All of our Transfer cases are remanufactured using strict specifications to ensure a quality build, and to give you peace of mind when reselling to a customer or installing in a vehicle.

  • Quality inspections are conducted 3 times during the remanufacturing process
  • A pre-inspection is done to ensure the unit is free of case cracks, excessive wear and to catch other OEM related problems that many cores have

  • A final post-build inspection is done to ensure unit is built to our strict standards
  • All units are quality inspected throughout the remanufacturing process to maintain our quality standard.
