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.

Suspension Strut Mount Cap.

Restore the finish and protection of your Porsche’s front strut mount area with this genuine OEM cap. Designed for front strut towers, this cap conceals and protects the top mount hardware while ensuring the correct, factory-look finish.
Sold Each.
x2 Required Per Car.

Fits:

• Porsche Boxster 981 Spyder 3.8L 2016

Diagram Ref No 5

What This Product Does:
As a mount cap/cover, the part’s function is protective and cosmetic:

• It covers the strut top mount area (or mount stud head) to prevent debris ingress, protect the mount from contamination (dirt, moisture) and give a finished appearance.
• Helps maintain aesthetics — ensuring exposed mount nuts/studs are covered with a clean, OEM-looking cap.
• May provide minor protective sealing from water/dust ingress at the top mount.
• Although it doesn’t carry suspension load (the structural mount does), it contributes to the overall integrity of the mount area by protecting the components underneath.

When You Might Replace It:

• The current cap is missing, cracked, faded or damaged — for example after a strut replacement, mount servicing, or accident repair.
  
• Age and weathering: UV exposure, road salt, mechanical abrasion can degrade plastic or composite cap surfaces, so replacing restores clean finish.

Why Replacement Matters:

• Completeness & aesthetic integrity: For premium vehicles like Porsche, even small parts contribute to the overall finish and perceived value. A missing or damaged cap looks like unfinished repair or poor maintenance.
  
• Protection of the mount internals: While small, the cap helps shield the top mount/stud from debris or moisture — over time this can reduce corrosion or wear on the underlying mount hardware.
  
• Cost-effective preventive maintenance: While inexpensive, replacing a worn cap when you already have access (e.g., strut mount service) is easy and avoids future minor annoyance or mis-match.
