Quick Ship SKU #: NG-GPDURAMAX2-Main Nitro Complete Ring and Pinion Gear Package 11-16 GM Duramax

Tracking down all of the pieces for a ring and pinion upgrade can be a chore, but not anymore! This complete package from Nitro Gear includes the front and rear gears, as well as a complete Master Installation Kit for both differentials. All you need to do is decide what gear ratio you want to run!

IMPORTANT NOTE: Until model year 2013, AAM utilized an 11.5 assembly. Nitro utilizes the same size gears throughout, but you will need a different gear package depending on how your truck was equipped from the factory. For reference, the 4.30 ratio will utilize the updated 11.8.

In the past, when it was time to upgrade the gearing in your axles, you would have to get a multitude of different parts, sometimes from different suppliers to get the job done. Obviously, you need the ring and pinions, but then you needed bearings, seals, shims, gear bolts, and the list goes on. NO LONGER! Nitro Gear has simplified this process with their complete packages that includes everything you need (besides oil and a pair of hands) to upgrade the ring and pinions in your front and rear differentials.
