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.

Why Replacement Matters
A deteriorated damper can affect rear hatch support and movement. Replacement addresses a confirmed component fault, while checking the associated mounting points and electrical connections helps avoid overlooking another cause. Match the original reference and chassis details before fitting.
