Light Axle Customers
Beginning in December, 1994, a new model numbering system was established for all
new Spicer axles. The new system allows easy identification of an axle assembly by its
metric ring gear pitch diameter. Many of the new axle models can be interchanged with
old models, but the component parts may not be interchangeable. Please contact DSD’s
Tech Service group to verify the correct service parts numbers.
The list of axle models and their functional interchanges are as follows:

designs. All other applications will continue to use the old model numbers.
