Hello!

This is to introduce ourselves as a turbocharger supplier which has many years' experience in this line of business. Our products include many world-famous brands such as Garrett, Holset, KKK, IHI, Mitsubishi etc. We believe that we can become your excellent supplier.

Most of our products are original. And as we know that the dynamic balance performance is very important to turbochargers, therefore, all of our product have undergone rigorous dynamic balance testing, the turbo wheel and compressor wheel can run smoothly at high speed. Besides, oil sealing performance is good, the situation that oil leakage from turbine or compressor will not occur. Some turbochargers may give engine some negative influence, such as power shortage, low boost pressure and black smoke. These will definitely not happen in our products.
