I want to buy an electric over hydraulic brake controller kit. Triple axle disc brake trailer. what is the difference between CAR-HBA 16-2 and the HBA 16-252-82 ? I will be towing with a 2016 Ram 2500.

Hey Luke! Great question. The difference between the two is the length of the main brake line. The Hydrastar Electric Over Hydraulic Actuator Kit for Disc Brakes # HBA16-252-82 comes with a 25' long line and the # CAR-HBA16-2 has a 15' long line. The rest of the parts are the same between the two. You will also need the Hydraulic Line Kit, 3rd Axle # 9579-01 since you have a triple axle trailer.

What kind of trailer do you have?

Hey Luke, did the Hydrastar Electric Over Hydraulic Actuator Kit with the 25' line work well for your triple axle trailer? I'm curious to know if it met your needs, as it could help others with similar setups.
