ReTech transfer cases have been re-manufactured to meet or exceed OEM specifications for quality, fit, and performance.

Each transfer case is tested at a state-of-the-art computerized test center administered by ReTech after going through an extensive re-manufacturing process. Case halves were inspected for cracks, stripped threads, and internal wear. All internal parts were inspected for chain stretch and main shaft straightness. Viscous clutch torque testing was done to ensure quality and performance. A spin test procedure was done for shift-ability and noise. All seals are brand new and bearings are certified to manufacturer's specifications. The OEM cores are processed as individual units throughout the process. Cores are cleaned using a hydro blast cleaning and rinse process. Case halves and internal parts are blasted in zinc cut wire to exceed OE appearance specifications. They are also wet sanded to ensure perfect mating surfaces. A loctite gasket eliminator and primer is used to seal all aluminum mating surfaces. Air pressure leak down test is used to ensure all components are free of leaks.
