Transfer case plastic parts KIT (ATC350)

These plastic components are critical for the lubrication system. They act as guides to deliver oil directly to the internal bearings and gears. Without them, the transfer case would suffer from dry spots, leading to rapid wear, overheating, and eventual mechanical failure.

If these parts fail or become dislodged, you may experience jerking during acceleration, shuddering while turning, or grinding noises coming from the drivetrain. Often, these symptoms are caused by the internal components not receiving enough oil flow.

This kit is specifically designed for the BMW ATC350 transfer case, which is commonly found in F-series models like the 5 Series (F10), 7 Series (F01), and 6 Series (F06/F12). If your vehicle is equipped with the ATC350 unit, this kit is the correct fit.

Replacing these parts requires opening the transfer case housing. While it is a straightforward replacement once the unit is open, we recommend professional installation or a high level of DIY experience, as it involves removing the transfer case from the vehicle.

It is not recommended. Plastic becomes brittle over time due to heat cycles and oil exposure. When performing a rebuild or repair, installing a new kit ensures that the lubrication system won’t fail shortly after the unit is resealed.
