AST 4200 Series
The 4200 Series shocks use AST’s Twin Piston Dual Adjust (TPDA) technology. Similar non adjustable versions have been found in the highest forms of racing. TPDA builds on this technology to allow for 2 adjustment knobs to be mounted on the shock body (no tools required). Quick rebound and compression changes can be made in the pits in seconds. 4200s are fully customizable and rebuildable.
