2"? If Rockslut uses front Waggy springs in front and 2.5" ranchos in back, I'm guessing stockers would be like 2" lift spings on a YJ.

yup 1.5 to 2 inches depending on your rigs weight and the springs yah get.

Hey sweet rig! :flipoff2:

Yeah the are good for 2" or less. Depending on the spring count (7 leaf, 6 leaf, yada yada) I would only go with the 6 or 7 leaf packs. I have 7 leafs on the front now.
