Love these upper control arms they look amazing and fit perfectly, durability is great like all FLM products. I would rate these five stars but I have to say, they are very hard and frustrating to adjust properly with no hex on the adjustment screw or even a simple hole so a small Allen key would fit to hold the screw in place while you tighten the jam nuts you are forced to use the two jam nuts tightened together to spin the screw for adjustment as well and when you go to spin them back the opposite way to lock in on your adjustment you always end up spinning the adjustment screw and mess up your adjustment. Something simple to hold the screw would make these perfect.
