On the road or on the trail, ADS coil over shocks are built to last a lifetime.
Coil over, which is short for coil spring over shock, is simply a shock with a coil spring incorporated over the body. ADS coil over shocks are built using the some of the strongest materials available. For example, all ADS coil over's use a 7075 aluminum shock piston, which is more than twice as strong as 6061, to resist cracking and warping from the extreme heat generated by off road use. On ADS' 3" and larger diameter coil over’s the shaft material is upgraded to induction hardened shafting with a hard chrome finish due to the extreme demands placed upon larger diameter shocks.
A shock absorber works by converting kinetic energy into heat which is absorbed, and eventually dissipated by the shock fluid. In on road applications the shock shaft moves very little and as a result the heat created by the movement is minimal. In off road applications the shaft moves a greater distance and often at a greater rate. In these conditions the shock is generating a lot of kinetic energy and therefore a lot of heat. The strength of the material used to build the shock will dictate the longevity of the shock. By using the strongest materials and the finest fluids, ADS shocks are designed to serve customers for a very long time.
