Bilstein Replacement for the Original Spec

Porsche 997 C2 / C2S - For vehicles with PASM, For vehicles with electronic suspension control
B4 High Quality direct replacement shock absorbers constructed and finished to Bilstein's high standards often far and above what the car was originally supplied with. They can actually be a performance improvement if replacing plain, none gas charged, oil filled dampers. They dramatically reduce cavitation / oil foaming, thus give for more stable damping forces when driven 'spiritedly'. Some surprising cars come with plain oil filled dampers.
Key Features:
- Twin Tube Damper
- Gas pressurized
- OE damping forces

This product supersedes Porsche's old part numbers:
99633104506, 99633104508, 99633104510, 99633104512, 99733104504 , 99633104512
What this product does:
• Provides a secure connection between the chassis and wheel hub
• Maintains wheel alignment for safe, predictable handling
• Absorbs suspension forces while keeping steering precise
Over time, control arms can bend, wear, or develop excessive play in the bushings and ball joints. This can cause uneven tire wear, knocking noises, wheel alignment issues, and a noticeable loss of steering precision. Replacement will restore the correct wheel alignment and suspension stability for which your Porsche was designed.

These replacement shock absorbers are compatible with PASM-equipped cars and include built-in cancellation resistors to eliminate dashboard errors. They effectively bypass the Active Suspension Management system, allowing the vehicle to function as though it has standard suspension installed.
Set includes:
2 × 99734304524 – OE Match Front shock absorbers (left + right)
2 × 99733305332 – OE Match Rear shock absorbers (left + right)

- These shock absorbers are not PASM dampers and do not offer PASM-adjustable damping.
- They are designed as standard replacement units with built-in electronics to cancel PASM fault warnings.
- For correct functionality and proper vehicle handling, they must be installed as a full set of four (2 × front shock absorbers + 2 × rear shock absorbers)
- Mixing PASM units with OEMatch replacement units is not permitted and may result in suspension imbalance or fault messages.
Over time, shock absorbers lose their ability to control movement, leading to a less stable, bouncier and less predictable car. Replacing all four dampers at once ensures perfectly matched suspension behavior, consistent ride comfort and proper chassis balance across front and rear.
When to Replace:
• Noticeable bounce, float or instability
• Leaking shock oil on any corner
• Front-end dive under braking or rear squat under acceleration
• Rough ride quality, vibration or knocking noises
• Uneven tyre wear or alignment issues
• Full suspension refresh on higher-mileage 997 models

- These shock absorbers are not PASM dampers and do not offer PASM-adjustable damping.
- They are designed as standard replacement units with built-in electronics to cancel PASM fault warnings.

- Mixing PASM units with OEMatch replacement units is not permitted and may result in suspension imbalance or fault messages.
Over time, front shocks lose their damping strength, which can make the car feel less responsive, less stable and less comfortable. Worn shocks can increase braking distances, reduce cornering grip and lead to uneven tyre wear. Replacing them restores proper suspension control, steering sharpness and the confident handling the 997 chassis is known for.
When to Replace:
• Noticeable nose-dive during braking
• Excessive bounce, vibration or front-end instability
• Leaking shock oil or visible damage
• Steering feels vague or less precise than usual
• Uneven or accelerated front tyre wear
• Performing a full suspension refresh for improved handling consistency

Porsche Suspension & Axle Parts
Porsche suspension systems are engineered with precision to deliver sharp handling, ride comfort, and maximum performance. Whether on the road or track, your Porsche relies on a finely tuned suspension and axle setup to keep you in control. When components wear out, the ride becomes rough, handling suffers, and safety can be compromised.
At Design911, we supply a full range of suspension and axle parts for classic and modern Porsche models — from shock absorbers and coil springs to control arms and ball joints - helping you maintain your car’s legendary driving dynamics.
Signs of Worn Shocks or Struts
Shock absorbers and struts are essential for keeping your
Porsche stable over bumps and through corners. Some signs they may need
replacement include:
- Excessive
Bouncing – car continues to bounce after hitting bumps
- Poor
Cornering Stability – leaning hard into corners, reduced grip
- Fluid
Leaks – damp or oily patches on shocks/struts
- Uneven Tyre Wear – poor damping leads to increased tyre wear
If left unchecked, worn shocks or struts not only reduce ride comfort but can also compromise safety.
Common Porsche Suspension Issues
Different Porsche models can face specific
suspension-related faults. The most frequent include:
- Lower
Track Control Arm Bushings - Failure
causes squeaking noises, uneven tyre wear, and eventually knocking sounds
over rough roads.
- Broken
Coil Springs - Seen
in models such as the Porsche Boxster. Symptoms include groaning noises
when steering and clicking or knocking over bumpy surfaces.
- Leaking
or Worn Shock Absorbers - Identified
by damp, oily residue on the shock body. This is one of the most common
suspension failures over time.
- Ball Joint Wear - Worn joints reduce steering precision and can lead to loss of control if ignored.
Fortunately, most of these issues can be resolved by simply replacing the affected parts with OEM or high-quality aftermarket components.
