Engine mounts play a critical role in stabilising the engine and drivetrain, helping maintain alignment under acceleration, cornering, and braking. Over time, original mounts can wear, harden, or crack, leading to excessive engine movement, increased vibration, abnormal noise, and, in some cases, drivetrain stress. Replacing worn mounts with a quality LEMFÖRDER unit restores proper support, reduces unwanted vibration, and helps maintain smooth driving characteristics.
Manufactured by LEMFÖRDER, a respected supplier of suspension and powertrain mounting systems, this engine mount is constructed with robust materials and precision engineering for durability and long service life. It’s a direct fit for affected 718 models, offering reliable performance and peace of mind for everyday driving or spirited use.

What This Product Does
The hydraulic mounts connect the gearbox assembly to the vehicle structure, supporting its position and damping vibration transferred through the drivetrain. Their controlled movement also helps maintain the intended alignment of the transmission, linkage and surrounding components during acceleration, braking and gear changes.
Functions
- Supports the gearbox in its installed position
- Damps vibration transmitted from the drivetrain
- Controls transmission movement under changing loads
- Helps maintain gearbox and linkage alignment
- Reduces stress caused by excessive drivetrain movement
Technical Details
- Part number: 98137504902
- Contents: two hydraulic gearbox mounts
- Mount type: non-dynamic hydraulic mounting
- Application code: PR:-140
- For vehicles without option code 140, Porsche Active Drivetrain Mounts (PADM)
- Diagram group: transmission suspension and threaded joint
Symptoms of Fault
- Increased vibration through the cabin at idle or low speed
- Thumps or clunks when engaging gear or changing throttle load
- Noticeable drivetrain movement or shunt
- Less precise or inconsistent gear-change feel
- Exhaust or nearby components knocking as the drivetrain moves
- Visible mount deterioration, collapse or hydraulic leakage
Why Replacement Matters
Age, heat cycling and repeated drivetrain loads can reduce a hydraulic mount's ability to control gearbox movement. Replacing worn mounts as a matching pair helps provide balanced support, restores the intended isolation between the transmission and body, and limits avoidable strain on the linkage, exhaust connections and related components. Other potential causes of vibration or poor shifting should be checked before replacement.
FAQs
- Are these mounts suitable for cars with PADM?
No. This set is specified for vehicles without Dynamic engine mounts (PADM), identified by application code PR:-140. - Does the set contain both required mounts?
Yes. The supplied diagram data specifies a vehicle quantity of two, and this package contains two mounts. - Will replacing the mounts repair gearbox crunching?
Not necessarily. Worn mounts can affect drivetrain movement and shift feel, but crunching may also indicate clutch, linkage or internal transmission wear. - Should related hardware be inspected?
Yes. Check the mounting consoles, sleeves, nuts and bolts during installation and renew any items that are damaged or specified as one-time-use.

Diagram: 306-000, item 7 (Boxster / Cayman); item 4 (Cayman GT4).
What This Product Does
The mount connects the gearbox to its supporting structure, holding the transmission in position while damping vibration and allowing controlled movement under load. It works with the other powertrain mounts to maintain drivetrain alignment.
Functions
- Supports the transmission at its mounting point.
- Limits unwanted gearbox movement during changes in load.
- Isolates drivetrain vibration from the vehicle structure.
- Helps maintain alignment of connected drivetrain components.
Technical Details
- Part number: 98137504902.
- Brand: OE Match.
- Hydraulic, non-dynamic gearbox mounting.
- Internal diagram application code: PR:-140.
- Diagram quantity: two mounts per vehicle; this identifies the assembly requirement, not a supplied pair.
- Diagram applications include 981 Boxster / Boxster S 2012–16, 981C Cayman / Cayman S 2014–16 and 981C Cayman GT4 2016.
Symptoms of Fault
- A knock or thud as drive is taken up or released.
- More vibration felt inside the cabin.
- Excessive powertrain movement or an unsettled gearshift feel.
- Visible cracking, sagging or collapse of the mount.
- Fluid seepage from a deteriorated hydraulic mounting.
Why Replacement Matters
A worn mounting may no longer support the gearbox or damp movement as intended. Renewing a confirmed faulty mount addresses that loss of support and helps limit movement that can load adjacent connections. Inspect the remaining mounts, brackets and fasteners during the repair, rather than assuming every vibration or shifting concern originates here. OE Match focuses on replacement components for Porsche applications, with specification and fitment assessment forming part of its development process.
FAQs
- Is this the dynamic PADM version?
No. The supplied application specifies vehicles without dynamic engine mounting. - Will replacement resolve grinding during shifts?
Not necessarily. Clutch, linkage or internal transmission wear can cause similar complaints and needs separate diagnosis. - Should both gearbox mounts be inspected?
Yes. The diagrams show two mounting positions, so assess both mounts and their supporting hardware when planning the repair.
