Since the Sedona is my work van and carries a lot of weight on a daily basis, the rear end sags quite noticeably. So I ordered these Firestone Coil Rite Airbags Being a somewhat rare vehicle, aftermarket parts are somewhat scarce for the Sedona, so these were the only airbags that were readily available. I got them for just under $100 with coupon code. Any experience with products similar to this? I plan to hook each one up to its own feed line, so I can fine tune each one to the proper ride height, as I'm sure my load is never distributed quite evenly. These airbags go inside the rear coil springs, and the factory bump stop gets removed. The van has a separate spring and shock independent rear suspension, FWIW.
