I'm finally going to fix my caster with some lower control arms...my question is what are most people setting there arms at with a 3.5" lift.. eye to eye measurement ??

 

Most people start at 23in eye to eye, and adjust from there if needed. Which is about 3/8in longer than stock.

 

x2 with 23" eye to eye...teraflex suggests adjusting them at different lengths...but just my personal experience, I found it never handled well set to different lengths and re-adjusted them to equal lengths (enough for me to have +5.5 castor)

 

x2, i dont have a long are but best i could get my caster was 5.5 and it drives like stock no lights dings buzzes at any speed even on off on ramps

 

Mine appear to be just a tad (1/16-3/16) over 23", but the drivers side is about 1/8" longer. It is very difficult to get an accurate measurement with them installed at dusk. I will try measuring more accurately this weekend. 23" is certainly a good starting point.
