Whether you've added larger tires and want to win back some performance, or you just need some improved traction for your custom diesel build, these 2007.5-2010 GM 6.6L Duramax LMM driveline upgrades are here to help. Front and rear ring-and-pinion gears get your GM 2500/3500 moving quicker off the line while an aftermarket differential provides serious traction to both wheels on a single axle. Add on a differential cover for more fluid capacity and easier maintenance without compromise. GM Duramax Fitments: 2007, 2009, 2010 GM 6.6L Duramax. Submodel Fitments: WT, Custom, LT, LTZ, High Country, 1LT, 2LT, Pro, SLE, SLT, AT4, Denali. Some exceptions apply, please see individual product pages for specific fitments.
