Diagram Ref No 7

Also known as a rear shock absorber dust cover, shock absorber protective boot or suspension damper bellow, this component is designed to protect the shock absorber piston rod and sealing area from dirt, dust, moisture and road contaminants.

The rear shock absorbers play an essential role in controlling suspension movement, maintaining ride stability and ensuring consistent vehicle handling. Their exposed piston rods and sealing surfaces must remain protected from abrasive particles and environmental contamination.

The shock absorber bellow provides a flexible protective covering that extends and compresses with normal suspension movement.

By shielding the damper's working surfaces, the bellow helps reduce the risk of contamination-related damage, premature seal deterioration and unwanted wear.

Manufactured to provide OE-style fitment, this replacement component is suitable for applicable rear suspension assemblies fitted to Porsche 993, 996 and 997 models.

Over time, original shock absorber bellows can become cracked, brittle, torn or dislodged due to ageing, repeated suspension movement, road debris and environmental exposure.

A damaged or missing bellow can leave the shock absorber piston rod vulnerable to dirt, moisture and abrasive contamination, potentially accelerating deterioration of the damper seals.

The OE MATCH replacement offers a practical solution for restoring the original suspension protection arrangement without replacing an otherwise serviceable shock absorber.

Ideal for rear suspension repairs, shock absorber replacement and comprehensive Porsche suspension refurbishment, this component helps preserve the condition and long-term reliability of the rear damping system.

What This Product Does:
The rear shock absorber bellow provides a flexible protective barrier around the exposed section of the shock absorber piston rod.

Its primary purpose is to prevent road contaminants from reaching the damper rod and associated seals while allowing the suspension to move through its normal operating range.

Its key functions include:

• Shock Absorber Protection: Helps protect the rear damper piston rod against exposure to dirt, dust and road debris.
• Moisture Protection: Reduces direct exposure of the shock absorber rod and seal area to rainwater and road spray.
• Dirt and Dust Prevention: Helps prevent abrasive particles from collecting around vulnerable damper surfaces.
• Piston Rod Protection: Shields the exposed rod surface from contamination that could contribute to scratches or damage.
• Seal Protection: Helps reduce the amount of dirt reaching the damper's sealing components.
• Reduced Premature Wear: Supports longer shock absorber service life by limiting contamination-related deterioration.
• Flexible Suspension Movement: Compresses and extends as the shock absorber moves during normal driving.
• Corrosion Risk Reduction: Helps limit environmental exposure around the protected damper components.
• Suspension Maintenance: Provides a replaceable protective component within the rear strut assembly.
• Original Suspension Configuration: Maintains the factory-style protective arrangement around the rear shock absorber.
• OE-Style Fitment: Provides a replacement for damaged or deteriorated original bellows.

Symptoms Of Wear Or Failure:
Rear shock absorber bellows experience constant movement as the suspension compresses and rebounds. Over time, age, temperature changes and environmental conditions can cause the material to deteriorate.

Common symptoms include:

1. Cracked or Split Bellow

Visible cracks or splits in the flexible material indicate deterioration and may allow contaminants to reach the shock absorber.

2. Torn Protective Material

Road debris, incorrect installation or repeated contact with surrounding components can tear the bellow.

A torn cover may no longer provide effective protection across the damper's full range of movement.

3. Hardened or Brittle Material

Ageing and environmental exposure can cause the bellow to lose flexibility.

This increases the risk of cracking when the suspension compresses and extends.

4. Missing Shock Absorber Bellow

An absent bellow leaves the damper piston rod and sealing area directly exposed to road contamination.

5. Loose or Dislodged Cover

A damaged or incorrectly fitted bellow may move away from its intended position, exposing vulnerable shock absorber surfaces.

6. Collapsed or Deformed Bellow

A distorted or permanently compressed cover may fail to extend correctly as the suspension moves.

7. Dirt Accumulation Around the Piston Rod

Visible dirt, grit or road debris on the exposed damper rod may indicate that the protective covering is damaged or missing.

8. Moisture Around the Damper Rod

A compromised bellow can allow additional moisture and road spray to reach the shock absorber.

9. Surface Corrosion on Exposed Components

Prolonged environmental exposure may contribute to corrosion on susceptible unprotected metal surfaces.

10. Scratches or Marks on the Piston Rod

Abrasive contamination can damage the smooth damper rod surface, potentially affecting the seal's service life.

11. Shock Absorber Oil Leakage

Oil around the damper body or piston rod may indicate a damaged internal seal.

A missing or deteriorated bellow can contribute to contamination-related seal wear, but replacing the bellow will not repair an existing oil leak.

12. Deterioration Identified During Suspension Servicing

A damaged bellow is commonly discovered when rear shock absorbers, suspension springs or related components are inspected or replaced.

