The Porsche Genuine OE Rear Engine Lid Damper (Part No. 99751255191) is an original factory gas-filled support strut / gas pressure damper designed for the rear engine lid assembly on high-performance Porsche 997 GT models.
1 required per vehicle
Fits:
Porsche 997.1 GT3 RS 2007 - 2013 (PR:004)
Porsche 997.2 GT2 2010 - 2013
Diagram ref no 4
The rear engine lid damper assists with lifting and supporting the engine cover while keeping it securely open during servicing or inspection.
The gas-filled design counterbalances the weight of the GT rear lid and spoiler assembly, ensuring controlled opening and preventing the lid from dropping unexpectedly. This is especially important on GT and RS models fitted with larger aerodynamic rear wings.
Functions & Technical Role
• Engine lid support: Assists lifting and holding the rear lid open
• Gas pressure operation: Provides smooth and controlled movement
• GT spoiler support: Designed for heavier GT and RS rear deck lids
• Service accessibility: Improves safe access to the engine compartment
• OEM precision: Manufactured to Porsche factory specifications for exact fitment and durability
Fitment / Position on Car
• Fitting position: Rear
• Location: Rear engine lid / rear deck lid assembly
• System: Rear lid lifting and support mechanism
• Typically fitted: Between the chassis mounting point and engine lid hinge assembly
The rear engine lid damper supports the heavy GT rear spoiler assembly and prevents sudden closing of the engine lid. A weak or failed damper can make the lid difficult to open and unsafe to hold in position.
When to Replace:
• Rear lid no longer stays open
• Weak or uneven lifting force
• Oil leakage from the gas strut
• Difficulty opening the engine cover
• During rear lid or spoiler restoration work
