It’s a used, 16.5‑inch diameter by 8‑inch wide shoe with premium 23,000‑lb GAWR lining. You would replace this shoe when the friction lining wears below safe thickness, and return the old core to recover the core charge when purchasing a remanufactured kit. This core matches the Alliance/Meritor 4718 Q Plus configuration commonly found on drive and trailer axles.
