The AVP Turbo Wastegate Actuator is a true drop-in replacement for 1996–2000 Chevrolet and GMC 6.5L Turbo Diesel engines equipped with the "GM8" turbocharger. This unit restores proper turbo boost control, helping eliminate common overboost/underboost codes and hesitations caused by failing factory actuators.
Built from premium materials, AVP’s actuator delivers reliable pressure regulation and long service life. The bracket and actuator rod are precision-fit for GM8 turbos, but please compare your old actuator first: this model fits units where the actuator pin faces away from the turbo. Trucks with the pin facing toward the turbo require a different version.
Perfect for Suburbans and pickups using the OE GM8 turbo. No core charge or remanufactured parts—just a new, ready-to-bolt-on solution trusted by diesel professionals.
OE/cross reference part numbers: 12456425, 171200, 12533737, 12556124.
