center Point by Trailair Air-Ride Suspension Upgrade # LC1565391. This system can help improve ride quality by reducing road shock and chucking. It does require standard hangers and the hangers must be spaced either 29 1/2” or 30 1/2” apart, otherwise you'll need to redo your suspension in order to complete the install.
We also offer jounce springs that can help in the same way, just without the customization you'd get from adjusting the psi. The correct kit for these would depend on your axle capacity and whether your leaf springs are hung above or below the axle tube:
Overslung:
3k - 5k # TSS-107-40
5k - 8k # SS26MV
Underslung:
3k - 5k # TSS-106-40
5k - 8k # SS33HR
I'm assuming your trailer axles are in the 5k to 8K range but you'll want to check them for the axle tag to confirm. I've attached some videos below to show these products being installed and how they work to give you a better idea of what you'd like. If you have any more questions just let me know.
