you dont need a DPA - here's why -
first read here: http://www.opiebennett.com/Steering.htm (i ran 5.5" front end on stock steering, still have 5.5" front end lift, still have stock pitman arm...)
second:
a DPA will throw your trackbar and drag link out of parallel allignment - causing mad bumpsteer with only 2" of lift....
third:
if you still think you need one - search around a little in mod tech...
(just trying to save you a little cash - not tell you how to build your rig)
Explorer ProComp part # YJ400 pitman arm is the same drop as a stock ZJ arm (3/4" more drop than a stock XJ arm). Perfect to correct draglink/trackbar alignment with a Rubicon Express HD trackbar and bracket.
