2001-2004 GM Duramax 6.6L LB7 Differentials
The stock 2001-2004 GM Sierra/Silverado 2500 and 3500 trucks are more than capable when it comes to towing and off-roading, but you can give your GM 6.6L Duramax LB7 build big time traction and handling with an aftermarket differential. These high-quality differentials work by putting power down to both wheels on a single axle in low-traction conditions, making them the perfect upgrade for dedicated off-road builds and truck's that see a lot of towing applications. 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: 2001, 2002, 2003, 2004 GM 6.6L Duramax.
