The Chrysler Corporation began producing the M4A3 (76) in March 1944 Many of their first units arrived almost simultaneously in France &38; Italy in August 1944 It like all the Shermans saw a steady flow of minor improvements & versions of this tank with HVSS (horizontal volute spring suspension) started arriving in December of 1944 just prior to the Axis push into the Ardennes region & would become increasingly common from that point on as replacement tanks entered the combat zone These tanks were very well received the Ford GAA was a very good engine for a tank in the Sherman's weight range
