Yes, the HydraStar Disc Brake Kit w/ Actuator for Triple Axle Trailers - 13" Hub/Rotor - 8 on 6-1/2 - 7K
Item # HSE7K-TR1 is a complete kit for swapping the brake components. Since the current bearing grease has to be removed during instillation the new bearing need to be packed. I recommend Prime Guard Wheel Bearing Hi-Temp Red Grease Item # L11380.

It is also recommended to add a 40 Amp In-Line Circuit Breaker - Perpendicular Mount Bracket Item # 9510 to protect your vehicle wiring when connecting the actuator. Since the wires are outside and susceptible to moisture I also recommend Deka Heat Shrink Butt Connector - 12-10 Gauge - Nylon Insulation - Yellow - Qty 5 Item # DW05745-5 when wiring the actuator to the factory 7 pole on the trailer. A lot of times they use crimp connectors instead of wire nuts and the crimp connectors often cannot be reused because they get damaged during removal.

The install may require the wires from the actuator to be extended. You need extensions that are at least a 12 gauge wire. I recommend about 20 ft of Jacketed 2 Wire (Brake Wire) - 12 Gauge - per Foot Item # 12-2-1. Cut the 20 ft in half and you have 4 wires that are 10 ft long. You want to make sure, after connecting the extensions to the actuator wires you mark the ends, so when you feed them above the nose panel of the trailer to the wiring box on the bottom side of your your king pin, you know which wire is connected to what color wire from the actuator.

If you have a 2007-2008 Ford, a 2007-2017 Ram, or a 2007-2017 Chevy/GMC with a factory brake controller you also need HydraStar Electric Over Hydraulic Actuator Adapter Module for Ford and Chevy Brake Controllers Item # HBA-CAM. This insures that the actuator works properly with the factory brake controller signal output.
