Turbocharger Actuator Overview

This Dorman turbocharger actuator, part number 668-536, is a standard replacement for select Ram heavy-duty trucks with 6.7L I6 diesel engines. It uses an electronic activation design and is remanufactured to help restore factory-spec turbo output.

Built for Ram 2500, Ram 3500, Ram 4500, and Ram 5500 applications, this actuator addresses a known failure point in the original design by using soldered compliant pins for a more secure connection to the circuit board. Part number 668-536 is remanufactured in the USA and thoroughly tested before release.

  • Electronic turbocharger actuator for variable geometry turbo systems
  • Remanufactured standard replacement with aluminum and plastic construction
  • Upgraded internal connection design for improved electrical reliability
  • 4-terminal male blade connector configuration
  • Fits select Ram diesel truck applications with factory turbo control systems

Product Details

Dorman 668-536 is engineered as an OE FIX solution for applications where the original variable geometry turbocharger actuator can fail from internal connection separation and heat-related electrical issues. The remanufactured design uses soldered compliant pins to create a more secure link to the printed circuit board assembly, helping maintain consistent turbo control under normal operation. This part cross-references Chrysler/Mopar R8444773AA for the same application.

Common Repair Uses

  • Restores inconsistent turbocharger vane control
  • Addresses actuator failure caused by internal electrical connection issues
  • Helps correct reduced turbo output or poor boost response
  • Replaces a worn or malfunctioning electronic VGT actuator
