What This Product Does
The damper restrains repeated spring movement after the rear wheels encounter an uneven surface. Working alongside the springs and mounts, it moderates suspension oscillation rather than carrying out the spring's supporting role.
Functions
- Controls rear spring oscillation.
- Limits repeated bouncing after road disturbances.
- Regulates suspension movement as wheel loads change.
Technical Details
- Part reference: 98733305128.
- Additional supplied references: 98733305116 and 98733305122.
- Installation position: rear, suitable for either side.
- Chassis application: PR:029, standard chassis.
- The supplied Boxster and Cayman diagrams record BILSTEIN against reference 98733305128.
Symptoms of Fault
- Repeated rear bouncing after bumps.
- A floating or unsettled sensation from the rear suspension.
- Visible fluid leakage around the damper.
- Knocks when crossing uneven surfaces.
- Irregular rear tyre wear.
These signs can also arise from worn mounts, bushes or other suspension components. Inspect the complete assembly before attributing a noise or handling change to the shock absorber.
Why Replacement Matters
A leaking or internally worn damper may no longer control suspension movement consistently. Renewal addresses this wear while retaining the specified standard-chassis application. Inspect the rear mounts, bushes, springs and protective components during the repair, and replace any associated items found to be damaged.
FAQs
Should both rear dampers be renewed together?
Replace rear dampers as a matched pair to avoid combining differently worn units. Two individually supplied absorbers are required for the rear axle.
Must the mounts also be changed?
Inspect them during removal. Wear, damage or noise may justify renewal, but replacement should follow their condition.
Is an alignment check needed?
Have the suspension geometry checked after the work where the installation procedure or disturbed components require it.

Porsche Standard Rear Shock Absorbers | Design911 Suspension Components for Stability, Comfort & Ride Precision
Standard rear shock absorbers are essential to your Porsche’s suspension system, working in harmony with springs and suspension mounts to control movement, reduce vibration, and maintain optimal ride height. They ensure that the rear wheels stay planted on the road, providing consistent grip, comfort, and balance during acceleration, cornering, and braking. Quality dampers are key to achieving Porsche’s trademark driving feel — precise, composed, and confidence-inspiring.
At Design911, we supply a premium range of standard rear shock absorbers, engineered for long-lasting durability, performance, and fitment accuracy. Using high-quality materials and advanced damping technology, these components deliver smooth, controlled suspension response. Whether you’re performing routine servicing, full restoration, or handling upgrades, our rear shocks ensure your Porsche maintains its signature ride comfort and performance precision.
What Do Standard Rear Shock Absorbers Do?
Rear shock absorbers regulate how your suspension reacts to road surfaces, ensuring consistent damping and stability across all driving conditions.
Core Functions:
• Dampen spring oscillations for a smooth, controlled ride.
• Maintain rear axle alignment and tyre contact with the road.
• Reduce vibration, bounce, and body roll during acceleration.
• Improve handling balance and braking performance.
• Protect other suspension components from premature wear.
Well-maintained shock absorbers are vital to maintaining stability, especially in high-performance or high-speed driving scenarios.
Why Do Rear Shock Absorbers Fail or Degrade?
Rear shocks are under constant stress and exposed to dirt, heat, and moisture — all of which gradually cause wear and performance loss.
Common Causes of Failure Include:
• Leaking hydraulic fluid reducing damping efficiency.
• Corroded shock absorber bodies or piston rods.
• Internal valve wear leading to uneven damping.
• Seal degradation due to age or contamination.
• Damage from rough roads or overloading.
When rear shock absorbers fail, symptoms include excessive bouncing, poor handling, uneven tyre wear, and rear-end instability — all indicators that replacement is needed for safety and ride quality.
Why Replace or Upgrade Your Porsche Rear Shock Absorbers?
Replacing worn or leaking rear shocks restores suspension comfort, control, and safety. Upgraded or performance-spec units enhance stability, feedback, and ride comfort for both spirited driving and everyday use.
Key Benefits:
• Restores smooth damping and balanced suspension performance.
• Improves traction, braking control, and handling response.
• Reduces noise, vibration, and harshness.
• Manufactured from high-strength, corrosion-resistant materials.
• Fits Porsche 911, 944, 968, Boxster, Cayman, Panamera, Cayenne, and Macan
models.
• Ideal for maintenance, restoration, or road-handling upgrades.
Design911’s Porsche standard rear shock absorbers deliver outstanding quality and reliability — helping your Porsche perform and ride exactly as intended, mile after mile.
