Hello,
I am the guy Matt was talking about.
an1malch1n, you shold know me from 4x4parts BBS.
I am going insanely whole hog on my '95 XE KC. I am doing a dual axle swap along with coils spring/4 bar linkages. once I get it all built I will convert it to a height adjustable air over coil system.
To be quite honest, if you have some fabrication skills, and the ambition (the really hard part) you can do a leaf spring axle swap for ~$1000. for a coil system aka. the Early Bronco (Frankenfinder) you can look at $1500+
Mine is WAY up there with lots of wacky parts, and lots of fabrication. I am doing it all myself and have searched long and hard to find all of my parts.
Here is my overview so far:
Front D44 $300 From a Jeep Wagoneer so it is 6 bolt to begin with!
Rear Toy 8" $15 I have a few GOOD friends
Jeep TJ linkages $100
Gears 2@$200
Driveshafts 2@$250
Coil Springs (various sources) $250
Steel for Fabrication $200
New brake parts $150
New Shocks $300
2nd t-case $free Good buddy
mini driveshaft for 2nd case $100
So I am at $2315 in just parts.....
But when I finish (another many months and LOTS of money) I will have a truck that can adjust it's height 5" run 35" swampers and ramp ~1000 on a 30 deg ramp.
I personally wouldn't drop the money into the coil overs unless you intend on keeping the IFS forever.
