Expert Reply:

The Kodiak Disc Brake Kit # K2HR35D-8 is designed to fit a #84 Spindle # TRU64FR that is typically found on 3,500lb axles. This kit use 8" rotors allowing you to fit a Kenda 205/65-10 Bias Trailer Tire with 10" Galvanized Wheel # AM3H490. You will need either the EZ Lube # DBRKHW35EZ or Standard # DBRKHW35 Bearing Kit to mount the included hubs on your spindle.

You will also need to upgrade your surge coupler from drum to Disc # DM62VR. If you can tell me exactly what coupler you have I can let you know if there is a replacement master cylinder that will convert it to disc brakes.
