I am asking if anybody has option, suggestions, or experience with adding air bag lift kit on the rear suspension. I found there are two out there - Ride-Rite & Air-Lift. (RR & AL) They are slightly different -AL mounts with screws directly to frame right infront of the axle, and the RR appears to be added to the side of the frame right above the axle. I say RR appears, because I cannot find instruction manual for them. AL has good infomation online, with detailed instructions available. Somewhere I read for the RR "tailpipe modification/moving" was mentioned, and this seems correct if they are mounted on the inside side of frame - the left tone would be very close to the exhaust. I do like the fact the RR are right on the axle. I am leaning towards the AL, just because it gets away from the heat of the exhaust, even thoug it doesnot put the help right on the axle, and the help still has to go through part of the leafspring. My reason for adding is that I sometimes haul some heavy items, and would rather have the help in the rear for those times. I have a focus wagon, and have had the rear bumper lower by nearly 5 inches, with some loads.
