I have a Ford f-350 super duty lariat diesel truck which I use as shop truck, toy hauler, plow truck and daily driver in winter. Seven years of plowing and im sure just weight of front end like many other trucks the front end is down a bit and this year I updated my plow to a wider flared wing v-plow which is a bit heavier than my straight blade was. I ordered a 2.5" leveling kit from Summit which is basically a spacer that goes on top of coil spring. Has anyone ever installed these? hard to do? better having shop do it? and should you have a realignment done even though it is a solid axle?
