Rear monoball shock mount - Set of 2


Fits:
Porsche 986 Boxster
Porsche 987.1 Boxster
Porsche 987.2 Boxster

Porsche 987C.1 Cayman
Porsche 987C.2 Cayman

Ultimate replacement for factory rubber bush mount. Compatible with OE and aftermarket struts.

CNC machined 6061 anodized aluminum construction with stainless steel hardware.

Reduces rear wheel camber changes during hard cornering to maintain optimum tire contact for improved traction.
Increased monoball life due to spring load being distributed over the domed housing.

*Note: Not compatible with Ohlins or similar Coilover suspension.

Upgrade your vehicle's suspension with this high-performance monoball top mount, designed as a direct replacement for the original OE top mount. By replacing the compliant rubber bushing with a precision spherical bearing (monoball), unwanted suspension deflection is significantly reduced, providing a more direct connection between the suspension and chassis.

The result is improved suspension rigidity, sharper steering response, and more precise handling, allowing the suspension geometry to remain more consistent under high cornering and braking loads. This makes monoball top mounts an ideal upgrade for performance driving and motorsport applications where maximum steering precision and chassis feedback are desired.

Please note that, due to the elimination of the original rubber isolation, increased road noise, vibration, and harshness (NVH) will be transmitted into the cabin. Ride comfort will be reduced, and suspension noise may become more noticeable during normal road use.

Key Features:

• Direct replacement for the original OE top mount.
• Precision monoball (spherical bearing) design.
• Increased suspension rigidity.
• Quicker, more responsive steering.
• Improved handling and suspension geometry control.
• Ideal for performance and motorsport applications.

Important Information:
This product is recommended for track use only. The increased noise, vibration, and reduced ride comfort make it unsuitable for drivers seeking OE levels of refinement for everyday road use.

What This Product Does

This supporting mount forms part of the rear shock absorber and coil-spring assembly. It provides the upper mounting interface for the damper, helping to locate the assembly correctly and isolate unwanted movement at the mounting point.

Functions

• Supports the rear shock absorber at its upper mounting point
• Helps maintain correct location of the damper assembly
• Connects the rear damper assembly to the vehicle body
• Helps limit movement and noise from a worn mounting point

Technical Details

• Brand: OE Match
• Installation position: Rear
• Quantity required: 2 per car
• Suitable for left- or right-hand rear installation
• Diagram ref no 2

Symptoms of Fault

• Knocking or rattling from the rear suspension over uneven surfaces
• Harsh impacts or increased vibration entering the body
• Loose movement around the upper shock absorber mounting point
• Vague or unsettled rear suspension behaviour
• Premature wear affecting the damper or associated mounting hardware

Why Replacement Matters

A worn supporting mount can allow unwanted movement within the rear damper assembly, resulting in noise and reduced suspension control. Inspection is advisable when replacing rear shock absorbers, particularly if the existing mounts are aged, perished or loose. Related bump stops, dust covers, spring supports and mounting hardware should also be checked while the assembly is removed.

FAQs

• How many mounts are required? 2 Per car. Price is each.
• Should both rear mounts be inspected together? Yes. Checking both sides helps identify uneven wear and supports balanced rear suspension operation.
• Should other components be checked during installation? Inspect the rear dampers, bump stops, dust covers, spring supports and mounting hardware while access is available.
• Is suspension alignment recommended afterwards? An alignment check is advisable following significant suspension work or where uneven tyre wear is present.

Diagram Ref No 9

What This Product Does:

• The suspension nut secures the strut mount at the top of the shock absorber/strut assembly (commonly where the strut rod passes through the strut mount at the top of the strut-tower).
• It ensures that the strut (and thus the spring/damper) remains firmly attached at the top mount location, holding the relative positioning of the strut to the chassis/strut tower.
• Being a correct OEM nut means correct thread, correct material/hardeness, correct torque specification and compatibility with the mount parts, lock washers or locking features.

Why Replacement Matters:

• Safety & structural integrity: A loose or improperly torqued strut top nut can allow the strut mount to move or shift, which compromises the suspension’s secure attachment to the chassis. This can lead to unwanted movement, misalignment or even failure under load.
• Ride quality & handling: The top mount of the strut affects how the suspension behaves under load. If the nut is loose or the mount isn’t held securely, you may get clunks, creaks, top plate movement, steering imprecision or increased noise. Replacing or confirming this nut ensures the mount is properly clamped.
• Part of correct service: When servicing or replacing struts, mounts, bearings or top mount assemblies, replacing the nut (often a single-use or recommended torqued fastener) is good practice. Failing to replace can leave a weak link in the suspension.
