Hm, under 5,000 to build a jeep better than a Rubicon...
4 35" MT's $900
15" steelies $200
Teraflex springs for 2.5" shocks rear TB bracket new rear sway links $500
quick disconnecting front swaybar $100
rear ARB locker $800
Rubicon take off Front D44 $1500
5.13 gears 1500 including labor.
I'm a little over budget, but this setup will kick the living sh*t out of a stock Rubicon. Instead of a front D44, you could install some chromo shafts and gusset the C's on the 30. It'll hold. Now you're at 5,000 budget AND better than a Rubicon.
2 Rubicon decal stickers $30.
Now it's built
