What This Product Does
These rear lid gas struts support the Cayman tailgate, controlling its lifting and closing motion so the lid can be opened and held in position during everyday use or access to the luggage area.

Functions

  • Support the rear tailgate when open
  • Control the lifting and closing speed of the lid
  • Help prevent the lid from dropping unexpectedly
  • Assist with smooth, consistent tailgate operation


Symptoms of Fault

  • Rear lid feels heavy or difficult to lift
  • Tailgate drops or will not stay fully open
  • Visible oil mist or leakage on the damper shaft
  • Creaking or knocking noises when opening or closing the lid


Why Replacement Matters

Worn rear lid dampers can allow the Cayman tailgate to drop or close unpredictably and may make the lid awkward to raise. Replacing tired dampers restores controlled movement of the rear lid, supports routine access to the luggage area, and helps maintain correct operation of the tailgate assembly.

The Genuine Porsche Rear Lid Damper (Part Number: 98151255107) is an original equipment gas-filled support strut designed for Porsche Cayman models, specifically for vehicles without a rear window wiper (Option Code: 426). Also known as a rear tailgate gas strut or rear hatch support, this component helps lift and securely support the rear lid when opened, providing smooth and controlled operation.

Manufactured to Porsche's original specifications, the damper offers precise fitment, reliable lifting assistance and long-lasting performance. It is an ideal replacement for worn or weakened original gas struts, restoring convenient and safe access to the rear luggage compartment.

This part replaces the earlier Porsche part numbers 98151255103 and 98151255105.

What Does This Part Do? – Functions
  • Lid Support: Holds the rear lid securely in the open position.
  • Lifting Assistance: Reduces the effort required to open the rear hatch.
  • Controlled Movement: Provides smooth and stable lid operation.
  • Safety: Helps prevent the rear lid from closing unexpectedly.
  • Original Fitment: Maintains factory-correct operation and installation.

Why Replace This Part?
Over time, rear lid gas dampers can lose pressure due to ageing, frequent operation and temperature changes. A weakened damper may struggle to support the rear hatch, causing it to close unexpectedly or become difficult to lift.

Replacing a worn damper with a genuine Porsche component restores proper lifting assistance, secure lid support and smooth operation, helping maintain safety and everyday convenience.

When to Replace This Part?
  • Weak Support: Rear lid struggles to remain open.
  • Unexpected Closing: Hatch slowly lowers or drops without warning.
  • Difficult Opening: Increased effort required to lift the lid.
  • Visible Damage: Bent, corroded or leaking gas strut.
  • Worn Performance: Reduced lifting assistance or inconsistent operation.

Where Does It Fit on the Car?
Location: Rear body – rear hatch / tailgate assembly.

The gas-filled damper is fitted between the rear hatch and the vehicle body, supporting the lid during opening and closing.

It is suitable for installation on either the left-hand or right-hand side of the vehicle.

The rear tailgate damper is a gas-assisted support strut fitted between the vehicle body and rear tailgate. It provides controlled assistance when opening the tailgate and helps support its weight once fully raised.

This version is specifically for vehicles equipped with the rear window wiper (option code 425).

What this part does
  • Supports the weight of the rear tailgate
  • Assists when opening the tailgate
  • Helps hold the tailgate securely in the raised position
  • Provides controlled tailgate movement
  • Replaces weak or worn original gas struts
  • Suitable for vehicles with rear window wiper
  • Supplied as an OE Match replacement part

Why Replace This Part? 
Tailgate gas struts gradually lose pressure and lifting force with age and repeated use. Weak dampers may no longer support the tailgate correctly, causing it to fall or requiring additional effort to open. Common signs of worn tailgate dampers include:
  • Tailgate will not stay fully open
  • Tailgate slowly drops when raised
  • Increased effort is required to open the tailgate
  • Tailgate feels unusually heavy
  • Gas strut shows signs of leakage or damage

Replacing worn dampers restores proper support and safer tailgate operation.

When to Replace This Part
  • Tailgate no longer remains open
  • Gas struts have lost lifting force
  • Tailgate drops unexpectedly
  • Damper is leaking or damaged
  • Rear hatch components are being refurbished
  • One or both original dampers have deteriorated

Where it fits on the car
Fits to the rear tailgate / hatch assembly.
