Here are the parts I bought seprate over time for my excursion that I will be doing soon. I will be doing the "B" rear spring mod that every one recommends
F250 rear leaf springs Craigslist: $75
F550 "X" code front leaf springs ebay: $175 shipped
Welded 4" rear blocks powder coated ebay: $65 shipped
3" mini spring pack for the front ebay: $120 shipped
Custom adjustable front track bar ebay: $120 shipped
(4) blistien shocks: $300+- shipped
Longer rear U-bolts: $49 shipped
That's a 4" lift for around $900-$1,000. It high enough to run 35" tires.
Are you happy with your lift on the Excursion? Would you change anything I'm looking to do something like this to mine.
