Shock Rods

Piston Rods used for shock absorbers, strut rods and gas springs need a hard chromium plated surface to provide excellent wear and corrosion resistance as well as a low coefficient of friction. Without this coating the service life for these components would be very short. The components are placed on vehicles at locations where they are subject to considerable environmental impacts such as corrosive salt-water solutions from de-icing of road surfaces and from stones hitting against them from the road.
