I do have a full replacement for you but we do not offer replacement parts for the Reliable ACT-7.5K Brake Actuator unfortunately. For a full replacement, the best option we have for you is the Swing-Away Actuator w/ Electric Lockout part # T4839100 for disc brakes or the Swing-Away Actuator w/ Manual Lockout part # T4839000 for drum brakes. These actuators have the same 2" hitch ball compatibility and 7,500 capacity as the Reliable ACT-7.5K brake actuator that you have now. If yours did not have the swing-away feature then this is a great time to add this.

Hi Conner. I need the full replacement for Reliable ACT-7.5K Brake Actuator. I already have the swing away tongue installed. I did not see the product on your website. Is that still available to purchase?
