I fitted these to the front of my 2002 Ford Crown Victoria LX SPORT. Wow! Harder, but not too hard. Before putting them on I tried to fold them by hand and couldn't. If you buy a shock absorber and it can be folded by hand, those shock absorbers are useless. Worn shock absorbers can be folded in manually. These are the best shock absorbers. I added her photo to my Vika crown. Yes, they are built into the main coil spring. Roll up the spool in your LOL spool.
