These replacement FRONT 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 OF 2 - fits left and right (shock absorbers should only be replaced in pairs.
Fits:
Porsche 991 GT3 / GT3 RS / Speedster
Replacement For cars with Option Codes
474 - Front axle lift function
475 - PASM electronic damper control
- 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.

- Porsche 957 Cayenne S / GTS 4.8L 2007-10
- Porsche 957 Cayenne Turbo / Turbo S 4.8L 2007-10
Each damper duplicates the original’s damping rate, mounting geometry, and mechanical tolerances to deliver predictable ride quality, handling performance, and suspension comfort. Because vehicles have left- and right-hand dampers, ensure correct side when ordering; ideally replace in pairs for balanced suspension behaviour.

This shock absorber smooths out bumps, potholes, and road imperfections to provide a more controlled and comfortable ride. It helps keep the front suspension stable during braking, cornering, and acceleration, supporting predictable steering and confident road-holding. By reducing unwanted oscillation, rebound, and vibration, it prevents instability and restores proper suspension performance when the original damper has become worn or ineffective.
Over time, shock absorbers lose their effectiveness through internal wear, fluid leaks, or weakened valving, which leads to a harsher ride and reduced suspension control. A worn damper allows excessive movement, causing instability, longer braking distances, and uneven tyre wear. Replacing it with a fresh OE-match unit restores proper damping, improves handling confidence, and helps maintain overall driving safety and comfort.
You should fit a new shock absorber if:
• The ride has become bouncy, unsettled or harsh over uneven surfaces
• Handling feels loose or unstable, especially at speed or under load
• The vehicle exhibits uneven tyre wear, or suspension components show stress
• Shock absorber shows leaks, damage or reduced damping performance
• You are refreshing or upgrading the suspension for improved comfort or safety
