This bellow fits where the bumper's impact-absorbing tube meets the chassis mount. It replicates the original Porsche's form and function: the correct corrugated rubber profile, factory-style mounting holes, accurate dimensions, and the correct spacing between mounting tabs.

• Position: Front bumper, left/right side impact-tube bellow (part number 91179950513/ 91179950514) – between bumper tube and chassis mount bracket.
• Function: Provides sealed flexible coupling between front bumper impact tube and chassis mount, absorbs minor movement/shock, prevents debris ingress, maintains correct bumper mounting geometry and fitment.
• Material & Construction: Corrugated rubber bellow manufactured to exact original Porsche profile, with correct mounting flange and bolt-hole spacing, designed for direct-fit replacement.
• Applications: Ideal when the original bellow is cracked, collapsed, missing, sagging, or has deteriorated rubber and no longer provides correct sealing or alignment.
Although often overlooked, the impact-bumper bellows play an important role in the structural and visual integrity of the bumper system. If the bellows are missing or worn, you may face:
• Rearranged or sagging bumper tube alignment
• Water or road-salt ingress into mounting areas, promoting corrosion
• Noticeable gaps or mis-alignment at bumper ends, affecting appearance
• Excess vibration or looser bumper feel due to degraded rubber
Replacing the bellow restores correct mounting geometry, prevents damage to the chassis or bumper tube, restores the original look and seals out elements.
When to replace:
• The rubber is cracked, faded, sagged or missing
• The bumper tube shows signs of corrosion or mis-alignment at the joint
• During bodywork, restoration, bumper tube replacement, or mount servicing
• You want to ensure authentic trim and correct condition for your classic Porsche
