. Installed on a 2001 Cadillac Deville (which they were meant to fit). They fit, but the OEM has a "knob" on the base that fits into the control arm so they index properly. These aftermarkets don't have this knob, and the gap in the arm underneath where they install is wide and deep enough that contact with the car is minimized to the point that I don't feel comfortable installing it the way it does is. I ended up cutting out the rubber button/grommet from the old parts to fill in those gaps prior to installation. Everything seems fine. 3 stars because this was not reflected in the description or on the Energy Suspension website. The part is designed to be a one-stop solution, but it really isn't.
