quick question

I am looking at getting a 3 or 4 inch suspension lift on my 97 wrangler. And some lift kits have a "Drop Pitman Arm". Do I really need it? and what does it do?
thanks guys

A DPA is needed when you have an adjustable trac-bar and also utilize a drop trac-bar bracket on the frame side. For perfect steering geometry you want your Trac-bar and Drag Link to be parallel to each other. So if you drop the trac-bar you also have to drop the drag link as to not max out the tie rod ends. There's a picture of the steering setup on TJ here some where, I'll see if I can find it.

Basically for a 3 inch lift you do NOT need a DPA.



Here's the diagram I was describing. You can see the Pitman Arm is what connects the steering components to the steering box itself.

You won't need a DPA until you reach about 6" of lift on a TJ.

And you should be thankful. They are a pain to change. I broke 3 pullers, and finally had to cut almost through it in 2 spots to remove it. Not fun!

If you have to ask what it is or what it does, you don't need it, and you will need help to install it!

Even at 4", some lifts MIGHT require it, but if you do an adj track bar w/o any kind of drop bracket, chances are you won't.

If you do a 4" lift, install it all, except the DPA, then only install it if you find you need it.

Yes, a tummy tuck will affect driveline angles (raises trans and t-case) but will not affect track bar and steering (does not change distance from axles to frame).

Depends on your method. Use the puller to put tension on the pitman arm. Once you get it tight use a hammer to free the pitman arm. You should hit the pitman arm directly. Usually takes a couple turns of the wrench to tighten the puller again and hitting it with the hammer before it pops free. I learned this the hard way thinking the puller was supposed to do all the work. Snapped one myself.

Nice Andy I was just going to say the same thing about tightening the puller and the apply the appropriate whack with a hammer right on the side of the pitman arm. Works every time.

That's how I broke the second one!
