Upgrade the turbocharger on a 2024-2026 L5P Duramax with VSE's G3 64/66 design. The combination is developed for responsive towing and street use, with increased turbine-side flow and retained variable-geometry exhaust-brake operation.

• 64 mm titanium-nitride-coated billet compressor.
• 76 x 66 mm nine-blade turbine and proprietary 11 mm vane cage.
• Upgraded thrust plate, thrust bearing and journal bearings.
• Direct replacement that VSE states can operate on the factory calibration.
• No core return required.

Application notes: Custom tuning is recommended to make full use of the upgraded airflow. This version is for the 2024-2026 truck generation; earlier trucks require a conversion package.
