Supporting rear suspension top mounts, SET OF 2
Refresh rear end precision and ride comfort with this OE Match pair of rear suspension top mounts for Porsche 996. These mounts use premium rubber and a high-quality bearing interface to control strut movement, cut noise/harshness, and maintain correct geometry under load. Ideal when replacing rear dampers or chasing knocks, creaks, tramlining or uneven tyre wear. Supplied as a matched left/right pair for consistent handling.

Fits:
Porsche 996 C2 / C4 / C4S 1998 - 2005
Porsche 996 Turbo / GT2 2001 - 2005
Porsche 996 GT3 MKI

Diagram ref no 2

Manufactured using high-quality forged aluminium and fitted with durable rubber bushes and ball joints, they ensure excellent suspension response, ride comfort, and long-term reliability. Ideal for eliminating unwanted steering vibration, uneven tyre wear, or suspension noise.

• Position on Vehicle: Rear suspension – both upper shock absorber/strut mount positions.
• Cross-Reference / Alternative Numbers: 2 × 996 333 059 03 (each mounted left & right)
• Applications: Ideal for full rear suspension overhaul where both mounts are being replaced for uniform performance.

Replacing both sides together avoids mismatched performance, where one side’s mount is new and the other is still worn — leading to inconsistent handling, uneven ride feel and asymmetric noise. A full set ensures true rear-suspension balance, restored comfort and dependable stability.

When to replace both:
• One side already shows wear – replace both to maintain symmetry.
• Rear shock/strut replacement performed on both sides – pair with mounts for full service.
• High-mileage vehicle where both mounts are likely nearing end-of-life.
• You want consistent ride and handling across both rear corners.
• To avoid replacing the second side shortly after the first, saving downtime and labour.

Rear shock mount kit.

Fits:
Porsche 996 1999-04

These shock mounts use high strength hardened steel spherical bearings and are direct replacements for the factory mounts. The Teflon lined spherical bearings used in our kit are maintenance-free and require no supplemental lubrication. Included seals prevent contamination from water or grime, thus extending bearing life.

Porsche used spherical bearings on the 997 GT3 and Cup Cars. We went one step further and added larger bearings and weather-seals to ensure longevity.

Fully Weather Sealed

We've designed in weather seals to keep dirt out and extend product life. This is the only shock mount suitable for street or extended track use. Dirt and water contaminate ordinary products and accelerate wear.

Improved Shock / Coilover Performance

The spherical bearings pivot freely and eliminate the deflection that is inherent with the factory rubber bushings. This is important because:

The factory rubber acts as a spring in series with the shock. This rubber spring-action is completely un-damped and reduces the shocks ability to control the tire contact patch. The spherical bearing allows the damper to do its job and control the contact patch.

These will work with stock springs and coilovers.

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.
