Excellent quality U.S. made cast iron brake drums; almost a must when redoing your entire brake system. Old original brake drums should be no less than .130 thick.
The ID of new drums is 11". New cast iron brake drums should be turned no less than .090" or to a diameter of 10.910". We machine our drums slightly undersize so you have extra material to true up once you assemble to your hubs. U.S.A.
This kit replaces your original A-2051 wedge studs and allows the brake wedge to float which allows the brake shoes to equalize pressure giving better brakes. One kit does both front wheels. U.S.A.
