Early Ford Beam Axle Identification and Dimensions

The different early Ford axles are easy to identify by referring to the picture below, which was scanned from an old magazine article by Neal East.

1928-1931 Model A axles have a uniform curve from end to end. The spring perch bosses are 2 1/4 inches.

1932 axles were the first Ford axles to be made with a slight drop. These axles are often referred to as 1932 heavy axles. They are unique among early Ford axles in having a wider recess at the ends, and a slightly raised area on the front and back of the spring perch bosses in the shape of an I-beam. The spring perch bosses are two inches.

1933-1936 axles have narrower recesses at the ends and along the center compared to the ’32 axles. The spring perch bosses are two inches.

1937 V8-60 axles the only early Ford axles that are hollow forgings. They are flat along the front and back, so their cross-section resembles an oval track with short straightaways. They are relatively lightweight and not recommended for heavier cars. Their spring perch bosses are 2 1/4 inches.
