TRQ Rear Right Window Regulator Passenger Side - Direct Fit OE

In this review the TRQ Rear Right Window Regulator is evaluated for owners of late 1990s and early 2000s Mercedes E-Class models who need a direct-fit, vehicle-specific replacement. The bottom line: this is a straightforward, value-oriented OE replacement part that fits the listed E300, E320, E420, E430 and E55 AMG rear passenger side applications and restores window operation without modifying the door. Reviewers will appreciate the clear fitment focus and included mounting hardware, but should note the motor is not included and some users report mixed feel in rollability and build quality.

Key Features

• Direct Fit: Designed to match factory mounting points so installers can replace the regulator without fabricating brackets or drilling new holes.
• OE Replacement: Built as a vehicle-specific regulator to restore original window function for compatible Mercedes E-Class years.
• Galvanized Steel Frame: A corrosion-resistant frame material intended to improve longevity in the door cavity.
• Mounting Hardware Included: Comes with the necessary fasteners so the part is ready for installation once the old regulator is removed.
• Aftermarket Reference: Cross-referenced to common replacement number 740453 to help confirm compatibility with parts suppliers.
• Installer-Friendly Design: Upgraded components and a form factor aimed at simpler, quicker installation for independent mechanics and DIYers.

Who It's For

The TRQ rear right window regulator is suited to owners and mechanics working on 1996-2003 Mercedes-Benz E320, 1997-1999 E300, 1997 E420, 1998-2002 E430 and 1999-2002 E55 AMG who need a direct-fit OE-style replacement without the expense of an OEM unit. It is a practical option for those who already have the window motor or are replacing the regulator only.

It is not ideal for buyers who require a replacement that includes the motor or who demand premium, heavy-gauge construction; several users noted mixed feedback on rollability and perceived build robustness, so those seeking a factory-original feel may want to compare options first.

Pros & Cons

Pros

• Direct-fit application saves time and avoids door modification during installation.
• Included mounting hardware reduces trips to the parts store and speeds installation.
• Good value for the money with broad compatibility across E-Class model years.
• Galvanized steel frame helps resist corrosion in the door environment.

Cons

• Motor not included, so buyers replacing a failed motor will need to purchase one separately.
• Some users report mixed rollability and feel, and a few describe the build as less robust than OE.
