Piaggio D6740487Z01 Front Left Door Rear Window Guide – Porter and Quargo

The original Piaggio rear glass run for the front left door, code D6740487Z01, is the channel along which the window glass of the driver's side door slides in Porter and Quargo vehicles. It is a polished chrome metal profile, with the lower end bent into a bracket and a coupling tab (as observed from product photographs). It keeps the glass aligned as it moves up and down: when it wears out or deforms, the window rattles, vibrates, and makes noise while driving.

Who it's perfect for

For those who use a Porter or Quargo for work and don't want to live with a rattling window. It's one of those parts that nobody notices until it stops working: when the guide wears out, the glass develops play, rattles over bumps, tilts when going up, and eventually strains the window regulator mechanism, which costs much more. Replacing it is a half-hour job that fixes the entire door — and on a vehicle from 1998 as well as one from 2020, the code is the same.

Frequently Asked Questions

How do I know if the window guide needs replacing?
The glass moves sideways when you push it with your hand, rattles over bumps, goes up crooked, or gets stuck halfway. Often, you also hear a whistling sound of air while driving because the window doesn't close flush.

Is this the front or rear guide?
It is the rear guide, meaning the one towards the rear pillar, of the front left door. On the Porter, there are four guides, and they must be ordered by position and side.

Is it also suitable for the Quargo?
Yes, the official catalog indicates this code for both the Quargo 2007-2017 and the Quargo Diesel 750 cc 2004-2006.

Do I need anything else for installation?
Only tools to remove the door panel. The screws are reused. If the exterior weatherstrip is also worn, it's advisable to change it during the same intervention.

Does shipping originate from Italy?
Yes. We ship from Cercola, in the province of Naples, with tracked courier.
