Detailed Description

The ACI Window Regulator 384440 is a front left power window regulator designed for vehicles with factory power window operation. As a new replacement part, it is built to restore the mechanical function of the window lift system without requiring a remanufactured component. The plastic gear design supports consistent window travel, while the OE-level specification helps maintain proper fit and function in the door assembly.

This part cross-references OE-style numbers 55359567AA and 55359567AB for the same application. It is a practical replacement for owners searching for a 2005-2011 Dodge Dakota front left window regulator, a 2011 Ram Dakota front left regulator, or a 2006-2009 Mitsubishi Raider front left power window regulator. Part number 384440 is also a useful search reference when matching the correct door-side application.

What It Helps Fix

• Window stuck in the up or down position
• Slow, uneven, or noisy window movement
• Broken regulator gear or internal lift mechanism
• Power window operation that no longer responds correctly
• Driver-side front window that will not track properly

Installation Notes and Tips

Verify the front left position and confirm power window operation before installation. This regulator does not include the motor, so reuse or replace the motor as needed based on the vehicle’s existing setup. Compare the original part number, connector style, and door configuration before installation to confirm the correct ACI 384440 replacement.

Quality Assurance

ACI identifies this regulator as a new part that meets or exceeds OEM requirements. That specification supports consistent replacement quality for Dodge Dakota, Ram Dakota, and Mitsubishi Raider applications where proper window lift performance is needed.
