Sportsman 400L Rear Brake Rotor

Polaris wont sell you just the replacement rotor, you need to buy the whole assembly with the hub. The steel hub rarely wears out so we decided to make our own replacement rotor. You simply grind off the rivets holding the hub to the old rotor, remove the rivets, and bolt this new rotor to the original hub with the included hardware. Our rotor will last way longer than the stock unit because we use a Grade 50 steel!   We finish it off with a zinc coating to prevent rust.  This rotor is the logical choice for your Polaris ATV!
