The items in your cart are:

Hub and Drum Assembly # 84557UC3-EZ
Idler Hub Assembly # AKIHUB-555-35-EZ-K
Right Hand Brake Assembly # AKEBRK-35R
Left Hand Brake Assembly # AKEBRK-35L

All of those will fit the axle you referenced. However, you won't need both the Hub and Drum Assembly and the Idler Hub. You need one or the other. If you're adding brakes to the trailer you'll need the hub and drum. Unless you have multiple axles and you're only adding brakes to one axle.

If you don't already have them you'll also need a breakaway kit, wiring, and an electric brake controller.

You're going to need to wire the trailer to power the brakes. This will require to have a 7-way connector if it doesn't already have one, like # HS381-9000. It's attached to a junction box to make wiring everything easier. You'll also need ring terminals, # 44-5310A, to connect the wiring. Then use about 20 feet of 10 gauge wire # 10-1-1, which is sold by the foot, to run the wire from the junction box to the trailer's brakes.

The trailer will require a breakaway kit. The Hopkins Engager # 20099 is our most popular kit. The breakaway kit engages the trailer's brakes in the event the trailer is separated from your tow vehicle.

In order to control the trailer's brakes you must have an electric brake controller in your tow vehicle. If you don't already have one I suggest the Prodigy P3 # 90195 because of how reliable and easy to use it is. Its one of our top brake controllers. If you tell me the year, make, and model of your tow vehicle I'll see if we have a custom harness to install the controller. And also anything else that may be necessary.

I've linked some videos on the products I've recommended for you to take a look at.
