2020-2024 GM Duramax 6.6L L5P Differentials

While your GM 2500/3500 is a seriously capable truck, you can give your Sierra/Silverado build big time traction and handling with an aftermarket differential. Aftermarket differentials allow you to put power down to both wheels on a single axle in low-traction conditions, making for a quality upgrade for truck's experiencing loss of traction when off-road. Whether you need a limited-slip, auto locker or manual locker, or selection of differentials is here to help. We even carry a handful of differential covers to make maintenance a breeze while offering up an aggressive look to your truck. GM Duramax Fitments: 2020, 2021, 2022, 2023, 2024 GM 6.6L Duramax.
