I never really looked closely at u-bolt that closely. Now that I am fully lifted not going to be much of a concern.I just got the Rancho diff skid and It looks like the u-bolt next to the driveshaft may contact the oil pan when flexing. I was only doing a dry fit, but it is really tight while sitting level.
The oil pan is so low on this, almost even with the bottom of the diff. Maybe the 2021 with the different springs on front does let the engine sit lower? I may have to lift just to get the clearance for the diff skid etc.
