The Kodiak Disc Brake Kit # K2R1058D11E is for 9,000-10,000 lb Dexter axles. Assuming you have a standard duty Dexter or Lippert 12,000 lb axle, the correct kit would be the Kodiak Disc Brake Kit - 11" Rotor - 8 on 6.5 - Raw Finish - Leaf Spring - 12K - Dexter/Lippert # K2R1258L12. This kit fits an idler hub assembly like the # 8-214-8UC1. You will need to verify which axles you have in order to make sure this will work, it is not for use with 12K HD axles.
In addition to the disc brake kit, you will also need the HydraStar Hydraulic Brake Line Kit - Tandem Axle - 25' # HS496-252 and a breakaway kit like the Bright Way # 3802308.
Since you already have a brake controller for your electric brakes, the only other thing you will need is an electric over hydraulic brake actuator. I recommend the HydraStar Vented Marine Electric Over Hydraulic Actuator for Disc Brakes - 1,600 psi # HS381-8067.
I have attached some review and installation videos for your reference. I also included a helpful article on adding electric over hydraulic disc brakes chat you can check out.

Are these kits for the 12k axles still available?, I can’t find anything under the part number listed above. I have a big Tex 22gn hd that I’d like to convert to disk brakes. Thank you
