I'm going to be putting on 33s when I get my lift. I was told to re-gear to 4:56 which would give me the same ratio as the Rubicon with 31s and 4:11 gears. Then I was warned to upgrade the axles because the D35 wouldn't hold long to serious abuse. The risk is even greater with 35s. IDK for sure, just from what I've been told you'll snap the axles.
