Please forgive my ignorance, if this is not the correct place for this tread, sorry. Doing solid axle swap, wondering what is the reason for the different versions of pitman arms, (flat, 3/4, and regular drop.) Best I can figure is it depends of amount of lift. Most pics I see have stanard pitman arm. Thanks for any info.

 

I'm by far a SAS expert, but if I'm not mistaken, the reason people swap to the flat pitman arm is because under high flex situation, the spring can actually come in contact with the drop-style pitman arm

 

bleeder, I didn't know you were a SAS expert????!

 

thats great, but yeah i think supers right

 

90% true- the whole idea when u do a sas is to move the front axle as far forward as possible. usually it involves relocating the steering box as far farward as possible to clear the tie rod. If u look at how the steering box is mounted on the 86 to 95 frames it is kicked back at the bottom. putting a flat pitman arm on might cause either the tie rod nut and or the pitman arm to hit the frame. When u move the box forward usually u have to make it more perpendicular with the frame, hence the need for the flat pitman arm. U don't need it if ur running ur box in the stock location. u just have to make sure the tie rod clears the pitman arm and put some bump stops on to keep the uptravel down a little.

 

Thats great info, and makes sense. Leveling out the steering box, and using flat arm seems like it be the strongest combo. Thank's everyone for your replies! BTW, I'm working on an 89 toyota pu SWB, using an 84 4runner front axle. Looking at the addicted to offroad SAS "classic" front and rear lift kits.
