Piaggio 6633187Z01000 Rear Tailgate Buffer - Porter Petrol, Diesel, Maxxi and Electric (1992-2020)

The Piaggio 6633187Z01000 support buffer is the original Piaggio Group spare part against which the Porter's tailgate rests. It is a block of black rubber with a saddle-shaped seat, which absorbs the closing impact and vibrations of the bar (observed from product photographs): when it crumbles or disappears, the tailgate slams against the metal, vibrates while driving, and the bodywork gets marked. It costs a few euros and is snap-on, no screws required.

Who it's perfect for

It's the classic cheap part that no one orders until it really becomes annoying. On a working Porter, the tailgate opens and closes dozens of times a day: the buffers get squashed, break, and eventually detach. From that moment on, the tailgate slams against the metal every time it closes, rattles over bumps while driving, and the sheet metal starts to get marked and chipped. Replacing them takes minutes and restores quiet closing. It applies to all Porters: petrol, LPG, methane, diesel, Maxxi, and electric, from 1992 to 2020.

Frequently asked questions

Which Porters does it fit?
It fits the entire range: Porter 1000-1300 Pick-Van (1992-2009), Up-Date (2009-2010), Multitech E4, E5, E5+, E6, E6-C and Entry Level (2010-2020) also in Maxxi version, D120 E5 diesel standard and Maxxi (2010-2015), Pick 1400 diesel (1998-2005) and Electric Up-Date and EVO (2009-2020). The list comes from the official Piaggio spare parts catalog.

How many are needed?
The price is for one piece. There is more than one on the vehicle: check how many your Porter has and order them all together, as they wear out at the same rate.

How do I know it needs changing?
The buffer is squashed, broken, or completely missing. Symptoms include a sharp thud when closing the tailgate, noise over bumps, and impact marks on the sheet metal at the contact point.

Are screws needed for mounting?
No. The buffer has two grooved pins that snap into place: just clean the housing of any old residue and push the new one into position.

Is it original or an equivalent?
It is an original Piaggio Group spare part, code 6633187Z01000. A generic buffer of the wrong size will not hold the tailgate in place and will come off quickly.

Can I install it myself?
Yes, it is one of the few Porter spare parts that can be changed without special tools: remove the old one, clean the seat, and snap in the new one. Five minutes per buffer.
