Hey Adam, for the hub rotor kit you'd want the DeeMaxx part # DE68YR which you'd need to order a quantity of two of these since you have a tandem axle trailer. This is correct for a 7k axle and has 9/16 inch diameter wheel studs.

Then for a kit that includes everything else you would want the Hydrastar part # HBA16-252-82 which comes with the best actuator as well as all of the rest of the electrical components needed and brake lines. Do you have electric drum brakes currently?
