To complement these high quality springs in the 4" system, Zone Offroad adds a dropped pitman arm, front track bar relocation bracket, front and rear bump stop extensions, front sway bar links, front and rear brake line brackets, leaf shims, center pins, u-bolts and a transfer case drop all with easy to follow instructions to guide you along the way.

If you want a larger fullsize spare tire on your jeep, but it won't fit on the stock bracket, here is your solution. This relocation bracket moves the mounting surface out 2 1/4" and up 1.5". This bracket will allow you to install up to a 35" tire. It is designed for the TJ or YJ, but could be used on other rigs with the 5 on 4.5" bolt pattern.
