The cross over kit for the d60 (currently on sale) says for trucks up to 8" lift. I am running 8" springs (skyjacker) and a 1" zero rate (1.5" forward axle) . Would this kit work for me or am I going to have to look at the "tall truck" kit. This truck is mainly used for medium trails, mud, street and a little of everything, it is not a rock crawler and does not have a huge amount of flex.
