Rear lid dumper
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.
Sold individually. Two dampers are required per vehicle when replacing both left and right sides. Replacing both together is recommended when they have weakened with age.

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.

What This Product Does

The damper provides support for the rear engine cover during opening and while raised, allowing access to the engine compartment. OE Match develops replacement components around Porsche applications, using original references and vehicle specifications to assess suitability.

Functions

  • Assists engine-cover lifting.
  • Supports the raised rear lid.
  • Helps control lid movement.

Technical Details

  • Construction type: gas-filled strut.
  • Installation position: rear engine lid.
  • Supplied references: 99151255100, 99151255101 and 99151255102.
  • The 991.1 and Turbo diagrams specify two struts per vehicle under reference 99151255102.
  • The 2016 GT3 CUP diagram specifies two struts under reference 99151255100.

Symptoms of Fault

  • The raised cover no longer stays supported.
  • The lid sinks from a partially open position.
  • Fluid traces appear around the piston rod.
  • Operation produces creaks or knocks.

Why Replacement Matters

A weakened support can leave the cover difficult to raise or unable to remain open. Renewing a faulty damper addresses lost lid support; inspect the mounting points and any second strut when assessing the repair.

FAQs

Is this a pair?
No. Dampers are supplied individually; the listed road-car diagrams specify two per vehicle.

How should compatibility be checked?
Compare the original reference with the supplied numbers and confirm the exact model, production year and rear-cover specification, including any spoiler or wing equipment.
