Rear shock absorber, for cars with PASM electronic damper control (option code: 475)
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.
It is always recommended to replace shock absorbers in pairsSET OF 2, Fits left and right side

  • 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.

 
Rear shocks wear out over time due to use, heat, and internal component fatigue. Worn dampers lose damping efficiency and can lead to:

 Harsh, unstable ride with excessive bouncing over bumps
 Degraded handling stability, especially under cornering or heavy braking
 Reduced tyre contact and increased tyre wear
 Less predictable rear-end behavior and reduced driving confidence

You should consider replacing rear shocks if:
  The ride has become noticeably harsh or unsettled over bumps and uneven roads
  You feel rear-end instability, sway, or reduced grip under braking or cornering
  The rear suspension shows uneven behavior or the struts are old/mileage is high
   You're performing rear suspension maintenance, upgrades, or full refresh
   You want to restore factory-correct handling and comfort

About OE Match with PASM

Porsche Rear Shock Absorbers for PASM | Design911 Adaptive Suspension Components for Ride Comfort & Precision Handling

Rear shock absorbers for Porsche Active Suspension Management (PASM) are sophisticated components that combine hydraulic damping with electronic control for adaptive performance. By automatically adjusting damping levels based on road conditions, speed, and driving mode, PASM rear shocks deliver exceptional comfort and agility — ensuring your Porsche maintains perfect composure and balance.

At Design911, we offer a comprehensive range of PASM rear shock absorbers, precision-engineered to meet the highest performance standards. Each unit is built using advanced materials, durable seals, and electronic actuators for consistent responsiveness. Ideal for servicing, suspension restoration, or performance upgrades, these components ensure your Porsche’s adaptive suspension continues to deliver maximum stability, traction, and control.

What Do Rear PASM Shock Absorbers Do?

Rear PASM shock absorbers form part of Porsche’s electronically controlled adaptive suspension system, automatically adjusting damping force in real time to maintain balance and ride comfort.

Core Functions:
• Electronically adjust damping stiffness for comfort or sport modes.
• Maintain rear-end stability under acceleration, braking, and cornering.
• Reduce vibration, pitch, and roll for smoother ride quality.
• Improve traction and control in variable road conditions.
• Work seamlessly with Porsche’s electronic control modules for precision handling.

In optimal condition, PASM rear shocks ensure the perfect blend of agility and comfort that defines Porsche’s suspension engineering.

Why Do Rear PASM Shock Absorbers Fail or Degrade?

Rear adaptive dampers operate under high pressure and constant motion, leading to gradual wear over time — particularly in performance or high-mileage vehicles.

Common Causes of Failure Include:
• Internal hydraulic fluid leaks reducing damping effectiveness.
• Electronic actuator or solenoid malfunction.
• Corrosion or contamination of electrical connectors.
• Seal deterioration from heat or moisture exposure.
• Sensor or control module communication faults.

When PASM shock absorbers begin to fail, drivers may experience harsh ride quality, warning lights, or reduced handling precision — clear indicators that inspection or replacement is necessary.

Why Replace or Upgrade Your Porsche Rear PASM Shock Absorbers?

Replacing worn or faulty adaptive dampers restores full PASM functionality and ensures your Porsche’s suspension delivers comfort and control as designed. Performance-tuned replacements can also enhance handling response and system reliability.

Key Benefits:
• Restores smooth ride quality and adaptive damping accuracy.
• Improves handling precision, traction, and rear-end stability.
• Eliminates suspension faults and uneven ride response.
• Engineered from corrosion-resistant, high-strength materials.
• Fits Porsche 911, Panamera, Cayenne, and Macan models with PASM.
• Perfect for adaptive suspension repairs, restorations, or upgrades.

Design911’s Porsche PASM rear shock absorbers combine engineering excellence with durability — ensuring your Porsche remains refined, balanced, and dynamic across all driving conditions.

Highlights

• Premium Porsche PASM adaptive rear shock absorbers.
• Precision-calibrated for comfort and sport damping modes.
• Restores performance, ride comfort, and suspension balance.
• Compatible with Porsche Active Suspension Management systems.
• High-quality materials for long-term reliability.
