Product Information

Rear bumper bracket tube
This OE Match Rear Bumper Bracket Tube (also known as a bumper impact tube) is a structural mounting component designed for classic Porsche 911 models. It supports and positions the rear bumper assembly on the vehicle.

Porsche 911 1974 - 1989
Porsche 930 3.0L / 3.3L 1975 - 1989

Diagram ref no 27

The bumper bracket tube secures the rear bumper to the vehicle body while providing a degree of shock absorption in low-speed impacts. It ensures the bumper remains correctly aligned and properly spaced from the chassis.

Without this component, the bumper cannot be securely mounted, affecting both safety and vehicle appearance.

Function
• Supports and mounts the rear bumper to the chassis
• Maintains correct bumper alignment and spacing
• Absorbs minor impact forces
• Provides structural integrity to the bumper assembly

This component is essential for both functional safety and maintaining the original look of the vehicle.

Over time, bumper tubes can corrode, bend, or weaken due to age, environmental exposure, or minor impacts. Damaged tubes can lead to misaligned bumpers, poor fitment, and reduced structural support. Replacing worn or damaged bumper tubes ensures proper bumper positioning, restores original appearance, and maintains safety standards - especially important for restoration projects and classic Porsche maintenance.

When to replace:
• Visible corrosion or rust on the tube
• Bent or deformed bumper mounting points
• Loose or misaligned rear bumper
• During restoration, repainting, or bumper removal
• After minor rear-end impacts
