Expert Reply:

We don't carry a kit compatible with the 4400 lb axles. We have 3500 lb assemblies that will fit your axles, but that will lower your capacity and will require new wheels because they are only compatible with 5 on 4-1/2 bolt pattern.

If you choose to go this route, I recommend the Kodiak Disc Brake Kit - 10" Hub/Rotor - 5 on 4-1/2 - Dacromet and Stainless - 3,500 lbs # K2HR35DS. The brake flange may require customized mounting because you have the 4400 lb axle. We will also need an electric over hydraulic actuator, and I recommend the HydraStar Electric Over Hydraulic Actuator for Disc Brakes - 1,600 psi, # HBA16. This will convert the electric signal to a hydraulic master cylinder system. We will then need the brake line kit and I recommend the HydraStar Hydraulic Brake Line Kit - Tandem Axle - 25' Long, 1/4" Main Line, # HS496-252.

Then we will just need to get you wheels to fit your new bolt pattern.
