Stiff, controllable ride. Good ground contact and OK ride quality. They handle the front weight well.However, the design of having to use a key on the top of the center of the stud to stop rotation while you tighten the top nut is ridiculous. The old shocks had a nut integrated on the bottom bushing portion that you could secure to move the nut on top. This Bilstein design is such a huge flaw. Why would you design something like this that you can not use a socket to tighten?With the clearances on my vehicle, I was able to contort a tool on top, and then take a wrench to turn the nut 1/4 to 1/2 a turn at a time, and the studs are pretty long. This also raises the question on to how do I verify I am using the correct torque on the fastener? Most people will not be able to with this design.This alone is enough to never have me go through this again to install this shock. When it is time to remove and replace, I will probably end up just cutting them out and replacing with a different brand.
