Front 3-Link Setup

[RuffedUpXJ]

I have had horrible short arms on my XJ for 5 years or so now and I am in the process of swapping all of my aftermarket parts over to a nice, clean and straight XJ. I have looked into 3-links before and understand the majority of it. Most people say 5-7in of separation at the frame and 8-10 at the axle and just make whatever you can fit. So that's all good and I can definitely make that happen but with the 3-Link calculator there are some number I don't understand completely and also I don't know what to shoot for.

Have any of you figured these numbers out?

Anti-squat? Shoot for 100% since there is that line on the graph?

Roll axis angle? I know on the rear it will steer the rig one way or the other but the front end most people say it's not as big of a deal. Shoot for 0 degrees I assume.

Roll height center? I know that has to do with track bar placement and doesn't seem to effect anything else. So not sure of a number to shoot for there.

Here is a rough version of what I think I can do on the front end of the XJ.



Also there is always a big debate on what joints to run and where to run them. I think right now I am doing 3/4 hiems on the upper link and I have some 1.25" hiems for the lower but not sure if rubber bushings would last. The XJ does a lot of road because I drive it to and from but also, tow the boat and other trailers around.
