The Holset HE431VE Variable Geometry Turbo (OEM: 2838790) is an advanced unit for ISM and ISC engines.
It resolves VGT actuator sticking issues and fits equipment including Freightliner Century, Kenworth T800, and Volvo VNL trucks.
In stock for immediate global dispatch.
The Holset HE431VE is an advanced Variable Geometry Turbocharger (VGT) designed for modern Cummins ISC, ISM, and ISL engines. As a technological successor to older fixed-geometry turbos like the HX40 series, the HE431VE utilizes adjustable internal vanes to provide optimal boost across the entire RPM range. This results in superior throttle response, improved fuel economy, and more effective engine braking compared to its predecessors.
Our aftermarket HE431VE is engineered to directly address the most common failure points of this model. By using higher-grade materials for the vane assembly and a more robust electronic actuator, we significantly increase the unit’s resistance to the heat and soot that cause sticking and actuator faults. For fleet managers and rebuilders, this means a more reliable replacement part that restores engine performance without the risk of premature failure, making it a smart investment for your Cummins engine overhaul.

A1: Symptom: “Limp mode” activation, fault codes for VGT position, and poor engine response. Diagnosis: In 11L engines like the ISM11, internal soot buildup clogs the sliding vane mechanism, or the electric actuator fails due to coolant ingress. This prevents the turbo from adjusting boost across the RPM range. Solution: Our HE431VE units are built with precision-machined nozzle rings and high-durability actuator seals to resist carbon accumulation and moisture, ensuring smooth VGT operation.
A2: Technical Detail: The VGT actuator must be electronically calibrated to the engine’s ECU using a diagnostic tool, and the coolant lines for the actuator must be checked for flow. Pro-Tip: Never install a 2838790 unit without performing the “actuator sweep” test; failure to calibrate the VGT will cause overboost or underboost, potentially damaging the ISM engine’s internal components.
A3: Diagnosis: The ISM platform operates with varying backpressures to control emissions, leading to high EGTs that can warp the VGT vanes. Our Solution: We use K18 high-nickel alloy for the turbine wheel and the variable nozzle assembly. This material maintains dimensional stability at temperatures up to 850°C, ensuring the 2838790 turbo maintains its boost adjustment precision throughout the engine’s service life.
