Keep your drivetrain safe during water crossings with the TR-BT001 Diff Breather Kit. Deep water fords pose a serious risk—standard breather systems can allow water to be drawn into your differential housings and gearbox, leading to expensive internal damage. This kit solves the problem by elevating your breather outlet to a higher position on your vehicle, ensuring your diffs, transfer case, and gearbox can breathe freely while staying protected from water intrusion. A must-have upgrade for any off-roader tackling water obstacles above axle height.
