Timbrens, air bags or air hitch

I have airbags with a homemade expansion tank, air adjust Rancho shocks and in-cab control for both. I could feel the bags unloaded, slightly, so I added the exp. tank and that made them absolutely undetectable. The adjustable shocks make every bit as much improvement as the bags... They compliment each other very well. I adjust the bags for the load and the road condition and with the shocks I have full control of the sharpness and oscillation. I also cut the ends off the bottom overloads which was the first thing I did. I spent a LOT of time on my suspension but I don't know if my recipe will work for every truck. I made one change at a time til I got mine perfect. You might need to experiment a little cuz every truck and load is different. Craig
