2011 rmk assault - i have not been able to set up the sled for good transfer after playing with the rear track shock i put it back to factory setings and it still felt worst than the first ride at factory setings then i noticed how low the rear of the sled sat, lift up on the bumper and let go the sled drops about 3'' with no weight on the seat or tunnel, press down on the rear bumper and the sle squats another few inches and is very slow to return those few inches...not impressed with only 500 easy miles. when sled was new on garage floor there was no sag and if you sat on the sled and got off within seconds the sled was back to full extension... so should i rebuild/revalve this shock? how about the front track shock? or should i buy fox or other? with this coil over rear shock could i swap shocks with skid in or better to pull the skid?
