The upper control arms look to be of very high quality and offer some really nice features. I particularly like the bolt on upper ball joint and greasable bushings. You can tell these are meant for off road use and made to last. Installation was fairly simple just pay attention to the orientation of the different washers. There’s a set of thick washers and a set of thin washers. After installation I had my truck alignment done and the control arms operate very smoothly and with no noise. I used Ams Oil high viscosity lithium complex grease on that bushings and ball joint. I expect these arms will last much longer than the other brand I had on there before which will remain unnamed. My only concern is making sure there’s part’s available in the distant future for replacement bushings and ball joints as I believe they are proprietary(I could be mistaken).
