Description:

Mile Marker NP203 4x2 Conversion Bearing Kit is engineered as a direct service replacement for previously installed Mile Marker NP203 4x2 conversion systems including part numbers 501, 502, 503, and 505. Designed for 1973 to 1979 Ford, Dodge, and GM vehicles equipped with New Process 203 transfer cases, this bearing kit restores proper operation and long-term durability to converted part-time systems. Over time, bearings within any transfer case conversion assembly are subject to wear due to load cycles, heat, and drivetrain stress. This replacement kit provides the necessary high-quality components required to maintain smooth operation, proper shaft support, and reliable performance in demanding driving conditions. Precision-manufactured to meet the specifications of Mile Marker?s NP203 conversion assemblies, this kit ensures continued drivetrain efficiency and dependable engagement. Ideal for rebuilds, preventative maintenance, or long-term restoration projects, the NP203 replacement bearing kit helps extend the service life of your part-time conversion system while maintaining the performance standards Mile Marker is known for.
