Restore xDrive performance with this OEM-quality BMW ATC35L transfer case assembly. Direct replacement for F10, F30, F34, F36 models to eliminate drivetrain vibration, jerking, and transfer case faults.

Restore your BMW’s xDrive system to factory performance with this OEM-quality ATC35L transfer case assembly. The transfer case is the heart of BMW’s intelligent all-wheel-drive system, responsible for distributing torque between the front and rear axles to deliver maximum traction, stability, and performance in all driving conditions.

If your BMW is experiencing drivetrain vibration, jerking, grinding noises, or transfer case malfunction codes, replacing the complete assembly ensures reliable power delivery and prevents costly downstream damage to the transmission or driveshaft.
