2007.5-2010 GM Duramax 6.6L LMM Front Gears

Adding larger tire/wheel combinations to your Sierra/Silverado is simple, but gaining back the lost performance and acceleration can be difficult after you change your final drive ratio. These premium 2007.5-2010 GM 6.6L Duramax LMM front ring-and-pinion gears help yow win back the performance you once had when installing larger tires over stock. Shorter gears give your GM 2500/3500 improved acceleration and torque delivery which can seriously give your rig a boost on and off-road. GM Duramax Fitments: 2007, 2009, 2010 GM 6.6L Duramax.
