To get the most out of your new suspension setup, it's recommended that you replace all parts that are known to fail. Not only will this make your new setup more effective, it will provide a better ride, proper tire position, and make all of your parts last longer. One often overlooked piece is the upper shock mount. This is the top mount for your shocks and provides a solid platform for your suspension. If worn, the bearings within this mount will make noise, there will be slop from worn rubber, and it can shorten the life of your shocks.
