Hello All, I have read many posts and it sounds like the Frestone air lifts are well liked. I am considering a pair for my Chevy 2500HD to bring the rear end hight back to normal. According to what I have read this should be 40-50 Lbs for me. The question I am hoping some of you experts can help me with is should I put in the compressor or just use the manual fill valves. I wonder just how stiff the ride would be unhitched with the bags still inflated. One other question is the single fill versus the dual fill, years ago when I sold shocks it wa illegal to sell with dual fill valves because if one side went out the vehicle would pitch to one side. We still sold the dual valves separately but was wondering if this is a problem or are these air bags so tough there is no need to worry about losing one side. Sorry for the long post but hoping to save a couple hundred buck and not get the compressor.
