ACI Window Regulator 81752 for Mercedes-Benz E-Class

ACI 81752 is a new power window regulator for the front left door, built with a hardened steel gear for dependable window movement. It meets or exceeds OEM requirements and is specified for Mercedes-Benz E320, E430, E55 AMG, E300, and E420 applications.

The ACI Window Regulator line focuses on direct-fit replacement parts for door glass operation. This ACI 81752 regulator is a power window regulator with no motor included, making it a practical replacement when the original regulator mechanism is worn, noisy, or no longer moving the glass correctly.

Key Features

  • Power window regulator for the front left position
  • Hardened steel gear for strength and consistent operation
  • New replacement part
  • Meets or exceeds OEM specifications
  • Motor not included
  • Mounting hardware not included

Detailed Description

This ACI 81752 window regulator is engineered for Mercedes-Benz E320, E430, E55 AMG, E300, and E420 models with front left power window applications. It is a direct replacement style part designed to restore proper glass travel in the driver-side front door on the listed vehicles. The hardened steel gear supports smooth regulator movement and long-term durability under normal door use. If you are replacing a worn Mercedes-Benz E320 front left window regulator or sourcing an ACI 81752 replacement for an E430 or E55 AMG, this part provides the correct regulator type without the motor assembly.

This part cross-references Genuine 2107201146 for the same application.

What It Helps Fix

  • Window glass that will not raise or lower properly
  • Grinding, slipping, or uneven window movement
  • Broken or worn regulator gear mechanism
  • Slow or intermittent power window operation
  • Driver-side front window that drops out of alignment

Installation Notes

Verify the front left position and compare the original regulator to ACI 81752 before installation. Transfer or reuse the window motor if your vehicle uses a separate motor assembly, since the motor is not included. Confirm door trim, glass attachment points, and regulator mounting locations match the original part before final assembly.

Quality Assurance

ACI lists this regulator as a new part that meets or exceeds OEM requirements. The hardened steel gear is selected to support reliable window operation in daily use.
