Original air group can fix you right up. Talk to Ron in the Fla shop.

If you want it right talk to them. They are the ones I went with with my kit and it looks just like the one posted above. If you go the 134A route you need to make sure you put the right amount of freon in the system which will be less than the R-12 amount.
Their chart shows 24 oz of R-12 = 19.22 oz of 134-A. They suggest 70-80% of the recommended charge of R12 in the original system. Th
I also did away with the drier on mine no need for it on 134A system. I used the new accumulator, just more fittings to leak.

I can get the exact amount if you want it and they suggest setting the POA valve to 20 when running 134A.

My system has been working now for over 10 years with no problems. That's 2 3800 mile trips on the HRPT + work.

It sucks not being able to hear! LWB trucks rule, if you don't think so measure your SWB! After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
