Bumper bellows, Front and Rear set. Porsche 911/930 1974-89  ❭  BUMPERBELLOWSET

This set of four bumper bellows includes the following:
•  Front bumper – OE Match LEFT impact-tube bellows (OE ref no: 91179950513)
•  Front bumper – OE Match RIGHT impact-tube bellows (OE ref no: 91179950514)
•  Rear bumper – OE Match LEFT impact-tube bellows (OE ref no: 91179950515)
•  Rear bumper – OE Match RIGHT impact-tube bellows (OE ref no: 91179950516)

Each bellow is manufactured to replicate the original Porsche specification: correct corrugated profile, rubber compound, precise mounting holes and correct dimensions for the impact-tube housing. These bellows sit between the bumper tube and chassis mount (front and rear) on the 911/930 impact-bumper models (built 1974-1989), sealing and cushioning the energy-absorbing bumper assembly while ensuring the correct aesthetic appearance when the impact tubes are removed or replaced.

Fits:
Porsche 911 1974 - 1989
Porsche 930 1976 - 1989

Diagram ref no 42 (front bumper) and 14 (rear bumper)

Constructed from high-quality rubber with correct hardness and ageing-resistant compound, the bellows restore proper fitment, eliminate flapping or sagging, maintain correct bumper tube alignment and preserve that factory-correct look of the early “G-series” 911 / 930 models.

• Function: These bellows serve to cushion and seal the bumper impact tubes, protect the chassis mount region from road debris and water ingress, provide correct mounting geometry and restore the original gap/flex behaviour of the bumper system.

While bellows may seem like minor rubber parts they play a crucial role:
• Worn or collapsed bellows can lead to loose or mis-aligned bumper tubes, which may damage paintwork or rubber finish around the mounting.
• Missing or deteriorated bellows allow dirt, water and debris into the impact-tube housing, accelerating corrosion and reduced structural integrity.
• Incorrect or absent seals can lead to visible gaps, poor bumper alignment and reduced impact-absorption performance.

Replacing all four at once ensures symmetrical bumper behaviour, restores correct fitment front and rear, and preserves the value and originality of your G-series 911 or 930.

When to replace:
• Original bellows appear cracked, hardened, sagging or distorted.
• You’re replacing bumper tubes, painting bodywork or restoring the front/rear sections.
• The vehicle is being prepared for show, sale or concours and requires correct rubber components.
• You’re experiencing loose bumper feel, water ingress in the mount region or visible rubber deterioration.
