I have Icon stage 2 and was very impressed with the ride quality both on and off road. It's been 2 year now and 3 of the 4 shocks started leaking. I also had issues with the cheap rubber bushing falling apart. 2 other friends with Icons have had issues as well. One has had the top stem pullout of the shock cap twice. Both have experienced leaking as well.
I have since switched to Slee shocks which are made by a local to me shock builder, ADS. I have run their shocks before, on my rock buggy with numerous top 20 finishs at KOH. Never had any quality issues with them. Time will tell how they do my my LX.
