This Kit is for use with your standard 3500 lb Trailer axle and mounts to your 4 Hole Brake Flange. In order to use the Slip Over style of Kodiak Trailer Rotor, you must have 14 inch wheels or greater, it will not not mount in 13 inch wheels. Using Kodiaks Slip Over Rotors will add about 1/2" to the over length of your Axle/Tire and wheel Assembly. This means that the axle with Slip Over brakes will extend 1/4" further than the Axle without brakes (on a tandem axle set up), which is not an issue and will not cause any problems.
