I had to search several stores in Los Angeles before I found one willing to install them. In West Los Angeles, try to fix your car now. Getting dressed took two hours. These spring clips appear to be of good design and appear to be strong and durable. I used them to raise my 2009 Honda Odyssey about 2-1/2 inches (recommended maximum). The car's ride is stiffer, which I like. It no longer sags in deep driveways. This is a huge improvement and I highly recommend it.
