The GTB4502 Low Pressure Turbocharger is an OEM-spec replacement designed for John Deere 9.0L Final Tier 4 engines, providing efficient airflow and durability for heavy-duty agricultural and industrial applications.
The GTB4502 Low Pressure Turbocharger (PN 951129-5001S) is engineered to support the airflow demands of John Deere 9.0L Final Tier 4 diesel engines, working in conjunction with the high-pressure turbo to maintain optimal engine efficiency and emissions compliance.
This turbocharger is specifically designed for low-pressure, high-flow operation, ensuring stable boost delivery under sustained loads common in agricultural, construction, forestry, and stationary power equipment.
In John Deere 9.0L Final Tier 4 applications, the GTB4502 low pressure turbocharger is paired with the GT3582VH high pressure turbocharger as part of a factory two-stage turbo system. The low pressure stage delivers high-volume airflow, which is then compressed further by the high pressure turbo to meet engine load and emissions requirements.
Built to OEM specifications, the GTB4502 integrates directly with factory exhaust, intake, and aftertreatment systems, making it a direct-fit replacement without tuning or calibration changes when installed in approved applications.
