I have cheap Air lift system for the last 3 years. Mine are 60755 which are the tallest bag they make that fit LC coil spring. I would not recommend this though unless you have fixed rate spring that are about 2-3" taller than stock. The additional height cause the progressive rate coil spring to uncompress the soft part and could make the truck to feel unstable. It would work good if you got the pressure are right. Get the regular height one and just pump it up when you are carrying extra load.
I also install bypass valve. This basically are just a small ball valve that could isolate or connect both bags. I run it open off road and does not notice any less articulation. Close the valve and it isolate both bag and improve handling quite considerably compared to open.
