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 second inspection is conducted during the reman process to ensure all component parts meet OEM specifications
  • 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.
  • All cases are cleaned utilizing our state of the art hydro blasting and rinsing process. This process is what brings all cases back to the OEM finish. Once you’ve seen it, you’ll understand what we mean.
