Too bad those springs are unavailable.. Twelve years ago they were Aussie made, a lot better quality
I too have had some horrific experiences with MAF. I don't do business with them any more. OME springs are the best I have ever had on anything, period. Twelve years and 170k miles on the same set. They will handle virtually any load and ride much smoother than stock under any condition. They may not be the highest lift or whatever, but they cannot be beat for quality, ride, load capacity or longevity. I did a SOA conversion a few years back with these same springs. I modified the rear mounts to keep the springs as close to the frame as possible. It worked out very well and the rig has super long legs now, I can drive it like it's my CR500, it just absorbs whatever I throw at it.
