Hey guys. Wondering if anyone has replaced a 136 coupled suspension with the 144 RMK skid and a tunnel extension. I would like more track for off trail and would like to loose the coupled action of the 136 to be able to get up on top of the snow better. Considering putting a 1.75 x 144 challenger if the skid swap will work. Anyone got a used 144 RMK skid to fit an 08 IQ chassis. Would rather get an Assault but its not in the cards right now.
