There are a few differences to consider between the Kodiak Disc Brake Kit - 13" Rotor - 8 on 6-1/2 - E-Coat - 9/16" Bolts - 8K Dexter Disc Kit # K2R89DDE and the Kodiak Disc Brake Kit - 13" Rotor - 8 on 6-1/2 - Dacromet - 1/2" Bolts - 7,000 lbs # K2R712DAC. First off, the # K2R89DDE comes with a 9/16" wheel bolt diameter while the # K2R712DAC comes with a 1/2" wheel bolt diameter. Secondly, the weight capacity of the # K2R89DDE is 8,000 pounds while the # K2R712DAC has 7,000 pounds of weight capacity. Lastly, the # K2R89DDE has an outer e-coating (which gives it the black color) while the # K2R712DAC does not have that coating.
With considering these differences and research I conducted on your tde46890 rotors, it looks like you need the # K2R712DAC. That should work fine with your setup.
