UPDATE:
The Icon Shocks are good, and I have now done 100.00km on the (rebuild after 80k), one of the the Slinky Springs broke after 60.000km. The kit supplier has been horrible to work with over 6-month delay, tons of deadlines missed, and a lot of BS told. No warranty for the springs either. It was not that easy to get service kits for the icons, and given the service and warranty from DMR has been shocking, I next time rather go King, Fox 2.5 RR or the likes instead of Icon.
After a few months of waiting and many supplier deadlines missed, I finally received the Slinky Long Travel Stage 4 Heavy Duty Suspension Kit, which includes Custom heavy Duty Coils and custom manufactured and valved adjustable remote reservoir shocks by Icon Suspension USA.
