We do have all the parts you will need but they are not available as a single kit. First you will need to verify your hub bearings and grease seal to ensure you have the standard 3,500LB sizes. The Inner Bearing # L68149(1.378" ID), Outer Bearing # L44649(1.063" ID) and Grease Seal # 58846(1.719" ID) are the common sizes used on 3,500lb axles and the hubs. We have the Hub/Drum # AKHD-545-35-G-EZ-K for EZ Lube spindles or the Hub/Drum # AKHD-545-35-G-K for standard spindles. Both hubs are galvanized coated to resist corrosion from road salt since you will most likely be driving in the winter. You will need to order a pair to complete your axle. They include new bearings, races, seals and lug nuts to install on your spindle. I recommend using the Electric Trailer Brake Kit # AKEBRK-35-SA as these are self-adjusting which will eliminate manually adjusting as they wear and provide better braking.

For the electrical you will need a 7-Way # HM20048 and Junction Box # 38656 to add a 7-way on your trailer. If you need a 7-way or brake controller for your vehicle, please let me know what you will be towing the trailer with. You will also need a Breakaway Kit # 3802308 which will activate you trailer brakes in the event of a disconnect while driving. Finally you will need Wire # 10-1-1 which we sell by the foot to run to both the brake assemblies.
