2007.5-2010 GM Duramax 6.6L LMM Differentials

Straight off the factory line your 2007.5-2010 GM 6.6L Duramax LMM is a capable truck to say the least, but you can give your Sierra/Silverado big time traction and handling with a new aftermarket differential. Aftermarket differentials offer up a huge improvement in traction and grip so your GM 2500/3500 can conquer any terrain on the planet. These performance differentials will also throw down power and torque to both wheels on a single axle so your truck can find more traction during heavy-duty towing and off-road 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: 2007, 2009, 2010 GM 6.6L Duramax.
