While installing air ride is doable, it would involve quite a bit of work. I certainly would consider softer springs. For air ride you would need an air compressor and a reservoir. The leveling valve maintains constant ride height by inflating and deflating the bags as needed.
And you need to measure to see if you have enough room for everything. I have several F-liner cut offs that I bought for the 3rd members. There's a lot of bulk there to squeeze under an LCF.
