I will have to disagree on respect to OME shocks and springs on the rear. I was running OME 891 springs and N86 shocks for years before redesigning the suspension last year. I still run the OME 891 springs but with Bilstein shocks. The springs have given me the best ride for what I do and they have held up better than any other spring set I've had. In other words they have not sagged a bit.......
I know many who are very happy with the OME lift.....
