Ok building my own long arm system, hope I'm posting in the right forum.

Anyways doing a radius set up, with poly on the axle side and johnny joints on frame side.
I'm putting the frame side mounts on my tcase crossmember , with a removable center to pull trans tcase later. The mounts will be 2in inboard from stock, do they need to be angled or.should they be straight forward?

 

kinda hard to explain, but you can make them straight, as long as the jonny joint is straight. if you want my opinion, do a heim joint setup that is inside a round housing that can we welded to the arm at any angle you want. like I said kinda hard to explain.... I guess i mean kinda like the IRON-Y arm that Iron rock offroad has. I take if your doing a radius arm, the upper and lower will be 2 separate arms that bolt together and probably adjustable?

 

If i were you build a 3 link

 

Yes every thing is Going to be adjustable. This will be driven on road, I have hurd 3 links are hard on caster angles. I'll post more in am sleepy sleepy time.
