Identify your Axle Assembly using Tags, Codes and Visual Clues

The first and most important step in any differential repair or ratio change is accurate differential identification!

Careful identification of the differential you are working on will make sure you get the right parts for the job the first time. Need help with your differential identification? Call Sierra Gear & Axle at (800)792-2714. Our differential experts are available from 8am to 5pm PST Monday thru Friday.

Dana Spicer and Ford Differentials can be identified most accurately by the tag number or axle tube stamp.

Go to: Differential Tags

Information about Differentials in GM vehicles can usually be obtained by looking at the RPO or “Regular Production Option” codes contained in the Service Parts Identification tag in the glovebox.

Go to: GM RPO Codes

Whenever possible, reference the tag numbers when ordering parts for your Differential. If the ID tag or stamp is missing or unreadable, differentials can be identified by the number of cover bolts, the distinctive shape of the cover, the number of ring gear bolts, and ring gear diameter. They can also be identified by whether the center section is an integral or dropout design. The chart below shows various differential covers, 3rd Members and housings.
