OE Match with PASM
By OE Match
- Porsche 991.1 Turbo 3.8L (520 Bhp) 2014-16
- Porsche 991.1 Turbo S 3.8L (560 Bhp) 2014-16
This OE Match full suspension package provides all four replacement shock absorbers for PASM-equipped cars, featuring built-in cancellation resistors to prevent dashboard errors. Replacement for adaptive damping system on Porsche 991.1 Turbo / Turbo S (2014–2016), Not suitable for GT2 models.
The kit includes two front replacement PASM shocks (OE ref no: 991343045A5) and two rear replacement PASM shocks (OE ref no: 99133305326) 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.
Fits:
Porsche 991.1 Turbo / Turbo S 2014 - 2016
Replacement for cars with option codes:
475 - "PASM" Electronic Damper Control
352 - Electronic Damper Control For PASM And PDCC
Diagram ref no 1
- 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.
Each damper is manufactured to be a direct-fit replacement shocks for PASM vehicles, complete with integrated cancellation resistors so you can upgrade with zero dashboard errors or warning lights, ensuring seamless communication with the PASM control module.
This set is ideal for high-mileage cars, leaking or weakened PASM dampers, or anyone seeking to restore the driving precision, comfort, and stability of the 991 Turbo platform.
As PASM dampers wear, internal valves weaken, seals leak and electronic reaction time slows - reducing the system’s ability to adjust damping. This results in instability, harsh ride quality, reduced grip and unpredictable handling. Replacing all four shocks direct-fit replacement shocks for PASM vehicles, complete with integrated cancellation resistors so you can upgrade with zero dashboard errors or warning lights.
When to replace:
• PASM warning messages or inconsistent adaptive damping
• Excessive body movement, squat, dive or rolling
• Harsh, bouncy or unstable ride on bumps
• Fluid leakage from any shock absorber
• Rear instability or poor steering precision
• Uneven or accelerated tyre wear
• High-mileage suspension (>60k miles) or full chassis refresh

OEMatch PASM front shock absorbers — Control, Stability, Comfort
OEMatch PASM front shock absorbers for Porsche models are replacement adaptive dampers prepared for Porsche applications. They restore the variable damping behaviour of Porsche Active Suspension Management, helping to retain ride comfort and handling balance across road conditions. This page summarises types, common faults and the practical benefits of replacing worn PASM dampers.
Available Types
- PASM front shock absorbers — replacement adaptive dampers for standard systems
- Reconditioned PASM dampers where specified by application
Understanding OEMatch PASM front shock absorbers
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original PASM suspension.
OE (Original Equipment) refers to parts matching original specifications for the PASM suspension and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM PASM suspension engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
PASM front shock absorbers combine electronic control with hydraulic damping to vary stiffness according to driving mode, vehicle load and road surface. The unit comprises a hydraulic damper with an electronic actuator that adjusts damping in real time, working with sensors and the vehicle control unit to adapt ride and handling. Replacing failed units restores the adaptive response and keeps chassis dynamics predictable.
Benefits Include
- Restores adjustable damping to preserve ride comfort and handling balance
- Reduces body roll, pitch and dive under dynamic loads
- Helps maintain steering precision and chassis stability
Why PASM front shock absorbers Wear and Fail
- Hydraulic fluid leaks that reduce damping effectiveness
- Electronic actuator, solenoid or wiring faults that limit adjustment
- Corrosion or damaged electrical connectors impairing sensor signals
- Internal seal wear or piston damage from long-term use or contamination
The Importance of Replacing with OEMatch PASM front shock absorbers
Replacing worn or leaking PASM dampers restores the adaptive suspension’s ability to balance comfort and performance. OEMatch supplies a wide selection of Porsche-related parts, including thousands of part numbers and extensive cross-references, intended to help maintain and repair vehicles across generations. Choosing suitable replacement dampers supports safe, predictable handling and reduces the risk of secondary chassis wear.
Advantages
- Direct-fit replacements engineered to match original dimensions and tolerances
- Corrosion-resistant finishes and high-strength materials for longevity
- Options for maintenance, restoration or upgrade applications prepared for Porsche models
