Drop pitman arm?

I'm not sure where I should post this but I have a YJ with 5 inch suspension lift and 35s. The steering is all over the place. I can hold the steering wheel strait but it will still dart all over the road. all ball joints and TREs are new. From the looks of the pitman arm i think I need a drop pitman arm. Do you guys suggest this or do you have any other ideas?

You need the drop pitman arm , install it and have the front end aligned by a competent shop. Be sure and note the caster angle if it is out of spec add angled shims under the spring perches to correct the caster angle.

The goal is to get the drag link parallel to the axle, which takes more than a pitman arm to accomplish with that lift height.

SOUNDS LIKE IT DRIVES PERFECT ! ....just kidding .
5 inch springs ? no angle shims ? sounds like you just recently lifted it.
The darting all over the road you describe sounds more like the caster is out of wack than a pitman arm issue , get the alignment angles checked and shim as needed .
With 5 inches lift leaf springs I would ditch the track bar [not necessary with leaf springs] and install a drop pitman arm and maybe do a tie rod end flip to the top of the knuckles to level the drag link more [and lift the tie rod up a couple inches] otherwise you are going to have bump steer issues.

Edit: If you keep the track bar it should be parallel with the drag link to prevent bump steer, so if you install a drop pitman you will probably also have to drop the track bar frame mounting point and maybe raise the track bar axle mounting point in order to get them parallel as possible to minimize any bump steer [toss the track bar].

Yes you should have a drop pitman arm, but with your lift I'd be looking at over the knuckle or high steer. I have the same size lift and went to Ruff Stuff Chevy 1 ton Y link and flipped the tie rod over the knuckle. Much better manners on road and off. If you're interested I have a new RE drop pitman I'm selling 1/2 price of new.
