New Generation II  Gas Shocks  from Dynamic Auto Design.  

These are authentic Dynamic Auto Design. D.A.D sport gas shocks - designed to replace your stock shocks and give your car better ride and handling qualities. A sophisticated multi-stage compression valve system enables the shock to respond instantly under aggressive handling conditions, maintaining vehicle control and providing maximum grip and traction. Internal 30mm cylinder for more room and less heat; reduced friction and prolonged piston life. Pressurized nitrogen gas system to pressurize the oil and provide superior performance.

Multi-lip piston rod seal with check valve system - protects against contaminants and minimizes foaming (caused by the mix of oil and gas inside the shock), providing a reliable high performance system. Hardened chrome, micro polished piston rod manufactured under strict conditions to guarantee a perfect surface, without any imperfections, to provide an extra long seal life and smooth operation. Specially compounded oil for minimal viscosity changes under extremely temperature variance. Multistage valve piston system to insure the best damping control even under special driving conditions.
