the 1951-54 Allstate, designed to sell through and by Sears-Roebuck department stores in the southern United States, was a slightly restyled Henry J.

 The cars were equipped with Allstate products (tires, battery, etc.). The modest styling changes distinguishing the Allstate from the Henry J were executed by Alex Tremulis.

The Henry J, while a well-meaning idea, but was hamstrung by various government requirements stemming from a re-capitalization loan the government made to the company in the fall of 1949 . Kaiser-Frazer labor agreements resulted in the company paying the highest wages of any American automaker and getting a productivity rate of only 60–65% in return

Kaiser-Frazer was able to work out deals with General Motors not only to get the GM Hydra-Matic automatic transmissions but had a signed deal for detuned Rocket 88 engines from Oldsmobile with deliveries starting in the 1952 model year. The deal was contingent on Olds being able to expand its Lansing, MI engine production facility; that expansion was cancelled due to factory expansion restrictions put in place by the government due to military needs during the Korean War

In 1950 Kaiser-Frazer began production of a compact car, the Henry J and ended production of the Frazer automobile ; both makes were 1951 model year automobiles. In 1952 and 1953 Kaiser-Frazer provided Sears Roebuck & Co. with Allstate-branded automobiles that Sears sold through selected Sears Auto Centers; these cars, extensively based on the Henry J Kaiser-Frazer dealers were selling did appear in the Sears "wish books" but the car could not be purchased by mail order

At the 1953 annual stockholders' meeting, Kaiser-Frazer Corporation's name was changed by stockholder vote to Kaiser Motors Corporation . Shortly before meeting, Kaiser-Frazer's Kaiser Manufacturing Corporation division worked out a deal to purchase certain assets (and assume certain liabilities) of the Willys-Overland Corporation, makers of Willys cars and Jeep vehicles . The purchase was made by Kaiser-Frazer's wholly owned subsidiary company, Kaiser Manufacturing Corporation. After completing the acquisition, Kaiser Manufacturing Corporation changed its name to Willys Motors, Incorporated . During late 1953 and 1954, Kaiser Motors operations at Willow Run Michigan were closed down or moved to the Willys facility in Toledo, Ohio .
