AA Chassis Overview

The Ford model AA’s were produced from December 1927 through February 1932 except the AA Standrive which was produced through July 1932. The AA’s were rated at 1-1/2 tons (an upgrade from the 1 ton TT rated chassis). The initial AA chassis had a 131-1/2” wheel base. Starting in mid 1930 Ford also offered a 157” AA wheel base chassis. A 112” AA wheel base, Standrive, chassis was introduced in August 1931. These three chassis are referenced as AA131, AA157, or AA112 within this AA Fords site.

The photograph to the left shows what Ford included as a complete AA131. This chassis was offered to customers wanting to add their own body. It included the hood, cowl tank assembly, headlamps, tail lamp, front fenders, running boards, and shields.

Ford issued several releases of a “Parts Price List” booklet covering everything in the photo on the left and some additional parts such as the wheel carriers, cowl lamps, rear view mirror, tools, windshield wiper, and more. Parts were in numerical sequence and sub-divided into groups. Detail information for each grouping of parts is provided as a separate page.
