For recreational use CO2 is fine. We just set the regulator to the desired pressure and use a normal air chuck.
Most of our air bumps are only running about 50 to 100 PSI.
Get rid of the factory spring plate and use a flat one. Land the bump on the plate with the u bolts cut off at the top of the nuts. I just did a set on a blazer with 10" to 12" of vertical travel and they hit very well and don't get interference from the nuts.
