The SACER Remanufactured Smart Electronic Actuator (K5T77571) is expertly re-engineered for VGT (Variable-Geometry Turbocharger) systems used in medium-duty and heavy-duty diesel engines. It is widely applied in turbocharger control to improve engine efficiency, reduce emissions, and meet strict global exhaust emission standards.
Through SACER’s rigorous professional remanufacturing process, each unit is completely disassembled, deep-cleaned, and rebuilt using high-grade components to restore true OE-level functionality, durability, and reliability.
This actuator precisely controls the turbocharger vane position, ensuring real-time coordination between the engine combustion process and turbocharging system. It helps optimize air intake, improve fuel economy, and eliminate boost lag in demanding HDV (Heavy Duty Vehicle) applications.
