Quick Ship SKU #: NG-GPDURAMAX-Main Nitro Complete Ring and Pinion Gear Package 01-10 GM 8.1L 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!

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.

And for those that will be upgrading to the 4.30 ratio, you will get the added bonus of an 11.8" ring gear for added strength over the factory 11.5! This is the same size ring gear that AAM went to in model year 2013 to increase the overall durability of the rear end.
