Why Replacement Matters
Rear shock absorber mounts and fittings age with mileage, especially on cars that see mixed road conditions. As rubber and hardware deteriorate, noise, harshness and poor damper control can develop. Replacing worn rear mounts and fixings when renewing dampers, or when symptoms appear, helps maintain consistent suspension behaviour and can reduce the risk of repeat work caused by reusing tired hardware.
FAQs
- Q: Should these rear mounts be changed with new shocks?
A: They are often replaced when fitting new rear dampers, particularly if the existing mounts are original, noisy or show signs of wear. - Q: What commonly causes rear knocking noises?
A: Rear knocking can be caused by worn mounts, drop links or bushes; inspection of all related components is recommended. - Q: Any maintenance tip for rear suspension work?
A: Consider renewing bump stops, dust boots and key hardware at the same time to avoid repeating labour later.

Camber Plates/Strut Mounts - Under extreme conditions, such as road racing and autocross, negative camber is required to keep as much of the tire's contact patch on the road as possible. Stock suspension mounts will not allow you to achieve the necessary amount of negative camber required for this type of performance driving. Rennline's Sealed camber plates incorporate FK motorsports Teflon-lined spherical bearings and eliminate the indistinct feedback associated with factory rubber mounts. Why are Rennline's strut mounts the best ?
• Drastically increased bearing life due to the integrated factory GT3 weather seals.
• FK Motorsports Teflon-lined spherical bearings.
• Rigid bearing mount, not clipped in like some products available.
• Can be used with all factory and aftermarket struts, Including factory non adjustable units. Call for details.
• Fully rebuildable
• CNC machined 6061 anodized aluminum construction with stainless steel hardware.
• Available for front and rear.
• Drastically increased bearing life due to the integrated factory GT3 weather seals.

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 OE match kit consists of a suspension bump stop and dust cover designed to replicate the original Porsche factory components used on the 993 generation 911. Installed on the shock absorber shaft, these components work together to protect and extend the life of the suspension system.
SET OF 4 PARTS
Fits:

Porsche 993 1994 - 1998 (not RS)

The bump stop acts as a secondary spring, preventing the shock absorber from fully compressing under extreme loads, while the dust cover shields the piston rod from dirt, debris, and moisture. This combination ensures optimal suspension performance and longevity.
Manufactured to OE specifications, this kit is ideal for replacing worn or deteriorated original parts, especially during suspension overhauls or shock absorber replacement.
This kit protects the shock absorber from impact damage and contamination. The bump stop absorbs excessive compression forces, while the dust cover prevents dirt and debris from damaging the shock shaft, helping maintain smooth suspension operation.
Function
• Absorbs impact at full suspension compression (bump stop)
• Prevents shock absorber bottoming out under load
• Protects shock shaft from dirt, debris, and moisture (dust cover)
• Extends the lifespan of shock absorbers
• Maintains consistent suspension performance and ride quality
Over time, bump stops degrade, crumble, or lose elasticity, while dust covers can crack or split. This exposes the shock absorber to contamination and increases the risk of internal damage. Replacing these components helps protect the suspension system, maintain ride quality, and prevent premature shock failure.
When to replace
• Bump stop is cracked, brittle, or disintegrating
• Dust cover is split, missing, or damaged
• During shock absorber replacement
• Noticeable harsh bottoming-out or knocking noises
• Visible contamination on the shock shaft
