Shock Absorber Front, SET OF 2. Porsche 997.1 / 997.2 C4 / C4S with PASM 2005-12

Shock Absorber Front, SET OF 2 (Left and right).
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.

Kit includes:
 1 × 99734304741 - OE Match Front Left PASM Shock
 1 × 99734304841 - OE Match Front Right PASM Shock


Fits:
Replacement for Car with PASM Electronic Damper Control (option code: 475)
Porsche 997.1 Carrera 4 / Carrera 4S  2005 - 2008 Coupe / Cabrio
Porsche 997.2 Carrera 4 / Carrera 4S  2009 - 2012 Coupe / Cabrio

• 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.       

Diagram ref no 1

Over time, PASM front shock absorbers lose their damping accuracy, which affects both comfort and handling. Worn dampers can cause inconsistent ride quality, reduced steering precision and poor stability over bumps or under braking. Replacing them restores full PASM functionality, ensuring the suspension reacts correctly in all modes and returns the 911’s signature balanced, confident road feel.

When to Replace:
• PASM fault messages appear
• Leaking hydraulic fluid from either damper
• Front suspension feels harsh, bouncy or unstable
• Noticeable decline in steering precision
• Completing a suspension refresh for optimal handling
