Rebuild your front differential with confidence using this new American Axle & Manufacturing carrier, engineered specifically for GM light truck and SUV applications. Fitting Chevrolet Colorado, GMC Canyon, and Hummer H3/H3T models from 2004-2010, this carrier is built to accept a 3.23+ gear ratio and ships without internal gears, giving installers flexibility to pair it with the correct gear set for their application. As a genuine new component, it delivers a reliable foundation for a proper differential rebuild rather than a masked repair. Since this carrier does not include internal gears, plan to pair it with AAM's 74043199 differential gear kit for a complete, correctly matched setup. Backed by AAM's manufacturer warranty, this part is a solid choice for shops and DIY installers looking to restore original differential function on qualifying GM trucks and SUVs.
