The 512 Series was the first aftermarket shock made specifically for Utility ATV’s. They have undergone extensive R&D to provide the finest possible suspension for your workhorse vehicle. We use improved spring rates for heavier load stability and handling over rough terrain as well as increased length for more travel and ground clearance. The 512 Series comes with an adjustable spring preload to accommodate different loads (i.e. mounting a plow or carrying a hay bale). Also included is our Shock “Sox” to help keep dirt and mud out of the spring and to keep the adjusters clean.
