ZJ pitman arm on XJ?

I´m thinking about using a ZJ pitman arm on my XJ (7.5" lift, Currie HD steering), because I heard it´s about an inch longer. And longer isn´t a bad thing, right?

To avoid bump steer I would have to lower the trackbar mount about an inch - did I get it right?

What else is involved in this swap?

Thanks!

I am running one. It is not longer but lower which is a better thing. It lowers the drag link 3/4" so you need to either raise the axle end of the trackbar or lower the frame end 3/4" as well.

OK,
I´ve just read it on your site, seems pretty simple to raise the trackbar on the axle - thanks!
