What This Product Does:
- The reinforcement bar tube sits behind the rear bumper cover and acts as a structural “crash beam” or impact absorber. Its function is to distribute and absorb energy in the event of a rear impact, protecting the bumper cover, rear bodywork and chassis mounting points.
- It also provides structural support to the rear bumper assembly, helping maintain correct alignment and mount positioning of the bumper. For older cars, correct mount and alignment helps reduce looseness or mis-fit in the rear bumper.
- By being in good condition (straight, undamaged, properly mounted), it contributes to the integrity of the rear body shell, ensuring panel fitment, bumper alignment, and the proper load path in case of a collision.
- Essentially: it’s a safety and structure component — not just cosmetic — and is especially important in restorations, body repairs, and when ensuring the car meets structural integrity standards.
Signs Of Wear / Damage & When To Replace:
- The rear bumper appears mis-aligned, sagging, or sits unevenly relative to body panels — indicating the support tube might be bent or mounting points damaged.
- Visible damage: the tube is bent, dented, corroded severely, showing cracks or fatigue — this compromises its ability to absorb impact and maintain structure.
- After a rear-end collision or bumper impact, even if cosmetic damage seems minimal — the reinforcement tube may have absorbed energy or deformed; replacing it restores safety and alignment.
- Rust or corrosion causing weakening of the tube or its mounting brackets—on cars approaching decades of use (964 is now over 30 years old) this is a valid concern.
- Increased looseness of the rear bumper or rear body shell components, or rattles/loose mounts behind the bumper — the reinforcement tube might not be holding the structure rigidly.
Why Replacement Matters:
- Safety and Crash Performance: Even if you never have a significant rear impact, the reinforcement tube is part of the safety system. A deformed or compromised tube will not perform as intended in an accident, risking more damage or injury.
- Panel Alignment & Fitment: For restoration or high-quality build work, ensuring the rear bumper and body panels mount correctly requires the reinforcement tube to be straight and correct.
- Resale & Condition: A 964 with proper structural components (including undamaged crash beams) is more desirable; replacing a worn/damaged tube helps maintain value.
- Repair Foundation: After any rear damage, replacing or straightening this tube provides a solid foundation before mounting bumper shells, diffusers or other external parts.
- Longevity: With age, even non-crash cars can have tubes that are weakened, corroded or mis-mounted; proactively replacing it ensures the structure remains sound for another several decades.

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.
Sold individually, two required per vehicle for a complete installation.
Fits:
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
