Are The Disc Brakes On a 5 on 4-1/2" a Different Diameter Than On a 6 on 5-1/2" Disc Brake

Question:

Wanting to change my 5 on 4-1/2" hubs to 6 on 5-1/2". Are they the same diameter? I have disc brakes on my trailer. Want to be able to go from my 15 rim to a 16 rim that you sell .....thanks

Your current rotors with the 5 on 4-1/2" hubs are likely going to be 10" rotors like the Disc Brake Kit # K2R35D. When you move up to the 6 on 5-1/2" hubs you will likely be moving up to a 12" rotor like the Disc Brake Kit # K2HR526D. If you can provide me some more information about the axle(manufacturer, serial number, disc brake kit) on your trailer I will be able to see if we have a hub that will fit with the larger 16" wheel you are wanting to go to.
