Ensuring Longevity and
Performance

  • Manufacturing process of gearbox

    1. Sandblasting and pre cleaning the exterior paint of the gearbox;
    2. Disassemble and perform final cleaning, carefully inspect each component, and replace damaged or severely worn parts with original ZF products;
    3.  Assembly;
    4. Every manufactured gearbox must pass experimental testing;
    5. Spray painting;
    6. Packaging and Storage.
  • Do you provide warranty and fulfill the contract?

    Yes, out of confidence in quality, we offer a one-year warranty for ZF transmission assemblies to domestic users.
  • Will you replace those parts that are close to the wear limit?

    Yes, and it is much higher than the repair standards of our peers: the service life of all remanufactured parts or assemblies must be higher than 80% of that of a brand new gearbox. Providing customers with first-class remanufactured products is our mission as a company.
  • Do maintenance technicians have sufficient repair experience?

    We fully understand your concerns about the quality of remanufactured transmissions,es, that's right. We have over 1500 ZF gearbox overhaul experiences.
  • Give new life to the old gearbox

    If the gearbox malfunctions, quick response and high-quality products are particularly important in the rescue process. Whether you choose to use a remanufactured gearbox assembly or undergo major repairs, it reflects the current value of the faulty gearbox.
