• This turbocharger covers multi part numbers VA440031 VB440031 VC440031 and OEM code 8973628390 for matching light duty diesel commercial vehicles

  The turbo adopts integrated aluminum compressor housing and high temperature resistant cast iron turbine housing without external wastegate actuator

  All internal core rotating parts alloy impellers floating bearings and multi layer oil seals are fully preassembled inside the turbo unit

  The four hole turbine mounting flange and compressor intake outlet ports are manufactured strictly according to original vehicle OEM dimensional standards

  This turbo unit serves as a direct swap replacement for damaged original turbochargers of matching diesel engine models

• The cast aluminum compressor housing achieves efficient heat dissipation to avoid thermal deformation under continuous high load driving conditions

  Internal built pressure balance structure maintains stable boost pressure output to guarantee consistent engine power delivery

  Double sided dynamically balanced alloy rotor assembly reduces high speed vibration and eliminates abnormal whistling running noise

  Optimized internal air flow channel layout increases intake air volume to lift low speed torque and improve fuel combustion efficiency

  Thickened nodular cast iron turbine shell resists long term high temperature exhaust corrosion and effectively prevents shell cracking faults

• Every turbo rotor set completes strict high speed double sided dynamic balance testing to eliminate rotor eccentricity and premature bearing wear
• Each finished turbo unit passes full air tightness inspection to block risks of engine oil leakage and intake exhaust gas seepage
• Simulated high temperature aging testing verifies stable working performance under harsh engine compartment high heat environments
• All raw materials for housing impeller bearing and sealing components meet light commercial vehicle OEM quality production standards
• Each finished turbo product carries a unique serial number to realize complete traceability of all production and inspection records

We promise to ship out all orders on time.

• Cost-effective upgrade with high cost-performance ratio compared to original parts
• High filtration efficiency effectively intercepts impurities and protects the engine
• Low pressure drop ensures smooth oil circulation and stable engine power
• Durable material with long service life reduces maintenance frequency
