This unit features a cast iron turbine housing with an integrated pneumatic wastegate actuator for boost control, an aluminum compressor housing, and a rotor assembly supported by a full-floating journal bearing system lubricated by engine oil. The compressor wheel utilizes extended tip technology for improved efficiency at high pressure ratios. The turbine housing incorporates an 8 cm² A/R ratio on specific variants (e.g., 2834798) optimized for the 5.9L displacement torque curve. This assembly serves as a direct replacement for OEM part numbers 4955754, 3960478, and 4035253. Major compatible applications include Dongfeng Tianlong heavy-duty trucks equipped with DCEC Cummins engines, King Long buses utilizing Cummins or Yunnei D25 powerplants, Freightliner trucks with Cummins ISB6 engines, and Dodge Ram 2500/3500 pickups with 6BTAA 5.9L engines. Construction machinery fitment covers Hyundai, Komatsu, and XCMG excavators powered by Cummins 6BT/QSB engines.
