The 9294 and my kit have a max lift 1/4" lower than the max lift I measured
on the oem set up from the bogey pivots to the road. 1/4" less lift at the
bogeys will prevent over extension of the shocks since 1/4" at the bogeys
will be an even greater reduction of extension at the shocks.
The cone end on the 9294 is similar in design to the oem with the cone
being a separate removable piece. The bag is only permanently attached to
the plate end with the fill port.
