Associated sells a FT shock kit...but the ONLY difference is TiNi shock shafts and different color shock bodies. No need to upgrade the shock IMO...just buy the TiNi shafts and maybe some Trackstar O-rings and you'll be golden. If you are really looking for the best possible shock then maybe try polishing the pistons with a dremel, a polish wheel and some red jewelers rouge (you'll find this wherever dremel products are sold).
