Rear Bumper Overrider 

Restore the authentic appearance and protection of your classic Porsche with this OE Match Rear Bumper Overrider, designed specifically for the Porsche 356B and Porsche 356C. Manufactured to original equipment specifications, this premium replacement bumper overrider provides the correct factory profile, high-quality finish and precise fit, making it ideal for concours restorations, accident repairs or replacing damaged original components.

Fits:

• Porsche 356B 1959-63
• Porsche 356C 1963-65

Positioned on the rear bumper, the overrider provides additional protection against minor impacts while preserving the distinctive styling that defines the iconic Porsche 356.

What Does the Rear Bumper Overrider Do?

The rear bumper overrider is both a protective and decorative component that mounts to the rear bumper.

Its primary functions include:

• Providing additional protection during low-speed impacts.
• Helping minimise damage from parking knocks.
• Protecting the rear bumper from minor contact.
• Reinforcing the classic factory styling.
• Completing the original bumper assembly.
• Enhancing the appearance of restored vehicles.

The bumper overrider is an essential finishing detail that contributes to both the originality and practicality of the Porsche 356.

Why Do Rear Bumper Overriders Fail?

After decades of use, bumper overriders can deteriorate due to:

• Minor parking impacts.
• Road accidents.
• Corrosion beneath damaged chrome plating.
• Stone chips causing surface damage.
• Moisture exposure.
• Poor previous repairs or ageing chrome finishes.

As damage develops, the overrider can lose its appearance, structural integrity and ability to protect the bumper.

When Should the Rear Bumper Overrider Be Replaced?

Replacement is recommended whenever you notice:

• Dented or distorted overriders.
• Peeling or pitted chrome.
• Corrosion beneath the surface.
• Damage following minor collisions.
• Poor alignment.
• During complete bumper refurbishment or concours restoration.

Replacing worn bumper overriders restores both the appearance and functionality of the rear bumper assembly.

Front Bumper Overrider.
The OE Match Front Bumper Overrider is a premium-quality replacement bumper protection component designed to restore the original appearance and functionality of the front bumper on compatible classic Porsche models. Manufactured to OE specifications for fit, profile and durability, these overriders provide additional protection against minor impacts while maintaining the authentic factory styling of the vehicle.  

Fits:

• Porsche 356B 1959-63
• Porsche 356C 1963-65  

Manufactured from high-quality steel with a durable corrosion-resistant finish, the overriders are engineered to withstand exposure to road debris, moisture, UV radiation and everyday driving conditions. Precision-manufactured for direct OE-style installation, they fit securely to the original bumper mounting points, making them the ideal replacement for worn, damaged or corroded original overriders during restoration or repair.  

What This Product Does:

• Provides additional protection for the front bumper.
• Helps absorb minor impacts during low-speed manoeuvres.
• Protects the bumper from scuffs and parking damage.
• Restores the original appearance of the front bumper assembly.
• Maintains factory-style fitment and alignment.
• Enhances the authentic styling of classic Porsche models.
• Replaces worn, damaged or corroded original overriders.

Symptoms Of Wear Or Failure:

• Corrosion or rust on the overrider.

• Misalignment with the bumper.

• Cosmetic deterioration affecting the vehicle's appearance.
• Damage caused by parking knocks.
• Reduced protection for the bumper assembly.

Why Replacement Matters:

• The front bumper overrider is constantly exposed to road debris, stone impacts, moisture, road salt and minor parking contact. Over time, corrosion, impact damage and general wear can affect both its appearance and structural integrity.
• A damaged or loose overrider can reduce the level of protection provided to the bumper while detracting from the vehicle's original appearance. On classic Porsche models, maintaining correctly fitted bumper components is essential for preserving authenticity, structural integrity and long-term vehicle value.
• Replacing worn or damaged front bumper overriders restores the original appearance of the bumper assembly while providing renewed protection against everyday impacts. The OE Match replacement offers factory-style fitment, durable construction and a high-quality finish, making it an ideal choice for restoration projects and long-term maintenance of your Porsche.

Bumper horn piping seal. 1700MM.
Genuine Porsche Original Equipment (OE) bumper guard beading strip - often described as bumper horn piping seal or bumper piping beading. It is a rubber sealing/trim strip designed to fit along the edges of the front or rear bumper overriders (horn guards) on classic Porsche models.

Fits:
Porsche 911/912 1965 - 1973
Porsche 356B / 356C 1960 - 1965

Diagram ref no 9

The bumper guard beading/bumper horn piping seal provides a protective, weather-resistant edge between the rubber or chrome bumper guard and the surrounding body/bumpers. It hides gaps and edges, prevents water/mud ingress behind trim, cushions minor knocks, and completes the look of the bumper assembly in line with factory design.

Function:
Installed along recesses in the bumper overrider or horn area, this beading:
•  Fills and seals gaps between the bumper guard and the bumper body
•  Protects finished surfaces from scratches and edge wear
•  Helps retain trim fitment under vibration
•  Preserves original appearance and detail on classic Porsche models

Original bumper beading on classic Porsche models often becomes brittle, cracked, or stretched over decades of exposure to sun, moisture, and road debris. Worn or missing beading detracts from the overall appearance and can allow moisture, dirt, and corrosion to develop behind bumper trim. Replacing with a fresh beading restores the correct factory look, protects costly bodywork and trim, and helps maintain value for classic vehicles.

When to replace:
•  Beading is cracked, brittle, or split
•  Original strip has shrunk or deformed
•  During bumper removal/install
•  As part of bodywork restoration Prior to concours or show preparation

Bumper horn piping seal. 1m.
(1m front and 1m rear needed)

This flexible rubber beading trims and seals the interface between the bumper horn (overrider) and the main bumper body, providing a clean, finished look and helping protect against moisture, dirt, and minor abrasion.

Fits:
Porsche 911 2.0-2.4 01/1963 - 07/1973
Porsche 912 1.6 01/1965 - 02/1970

Diagram ref no 9

The piping seal installs easily into the original grooves and mounting channels on the bumper profile, forming a neat protective edge that enhances both aesthetic and functional performance. It is ideal for classic restoration projects, bumper reassembly after removal, or when refreshing aging or brittle original piping.

The bumper horn piping seal bridges the gap between the chrome/painted bumper horn and the adjacent bodywork by providing a soft, contoured edge. It helps:
• Mask raw edges and transitions between components
• Protect surrounding paint and finishes from minor contact damage
• Reduce the ingress of dirt, water, and road debris behind the bumper trim
• Restore the classic factory-correct appearance of the bumper assembly.

Function:
Installed along the perimeter of the overrider (horn) section of the front or rear bumper, this rubber piping compresses slightly to grip the bumper and horn edges. Its profile maintains a consistent seal while allowing normal flex and vibration without loss of fit - preventing rattles and movement that can occur with brittle, aged original beading. 

With age, original bumper horn piping often becomes brittle, cracked, deformed, or lost, exposing underlying edges and hardware. This can detract from the vehicle’s appearance and allow water and debris to sit behind the bumper, potentially trapping moisture and accelerating corrosion. Replacing it with an OE Match seal restores the look and function of the factory assembly - preserving both style and protective qualities.

When to replace:
•  Original piping is cracked, shrunken, or missing
•  Bumper horn or overrider has been removed for service
•  Preparing a vehicle for restoration, sale, or show
•  When reassembling bumped or replaced bumper trim
•  Preventive refresh on aging rubber components
