Transfer case plastic parts KIT (ATC13-1)

The plastic oil deflectors are critical for directing lubricant to the internal gears and bearings. Over time, heat and friction can cause these plastic parts to become brittle or crack. If they fail, the transfer case won’t receive proper lubrication, leading to rapid wear and expensive mechanical failure.

Common signs include a shuddering or jerking sensation during acceleration, unusual grinding noises from the drivetrain, or a 4×4 system warning light. These issues often stem from inadequate oil distribution caused by broken or warped deflectors.

This kit is specifically engineered for the BMW ATC13-1 transfer case. To ensure compatibility, you should verify the transfer case type on your vehicle’s identification plate or consult with a specialist if you are unsure which unit is installed in your X-Drive model.

Replacing the ATC13-1 plastic kit requires opening the transfer case, which is a complex task. Because it involves precise assembly of internal components, we strongly recommend having the installation performed by a professional technician specializing in drivetrain repairs.

Yes, this kit is manufactured to meet or exceed the original specifications. It is designed to withstand the high temperatures and constant oil exposure found inside the ATC13-1 unit, ensuring reliable long-term performance.