Why Replacement Matters:

• Replacing a cracked, torn or missing rear shock absorber bellow is an important part of protecting the suspension damping system and reducing the risk of premature shock absorber deterioration.
• The Porsche 911 rear suspension is designed to maintain stable handling, ride comfort and controlled wheel movement across a range of driving conditions.
• The shock absorbers contribute to this performance by controlling suspension compression and rebound.
• A shock absorber contains precision internal components, and its piston rod must move smoothly through the damper's sealing arrangement.
• The protective bellow helps keep road contaminants away from these vulnerable surfaces.

This acts as a progressive load-bearing element, cushioning the suspension when the strut nears full compression. It helps prevent harsh bottoming-out, protecting both the strut and chassis from damage during aggressive driving or over bumps. These components maintain ride quality and handling performance, especially under heavy loading or spirited cornering, keeping the suspension linear and controlled. 

Common Issues & Considerations Wear or Deterioration: Over time, the rubber can compress, crack, or lose elasticity, diminishing its effectiveness. This can lead to harsher suspension impacts at full compression. Noise or Harsh Feedback: A worn or hardened bump stop can transmit noise or impacts through the cabin, particularly over rough roads or speed bumps. Sport vs. Standard Suspension: These parts are specific to Sport chassis models. Non-sport setups may not have the same bump stops or use different part numbers, so swapping or replacing must be done accordingly.

Required Quantity
Two washers are specified across the rear shock absorber and coil spring assemblies for the applicable chassis configurations.

What Is This Part?
This is the lower concave washer used within the rear shock absorber and coil spring assembly. Its dished shape provides a seating surface for the adjoining components, so its profile and fitted orientation matter when the assembly is rebuilt. It works alongside the damper, spring and associated seating hardware rather than providing damping itself. OE Match is a Porsche-focused replacement-parts brand; this washer should be selected against the vehicle's chassis equipment as well as its model and year.

What Does This Part Do?

• Provides a shaped seat: Forms the lower spring-disc interface within the applicable rear suspension assembly.
• Supports correct assembly: Works with the adjoining spring and damper hardware in their intended arrangement.
• Maintains the seating profile: Provides the concave contact surface required at this position.

Why Replace This Part?
Replacement may be appropriate if inspection finds corrosion, cracking, distortion or damage to the seating surface. A washer that has lost its intended shape may no longer sit correctly against the adjoining components, so it should be assessed when the rear spring and damper assembly is dismantled.

Renewing a damper does not automatically mean this washer must be replaced. Check its condition alongside the spring seats, mounts and other hardware, and replace any component that is damaged or unsuitable for reuse. Rear suspension noise should be traced to its cause rather than assumed to come from this washer.

When to Replace This Part?

• Visible deterioration: Significant corrosion, cracking or loss of material around the seating surface.
• Distorted profile: Bending, flattening or other damage that prevents correct seating.
• Damaged contact areas: Pronounced wear or fretting where the washer meets adjacent components.
• Incorrect or missing hardware: Inspection confirms that the lower washer is absent or the wrong version has been fitted.
• During suspension dismantling: Inspect the washer when access is available and replace it if its condition makes reuse unsuitable.

Where Is This Part Fitted?
Location: Within the rear shock absorber and coil spring assembly, at the lower concave washer or spring-disc position. Retain the correct component order and orientation when rebuilding the assembly.

Product Summary

• Product: Lower rear shock absorber concave washer / spring disc.
• Brand: OE Match.
• Part reference: 99733351300.

What This Product Does

The ring forms part of the rear damper mounting arrangement, supporting the correct location of the shock absorber and adjacent suspension components. It is suitable for replacement during rear damper, spring or mounting work where the original ring is worn, damaged or missing.

Functions

• Forms part of the rear shock absorber and coil-spring assembly
• Provides a seating and support point within the damper installation
• Helps maintain the intended position of the associated suspension components
• Allows ageing mounting hardware to be renewed during suspension servicing

Technical Details

• Brand: OE Match
• Reference number: 99733350400
• Installation position: Rear
• Diagram ref no 4

Symptoms of Fault

• Knocking or rattling from the rear suspension
• Movement around the rear damper mounting assembly
• Visible compression, cracking or deterioration of the original ring
• Noise continuing after damper replacement because old mounting parts were reused

Why Replacement Matters

Ageing rear shock absorber hardware can contribute to unwanted movement or suspension noise. Inspecting and renewing this ring while the damper assembly is dismantled can avoid reusing a deteriorated component and repeating the same labour later. Check the supporting mounts, bump stops, bellows, springs and fasteners at the same time.

FAQs

• How many are required?
  Two rings are required per car, with one used on each side of the rear suspension.
• Should both sides be replaced together?
  Replacing both sides is generally advisable where the existing components are of the same age and condition.
• What else should be inspected?
  Check the rear dampers, supporting mounts, springs, bump stops, protective bellows and mounting hardware while the assembly is accessible.
