Bearing retaining ring f/ ZPN 780117

Perfect reproductions of the steel hub assembly but with modern SKF roller bearing assemblies in stead of the old fashioned loose roller-and-cage style bearings. This great improvement however is almost impossible to see when the hubs are installed. Fit front and rear on all 1936-1966 Big Twins, 1936-1952 WLC front and rear, 1937-1952 WL & WLA rear, and 1941-1954 Servi Car front. Hubs come complete with all internal components installed.
