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?
