Rear shock absorber supporting top mounts and fittings for the Porsche 993 by OE Match, suitable for selected 993 models from 1994–1998.
What This Product DoesThese rear supporting top mounts and associated fittings locate the rear shock absorbers securely on the Porsche 993, helping the dampers operate correctly and reducing unwanted movement or noise at the rear axle.
Functions
- Secure the rear shock absorber to the body
- Support correct rear damper alignment
- Help control noise and vibration at the rear axle
- Assist in protecting the damper from undue stress
Symptoms of Fault
- Knocking or clunking noises from the rear over bumps
- Rattles from the rear suspension area
- Harsh impacts felt through the rear of the car
- Premature wear or damage to rear dampers
- Vague or unsettled feel from the rear of the vehicle
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.

These precision moulded rings sit between the rear shock absorber and its mounting point, ensuring a snug, vibration free fit. Over time, the original rubber rings can compress, harden or split, leading to unwanted movement or clunking noises from the suspension. Manufactured to OEM dimensions using high grade elastomer, this pair provides a simple, cost effective solution to maintain proper suspension alignment and comfort.

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

OEMatch Shock Absorber Parts — Control, Stability, Comfort
OEMatch shock absorber parts for Porsche models provide replacement components for the vehicle's damping system, chosen to suit model-specific requirements and repair procedures. Many owners search for genuine or OEM shock absorber parts; these are direct-fit alternatives designed to match the original form, fit and function.
Available Types
- Top mounts and bearing plates
- Bump stops and travel limiters
- Dust covers and bellows
- Seals and oil retention components
- Bushes and mounting hardware
Understanding OEMatch Shock Absorber Parts
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original shock absorber parts. OE (Original Equipment) refers to parts matching original specifications for the shock absorber parts and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM shock absorber parts engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. These rear suspension items include the mounts, seals and protective components that work with the damper body to control vehicle motion and preserve handling characteristics; correct identification and matching to the vehicle are important for reliable reinstatement of ride and control.
Benefits Include
- Restores damping control and ride comfort where worn parts have degraded performance
- Reduces noise and harshness caused by failing mounts or damaged seals
- Helps preserve tyre contact and steering consistency under load
Why Shock Absorber Parts Wear and Fail
- Age and fatigue from repeated compression and extension of seals and mounts
- Contamination or physical damage from road debris, broken dust covers or leaking oil
- Corrosion and loss of lubrication allowing bearings and mounts to seize or degrade
The Importance of Replacing with OEMatch Shock Absorber Parts
Replacing worn or damaged shock absorber parts helps maintain the damping system's intended performance, which supports vehicle stability, braking balance and even tyre wear. Choosing matching replacement parts ensures correct mounting interfaces and sealing to protect the damper; when maintenance affects suspension geometry or hidden fastenings, use correct procedures and parts to avoid introducing handling faults.
Advantages
- Designed for direct compatibility with Porsche model references to simplify identification and fitting
- A range of replacement components that allow targeted repairs without replacing complete dampers where not required
- Catalogued cross-references and part descriptions to aid correct selection for specific model years
Support & Advice
These items affect safety-critical systems. Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and new fasteners where specified.
