does anyone know if you can install old man emu 1.5" springs on xreas shocks? if not why?

 

The answer is basically "no". The shocks are cross linked. So if you now change the stroke of the shock by changing the height, you will affect the opposite corner shock. For instance, if you now raise the front shock up, the rear shock will most likely become more stiff because of the fluid in the xreas system. I think the only thing you could do to add to the xreas system is spacers. In the end though, if you want to go offroad and get a lift, the only option is to rip out the xreas system and replace the shocks all around.
