Hello all. A previous owner installed a 2" suspension lift. The t case drop was 1.5 inches. I thought it looked a bit much. After looking around here and digging a little. I'm pretty sure the drop kit is for a four inch lift. I removed the spacers and replaced with 3/4 inch of flat washers. It feels smoother shifting. The rear driveline is at 10° now. I ran at 70 for 30 miles with no vibration at anytime. A SYE is in the future. But for the time being will this set up cause any problems?
