Useful Information

Description and Purpose:

This Genuine VGT Short Turbocharger Kit by Cummins in New condition engineered for ISM11 and QSM diesel engines. Part number: 4040649. Model HE400VG / HE451VE equipped with a pre-installed electronic actuator, it delivers dynamic airflow control and boosts engine response under varying loads. Designed to meet emissions requirements and maintain operational efficiency in heavy-duty applications.

Why Replacement is Important:

Worn or malfunctioning turbochargers disrupt boost delivery and exhaust backpressure, risking fuel overuse and engine derate. Replacing the unit prevents costly downtime and preserves emission system integrity.

Impact on Vehicle Performance:

A functional VGT turbocharger enhances drivability, stabilizes combustion at all speeds, and ensures sustained performance under high load or long-haul operation.

Manufacturer Information:

Cummins® powers industries with durable diesel and natural gas engines built for maximum uptime and minimal maintenance.
