No. If you’re using caster correction bushings or caster plates these will move your tie rod closer to your radius arms and may cause interference.
However, with these brackets they lower the rear of the arm, which actually moves the arm away from your tire rod end. Due to the fact that this version of the bracket pushes the tires forward he notes that it may cause interference with the pan hard rod which may require some grinding.
I never said anything about tire size affecting caster.
Sorry, I must have misunderstood your comment about 35's
These Eim Keith brackets are basically what I was thinking of trying to fabricate myself.... If I tried to make these they certainly would not have looked as good. I don't know how I missed them as a product. I had no idea they were on the market. They sound like a good set up if your not using the a 80 as a rock crawler. I just did some icon caster bushings to try them out and because having a press I could do them on my own and they were meant to be a cheap fix for the next year. I wish I would have just ordered these instead. So for smaller lifts the only advantage that I can see with delta vs arms is retaining the original ground clearance where the arm meets the frame and (if you need them) you get new oem bushings pre-installed.
