Backspacing for TJ on 37s

Aside from finding someone else with the exact same build as you (4.5ā€ lift, long arm geometry, 1.5ā€ front stretch, 3/16ā€ extra steering stop, 4.5ā€ backspacing) except 37ā€ tires, Blaine had already answered your question. Cycle your front suspension and see if you have an extra inch at full lock. Seems much easier than finding the owner of your build’s doppleganger to confirm for you.

I don’t currently have the front axle in the jeep so checking clearance this way is not possible.
