Shock, Master Cylinder Rebuild Kit, and Pushrod Assembly for Demco DA603  


Hello, I have a Demco DA603 drum brake actuator on my boat trailer. I am looking for a replacement hydraulic cylinder as well as the damper, spring etc. which should be looked at while replacing components. Are you able to point me in the right direction? Thx,

The correct replacement shock is the part # DS12426, the master cylinder repair kit is part # DM24ZR, and for the pushrod assembly part # DM74ZR.
