This category also lists two carriers that are not GM applications: a 195mm front carrier for 2011-2013 Durango and Grand Cherokee, 3.09 ratio, without E-Lock, and a 230mm front carrier for 2011-2020 Durango and Grand Cherokee, 3.45 ratio, without E-Lock. Both are Dodge and Jeep units that carry a GM 9.25 axle family tag in our data. If you are shopping for a GM truck, skip those two.

How to identify yours

Start with the ratio. The GM ratios stocked are 3.42, 3.73, 4.10, 4.11 and 4.56. Then use the vendor SKU, which is what actually separates these listings. RAA440-1291A through RAA440-1291H cover the earlier GM 2500 and 3500 trucks, RAA440-1337A and RAA440-1337B cover the 1999-10 Silverado and Sierra, and RAA440-234A and RAA440-234B cover the 2011-2012 trucks. The two Dodge and Jeep carriers are RAA440-1459 and RAA440-1461.

The 2020-2021 listings give a ratio option code and ID codes instead of a vendor SKU. Ratio option GT4 is the 3.73 unit, with IDs AAGX, AAGY, AAMV, AARH, AASB, AASF and AATT. Ratio option GU6 is the 3.42 unit, with IDs AAGY, AAMW, AARJ, AASC, AASD and AATU. Both of those listings also note inside clips on the U-joint cap.
