Bought the Airlift kit for the front springs on the Bounder. Started working on it today. They claim one hour each side.....@&$:;( Took me 6 hours just to get the OE dry rotted/spring formed bags out!...
I warmed them up in water, squeezed as much air out as possible. I had to make a fitting for a plug to stop them from re-inflating. rolled them up as much as possible. good luck, not a fun job, but they did go in. An hour or so on each side. the real fun is getting the fiber washers to stay on the top and bottom.
