Yes I have done the Jeep spring on the front of a Track/Kick.  Here is a repost of the results below. ÂÂ
Since Zuwharie I have been collecting coil springs to replace the GV coils on the front of my Kick.  I custom fabbed the IFS suspension to drop 4" and then Installed a pair of GV V-6 front coils with a Jeep Cherokee Coil spacer and a .5" thick ring (Piece of hard plactic / cutting board).  I now have 3 sets of Jeep Coil springs (unknown applications TJ & XJ and  a set of Like new Sammy Coils.  Well chatting on the BBS about Tracker Lifts and having to go cut grass around my dead Kick.  Got me itchin to check out the coils I've been collecting.  The GV coils and coil spacer did not give me the lift I expected so Installing longer coils seem like the next best answer.  If only it were that EASY... ÂÂ

GV Front coils (2wd V-6) compared to stock 4-door Front Coils (Rears are the same size).

Fronts standing upright  to give a better ideia of height differance.  GV coils have one more wrap.
Jeep Tj Coils compared to GV 4-door coils  4.25" longer (But smaller Dia wire with similar # of wraps...  Hmmm

ÂÂ

TJ coils inplace of the GV ones...

Desired 4-dr ride hight / stance.  Ok maybe not quite that high (tires are off of the ground), But close...  [naughty]
But once down off of the Jack stands ...  THe coils compress to the bump stops.  [crying] [crying] [crying]  THe A-Arms act as a leaver requiring a much greater spring rate. ÂÂ
I need a list of coil spring rates for OEM vehicles springs... ÂÂ
I am now running Explorer +2" coils up front and the TJ coils in the back.
You might check into Ford Ranger 4wd coils. ÂÂ

The coils pictured here are stock 4dr, Vitara V-6 2wd 4dr, Ranger 4wd std cab, and Explorer 2wd +2"...
