Check fitment for your specific vehicle (model, year, engine) before ordering.
What This Product Does
A strut bellows provides a flexible protective covering around the exposed damper rod, accommodating suspension movement while limiting contamination. It is a protective component rather than a shock absorber, mounting bearing or bump stop.
Functions
- Shields the damper rod against road dirt and debris.
- Maintains protective coverage as the suspension moves.
Technical Details
- Supplied quantity: two bellows.
- Position specified for this set: Front.
- Component reference: 99634350901.
- Brand: OE Match.
- GT3 restriction: use only with shock absorber 997.333.051.99; the supplied diagram records the application note as 10-.
Symptoms of Fault
- Visible cracks, splits or missing sections in an existing cover.
- A displaced bellows leaving the damper rod exposed.
- Rattling associated with a loose or damaged dust cover; inspect adjacent hardware before attributing the noise to the bellows.
Why Replacement Matters
Renewing damaged bellows restores the protective covering around the damper rod. During damper servicing, inspect both covers alongside the mounts, bearings and bump stops rather than automatically reusing deteriorated components. A new cover will not correct leakage or internal damper wear.
FAQs
Are two bellows included?
Yes, this set contains two protective bellows.
Should these be checked when changing dampers?
Yes. Examine the covers for damage and confirm that they fit the replacement dampers.
Does the GT3 application have a restriction?
Yes. The supplied diagram specifies use only together with shock absorber 997.333.051.99.

• Direct fit replacement, matching OEM dimensions, mounting points, and bearing or mounting hardware.
• Location: Front axle, upper shock/strut assembly mount, fits left or right shock absorbers.
• Designed to maintain proper strut angle, absorb vibration, and ensure geometry and ride comfort.
The front strut mount endures high loads, road vibration and pivoting motion of the suspension. A worn or failed mount can lead to clunking noises, poor alignment, erratic tyre wear or degraded ride comfort.
Replacing with a new replacement unit restores the correct mount geometry, the proper bearing or bushing action, and helps maintain the precise handling and comfort expected from the Porsche 993 platform.

It provides a cushioning effect when the suspension approaches the end of its travel, helping protect the shock absorber and surrounding components from damage.
What Does It Do?
The bump stop cushions the suspension during heavy compression, reducing the risk of the shock absorber reaching the end of its travel abruptly.
Why Does It Fail?
Common causes include:
- Age-related material deterioration
- Repeated suspension compression
- Exposure to road dirt and moisture
- Cracking or splitting
- Damage during shock absorber removal
When Should It Be Replaced?
Replace if the bump stop is cracked, crumbling, compressed or missing.
Inspection is recommended when replacing shock absorbers, springs or other suspension components.
Checks & Diagnosis
Inspect the bump stop for visible deterioration and check the shock absorber for leaks or damage.
Harsh impacts over bumps or excessive suspension bottoming may indicate worn suspension components requiring investigation.
Key Features
- OE Match replacement shock absorber bump stop
- Suitable for applicable Porsche 964 and 993 models
- Cushions excessive suspension compression
- Helps protect shock absorbers from damage
- Ideal for suspension servicing and restoration
Porsche 964 & 993 Shock Absorber Bump Stops and Suspension Parts
Shock absorber bump stops are important components of the Porsche 964 and 993 suspension systems, helping control suspension travel and protect shock absorbers during heavy compression.
Replacing deteriorated bump stops helps maintain suspension protection and supports reliable operation.
