3.92:1-5.89:1. Units with two piece shafts come as a 19 or 27

CJ Dana 44: Prior to 1972, all CJ Dana 44s had
an offset differential. They also used 19 or 27 spline two piece
axle shafts. After the mid 1970s, they used a 20 spline flanged
axle instead. These Dana 44s use an 11” drum brake, and the most
common gear ratio is 3.73:1.
After 1976, the Dana 44 was rarely seen on the CJ models, with
some exceptions throughout the years. All CJ Dana 44s use a 5 on
5-1/2” wheel bolt pattern.
XJ and MJ Dana 44: Axles will interchange
between these models and use a 5 on 4-1/2” bolt pattern. They were
available on the HD towing or metric ton option for the XJ and

shafts, and have a 5 on 4-1/2” wheel bolt pattern. Common ratios
