A front bumper impact/mount tube that bolts between the body and the bumper assembly, supporting the bumper and helping locate it at the correct distance from the bodywork. It fits either left or right side; two are required per car.
SET OF 2
Fits:
Porsche 911 1974 - 1989
Porsche 930 3.0L, 3.3L 1974 - 1989
Diagram ref no 23, 13, 17, 16, 18, 19, 21/22 , 20
This metal bracket tube supports and locates the front bumper at the correct distance from the body, forming part of the impact-bumper mounting system. It helps maintain bumper alignment, panel gaps, and structural stability under normal driving and minor impacts. By replacing damaged or corroded tubes, it restores proper bumper fitment and ensures the assembly is safely and securely mounted.
Over the years, the original tubes can suffer from corrosion, accident damage, or bending from improper towing or jacking. A weakened or distorted tube can cause poor bumper alignment, uneven gaps, rattles, or a loose-feeling bumper. In more serious cases, it may compromise the way the bumper mounts in a minor impact. Replacing it with a correctly made tube restores structural confidence and the clean, straight look of the front end.
Consider replacing the front bumper tube if:
• The existing tube is rusted, bent, or dented
• The front bumper sits crooked, too close, or too far from the body
• The car has had front-end damage or a bumper impact
• You’re carrying out a full restoration or repaint and want correct fitment

Why Replacement Matters
Bumper repairs following an impact or restoration work provide an opportunity to inspect the smaller assembly components. Confirm that the base itself requires renewal rather than assuming that poor alignment originates here; surrounding brackets, fixings and bumper components should be assessed separately.
