These rear shock absorbers improved the ride. Let me mention that if installed on a 2009 generation hybrid, you will need to remove the battery vent to properly replace the right rear shock. This was not done on the previous installation (factory?), the top hex was broken and I had to use a saber saw to remove it. Removing the vent takes 4 minutes. Do this instead of trying to inflict a new shock in a faster and more terrifying way.
