yes,,but why would you want to? if you have pioneer re-valve(under 100$ including shipping,7 to 10 day turn around) the rear shock,you will be happy with it.Is it possible to swap out a mono shock from a 07 apex er and install a dual shock from a 07 rtx
get it revalved,it'ds like a different skid.I am also very interested in this. If you do it, PLEASE take pictures. I am just not happy with the mono in bumps. I guess I don't ride like the average bear.... Not crazy... But I find a smooth trail to be very boring.
