L5P Duramax Reman Turbo Actuator – Grizzly R79-1G01721GT
Restore proper boost control and eliminate common turbo-related drivability issues on your 2017–2019 L5P Duramax with this Grizzly remanufactured turbo actuator.
The electronic VGT (Variable Geometry Turbo) actuator is a well-known failure point on these engines. When it fails, drivers typically experience reduced engine power/limp mode, sluggish or inconsistent turbo spool-up, poor throttle response under load, and diagnostic trouble codes such as P003A and P0046.
This Grizzly reman unit is a direct-fit replacement designed to restore precise control of the turbocharger’s variable vanes. By accurately regulating exhaust gas flow through the turbine, it delivers the correct boost pressure across the RPM range—helping recover factory power, towing performance, fuel efficiency, and exhaust brake function.
Key Benefits
- Direct replacement for 2017–2019 L5P Duramax applications
- Restores proper Variable Geometry Turbo (VGT) vane operation
- Addresses common codes (P003A, P0046) and reduced power conditions
- Improves throttle response, boost consistency, and overall drivability
- Supports better fuel economy and emissions performance when functioning correctly
- 1-year warranty
- Core charge required (refundable upon return of your old actuator)
Fitment
- 2017–2019 Chevrolet Silverado 2500HD / 3500HD 6.6L Duramax L5P
- 2017–2019 GMC Sierra 2500HD / 3500HD 6.6L Duramax L5P
Note: After installation, a vane position relearn procedure with a compatible scan tool is typically required for proper operation.
