How To Read Lippert Axle Tag
FORD ID TAGS | GM RPO CODES | DANA SPICER BOM NUMBERS |VISUAL IDENTIFICATION
When repairing or upgrading differential parts, the starting time and most of import step is to place your existing axle / differential. Ensure accuracy by checking the tag numbers or stamps on the axle or by utilizing the RPO codes on GM vehicles.
FORD Axle IDENTIFICATION TAGS
The location of Ford identification tags volition vary by model, only nigh are located on a carrier cover bolt. The Band Gear Size (differential type) and the Gear Ratio will be printed on the tag (equally well as whether or not the differential is express slip).
GM RPO CODES
GM Vehicles come up with RPO codes, which are 3-grapheme codes that designate various features / options on your vehicle. RPO codes tin can be constitute by referencing the Service Parts Identification sticker (typically located in the glove box compartment or near the spare tire), or past scanning a QR lawmaking on 2018 and upwardly GM vehicles (located at the bottom of the driver side door pillar).
These codes incorporate a wealth of information about your specific vehicle's equipment and specifications. The prefix is normally F, G or H when referring to Axle Identification (for instance, G80 means you have limited slip / positraction).
Note: Using the GM RPO codes to identify your beam / differential assumes that the beam / differential has non previously been modified.
DANA SPICER BOM NUMBERS
All Spicer Carrier-Type axles are identified with a manufacturing date (1) and Nib of Material (BOM) number (2) stamped on the correct or left hand tube on driving axles. The BOM number may also be found on the carrier in some models as shown in analogy (2A). The axle / differential model number will often be cast into one of the webs (three). Each axle contains a gear ratio tag (4), and if the axle is equipped with a express slip differential, it will have a tag specifying the type of limited sideslip lubricant to utilize (5).
The BOM postage (two) or Axle Identification Tags (2A) are used to identify Dana axles / differentials. The BOM volition place the model number, the gear ratio, the blazon of axle / differential, and component parts.
- Traditional BOMs are 6 digits followed by i or 2 digits, and showtime with the numbers threescore or 61. On some tags, the outset 2 digits won't appear on the tag, but they must be used to identify the beam. For example, you might see 3994-ane for the BOM, but the threescore has been dropped and the actual BOM is 603994-1.
- Later BOMs tin can start with the starting time 3 digits 200, only these are not typically dropped from the tag.
The BOM may be used with the Dana Aftermarket website to identify all aspects of a particular beam:
- Get to the Dana Aftermarket Media Library (http://media.spicerparts.com/media) and enter your BOM number under "Keyword Search"
- Click on the resulting literature link
- Search for the BOM within the PDF (e.k. for BOM 603994-1, the differential is a standard Dana threescore with a three.73 Gear Ratio)
VISUAL Beam / DIFFERENTIAL IDENTIFICATION
In the absence of an ID tag, axle / differential types can exist identified using the shape of the cover, the number of cover bolts, the number of ring gear bolts, and the band gear bore. Use the images and data listed below to help identify which differential your vehicle has before ordering parts.
CB = Embrace Bolt
RGB = Ring Gear Commodities
Spline = Axle Spline Count
