sagging

Well...ready to pull the trigger on Fox shocks, I installed a v-plow and now the front is sagging. How much preload on the shocks would lift the front and do the shocks come with the adjusting wrench? Thanks in advance.

I just installed a Boss XT snowplow and now the front is sagging from the extra weight. Will Fox shocks help or do I need spring spacers? Thanks in advance.
