Pitman Arm options
I am looking at options to swap out a pitman arm on my 4x4x2 box to gain a little distance from the drag link and lower link at compression. - I don't know what or if I have options but would love to find a drag link that is slightly shorter, even 1/4 or less. I can take some measurements tonight if need be. Thanks!

Re: Pitman Arm options
Pictures would be helpful. So you say there is a potential interference between the pitman arm and the Tie-rod at compression? Can you clock your pitman arm to help?

Re: Pitman Arm options
I was just thinking if you could clock it one tooth, that may be just enough to gain the clearance you need. But I do think that some of them you cannot clock because they have alignment splines. However, it is all in how the wheels are turned. A turn in any direction will help open up that gap.
How much of an interference is it? Just a scrape? I wouldn't worry about it. Even if it's a hard rub, I wouldn't be concerned. If it's trying to bend one or the other, then you could grind flat spots at those sections and repaint. I doubt you'd grind away enough to worry about strength issues.
Perhaps there is a slightly shorter pitman arm out there as well? Is that a drop arm? Maybe a flat one would be better?
Do you think at full compression that the tie-rod DOM will hit the joint at the pitman arm?

Re: Pitman Arm options
The manual steering arms are slightly shorter but also less beefy.

Re: Pitman Arm options
Astro arms are also short and completely flat.
