Impala 18" Wheel Rear Struts
The 2008 Impala has several different configurations for Rear Struts - depending on police/taxi, wheel size, etc. I finally was able to distill down the bewildering selections for my Impala SS, and AutoAnything had the correct set. Installation is within the average weekend mechanic's ability and tool set (15MM and 21MM Sockets) and the willingness to crawl in and out of your trunk a few times. The KYB shocks improved my car's ride and handling immediately.
