Oh Mann,.. I can't believe I haven't seen this thread before..
Back in the day, air shocks were the perfect answer to a week-end warrior at the strip..
Air shock with dual inlets allowed you to pre-load the rear end.
you'd put about 15 - 20 lbs more air in the right shock (like super stock springs)(adjust tire pressures to get and even patch of rubber off both tires ( too low -burns the outsides, too hard, they show more center) .. adjust the pinion snubber,, you got it all..
then lower the pressure for street use, ( if nec,.)
