Find New OEM transfer case assemblies and components for GM vehicles. Our factory-original transfer cases and related components are sourced from GM surplus — the correct gear ratio, mode selection, and output shaft configuration for your AWD or 4WD drivetrain.

The transfer case must be matched to your vehicle's transmission output speed, front and rear axle ratios, and traction control calibration. An OEM replacement transfer case maintains all of these parameters — ensuring correct 4WD engagement, proper AWD torque split, and compatibility with your vehicle's electronic stability system.

Transfer case replacement requires proper fluid fill, driveshaft alignment, and traction system calibration verification. Verify part numbers against your vehicle's drivetrain option codes before ordering.
