4 Link Rear Setup Help

[Dbteak]

I would like some feedback on my 4 link set up. I have never set one up before so I have no real world experience with the numbers the spreadsheet spits out. From what I read the set up should work except for the uppers are not at a minimum of 45 degrees. Not sure that could be achieved without having 24" links. The axle cycles with no binding and has about 3/8 rear steer and the pinon angle increases as it droops. I took some screenshots of the calculator to look at. Not sure what other information would be needed to help with the set up. Doug

That would be a very neutral set up, it will work just fine and be stable. I would lower the frame mount on the uppers a little, I prefer a bit more AS, but would have no issues with what you have. Please post a pic of the graph, converting all of those numbers to an image makes my head hurt. The image would help a lot with any final critiques, but I doubt there are any.

Here is the plot. Hope it helps.

Here are the numbers lowering the upper frame links 1 inch. Thanks in advance for all the help and any advise.

With the constraints of a bronco that's about as good as you can get. I like the slight boost in anti squat of the second one. It's not enough to make a noticeable negative effects but will make a huge difference when your tires are hunting traction.
