To those of you that have run the Airlift 1000 (in coil) airbags in your jeeps...Have you found that they have/do hold up well? Air leaks/tears/abrasion from coil rub/etc? Do they hold air reliably enough to NOT have to install an automated system to maintain pressures? After exhausting all existing off the shelf coil springs(in terms of finding a heavy enough spring rate for the rear of my VERY heavy LJ), I'm installing a set of Airlift bags in my rear coils(which are OME 4" with 235lbs/in) and hoping to just fill up the bags with my compressor and check the pressure once a week or so. Eventually, I will plumb the bags into a tank with a regulator and use my OBA compressor to automatically maintain set pressures...but I'd like to put that off for a while if possible. Any other tips or advice for using/installing these bags? Thanks.
