you have two ways of attacking it, either start from the beginning and go with 30k front dif,5 rear 5mm front RC shims. blue sway bars. or go with the "new" style which is is pin the shaft 10/5k dif fluids. 2mm RC shims, RCshox garolite slippers, 2 stage pistons and saddlepacks. the truck is still evolving but at a fast pace! when the FT version comes out its going to be a much better truck out of the box!
