Turbo Actuator for Cummins B6.7 | Replaces 3788936 3778619 3778623 3784299

The Turbo Actuator for Cummins B6.7 Engine is a critical electronic control component responsible for regulating turbocharger vane position to ensure optimal boost pressure, engine response, and emissions performance. Designed as a direct replacement for Cummins part numbers 3788936, 3778619, 3778623, 3784299, 3784386, and 3785180, this actuator is engineered to meet OEM specifications for accuracy, durability, and reliability.

This turbo actuator precisely controls variable geometry turbocharger (VGT) operation, allowing the engine to deliver strong low-RPM torque, improved throttle response, and consistent power across varying load conditions. Manufactured using high-quality electronic components and a rugged housing, it is built to withstand heat, vibration, and harsh diesel operating environments.

A failing turbo actuator can cause reduced engine power, poor fuel efficiency, turbo lag, fault codes, or limp-mode operation. Replacing it with this Cummins B6.7 turbo actuator restores proper turbocharger function, improves drivability, and helps maintain emissions compliance. It is ideal for engine repairs, turbocharger service, and preventative maintenance on commercial, industrial, and off-highway Cummins B6.7 applications.
