Shipped fast. Looks to be of good quality. Only thing I didn’t care for is there’s really not a good way to angle the lower ball joints where you can grease them after installation.

I bought the synergy ball joints 2 years ago. The original set was installed with a 3 1/2 inch lift kit. Had 10 miles on them and took it to have Pennsylvania vehicle inspection. It flunked because of bad ball joints. No off roading was done in those 10 miles. Quadratec was great and sent replacement parts immediately. Now 2 years later and only 16 thousand miles of city street driving they are bad again. These are supposed to be heavy duty for off road use. I will never put a set of these in again. I greased them twice a year so it's not a maintenance issue.
