I run them and really find them a nice improvement over stock. Aside from the PITA install...they are an affordable upgrade and really help with the rear end when under throttle. Not being a road or drag racer I was not concearned with the "best of the best" mentality...there are definatly better pcs available, but for me these met my needs perfectly. I would recommend getting a fresh set of axle bushings from the local parts store prior to the install...you'll be glad you did when you get the uppers off and see their condition. You can also take a look at torque box reinforcments as an option if your into drag racing and or launching on sticky tires.
