PROCOMP/STOCK SUSPENSION MIX?

I've been battling with local law enforcement and inspection stations, and am finally going to give in.

First off, I bought the truck with it's current setup.

I have a 6.5 Pro Comp lift in the front, and want to drop down to a 2" or 3" lift. I am wondering if I can swap back to stock springs, or leveling kit springs and call it a day. I understand I can go the trial and error route, but I'm hoping that somebody that has this lift can chime in and spread some knowledge first.

I've found stock springs on Craigslist
Ford F350 FRONT SPRINGS
And have also found a leveling kit
FORD SUPERDUTY LEVELING LEAF SPRINGS & SHOCKS

I'm just not sure what I can install with the current setup and still function properly.

I'm not very worried about the rear, I can deal with blocks no problem.

I would think the drop down bracket for the track bar will be an issue and the longer steering arm..but I'm just guessing, with a 2-3 inch lift I believe the factory stuff would work or comes with the leveling kit.

Get out your calculator. In Massachusetts the maximum allowable mechanical lift (as well as what's acceptable in terms of bigger rubber) can be determined by this formula:

Maximum Lift = (Wheelbase x Wheel Track) / 2200

For example, if you did that formula and came up with 2 inches, then a 2-inch lift and a 2-inch increase in tire size is allowable, equaling a total lift of 4 inches over stock.

That is the correct formula, however the number you come up with is maximum total lift and they measure from the bottom of the door to the ground. I'm allowed 5" total.

I would like 2 or 3 inches of suspension lift so I have breathing room when buying tires. I have 6.5" lift now.

Oops. My bad.

That is quite an obnoxious way of looking at it though..
Shame on Massachusetts..

Well, allowing 10" of lift.....they might as well have no law at all. I have considered wheel spacers but I don't think that would get me to 6.5" and even if it did, I still want to lower my truck. I'm getting a 2012 bed and selling my fender flares, so I'll have 34.5" tires and ~7" of lift....it kind of looks silly and I can't get bigger tires, that would be a step in the wrong direction (although it's sweet!)

I want to recoup some MPG by going lower too. I do drive on the highway a lot, the extra height definitely doesn't help.
