Choosing the right kit means matching spindle diameter and hub style to your axle. Round bore retainers fit standard spindles, while D-flat versions key against a flattened spindle face for extra anti-rotation security. Confirm axle capacity before ordering, since hub weight ratings determine which nut and retainer size locks in properly.
