I'm pretty sure they changed the design. I recently was gifted a gamechanger kit for a gladiator to harvest the front end components. Not only are the front upper control arms straight, but the rear trackbar for the gladiator was straight as well. Both new designs have a bend in them now.I'm curious as to what kit you have? I looked at mine last night, and my upper control arms don't have a bend to them.
mine are straight also. the stock arms are oval shaped near the frame providing more clearance.I called and asked why the difference. They said they had issues with them rubbing on the frame at full flex on the diesels so they changed them.
