Product Description
For LLY, LBZ, LMM
Part Number 773540-5001S (590HP*) Stage 1
The Duramax Stage 1 turbocharger kit features Garrett patented Advanced Variable Nozzle Turbine AVNT™ design for increased compressor and turbine flow. The GT Series wheel design ensures top performance, lower back pressure, and reduces intake and exhaust gas temperatures. The unique design features nine movable vanes which significantly increase turbine efficiency and improve engine performance from idle launch through peak torque. Patented integral electro-hydraulic actuation and proportional solenoid allow for infinitely variable control. Suitable as a performance upgrade or replacement for original equipment. Outline interchangeable with the OE turbo for perfect fit each and every time.
Part Number 773542-5001S (630HP*) Stage 2
The Duramax Stage 1 turbocharger kit features Garrett patented Advanced Variable Nozzle Turbine AVNT™ design for increased compressor and turbine flow. Utilizes nine movable vanes which significantly increase turbine efficiency and improve engine performance from idle launch through peak torque. Patented integral electro-hydraulic actuation and proportional solenoid allow for infinitely variable control. Larger compressor trim (52), plus larger GT40 turbine wheel and vanes. Outline interchangeable with the OE turbo for perfect fit each and every time.
Optional T51R Mod is where we plug and then CNC machine the inlet of the compressor housing to amplify the turbo whine and whistle. Keep in mind this modification is done after the order is placed and typically ads a week or two before the order is shipped. However, sometimes it can take longer and maybe even up to 4 weeks. If you have ordered other finishing options like ceramic or polishing, it may add additional time on top of the typical 2-3 weeks before your order ships. Because of the labor intensive work and machine time needed, there can be delays beyond what we quote. We do take special care to every order to prepare for shipping and want to make sure you get the highest quality parts and service. We are confident that the quality you receive is worth the wait. We appreciate your patience while we work.
