Replacement Rotor for a 2020 Keystone Montana 3121RL
Question:
I have a 2020 Keystone Montana 3121RL with the Legacy Package. Im in need of replacement disc brake pads and 1 rotor. Brake pads ended up with uneven wear so the brake pad indicators gouged the rotor. Looking at the brake pads they look like Kodiak pads but not sure of what type of rotor I have for my rig. The serial number for my Dexter Axle is 132190011. Going to Dexter Im having trouble figuring out if I need a hub and rotor or can just get the rotor. Thanks

If all you damaged was the rotor then you can just replace it with the Kodiak 13" Rotor item # KR1389D.
I didn't get anywhere either with that serial number. However, it looks like your 2020 Keystone Montana 3121RL uses a inner bearing item # 25580 and an outer bearing item # 14125A. The Kodiak 13" Hub and Rotor item # KRH1378D you were looking at is exactly what you need to replace your gouged one if you want to swap out both the hub and rotor.
For replacement brake pads you'll want the Kodiak Ceramic Brake Pads item # K250CP-SS. I recommend replacing all of your brake pads. This set will do one axles worth of brakes.
