Ram Turbo Actuator Queencar Aluminum Automatic VGT 68445522AA

Description

Product Overview

The Queencar Ram Turbo Actuator is a vehicle‑specific component engineered for the demanding environment of 6.7L Cummins diesel trucks. Constructed from high‑grade aluminum, the actuator combines lightweight durability with excellent heat dissipation, ensuring long‑term reliability even under continuous high‑boost conditions. The unit conforms to OE specifications and carries the OEM part number 68445522AA, guaranteeing a direct fit for the designated engine models. Its threaded inlet and outlet connections simplify installation while providing a secure seal against fuel and oil leaks. The actuator operates in an automatic mode, delivering precise variable geometry turbo (VGT) control that optimizes boost pressure across a wide range of engine speeds. The flush‑mount design integrates seamlessly into the engine bay, preserving the original aesthetic and minimizing the need for additional brackets or modifications. With a weight of just 4.2 pounds and compact dimensions of 9.57 x 7.24 x 6.81 inches, the actuator is easy to handle during service, yet robust enough to withstand the harsh vibrations and thermal cycles typical of heavy‑duty truck operation.

Usage

This actuator is intended for use in Dodge Ram 2500, 3500, and 4500 ISB models equipped with the 6.7L Cummins diesel engine, covering model years from 2013 to 2018. It is also compatible with earlier turbocharger versions when paired with the included wiring harness adapter, extending its applicability to trucks from 2007.5 to 2012. The actuator excels in applications that demand rapid boost response, such as towing, off‑road excursions, and high‑performance hauling. By automatically adjusting the turbo’s vane position, the actuator maintains optimal airflow, reducing turbo lag and improving fuel efficiency. Installation is straightforward: the threaded connections align with the existing inlet and outlet ports, the flush‑mount brackets attach to the engine block, and the calibration box ensures the actuator communicates correctly with the vehicle’s electronic control unit (ECU). The product package includes the actuator, an installation kit, a calibration box, and a step‑by‑step tutorial, providing everything a technician needs for a complete retrofit or replacement.
