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.

Rear Shock Absorber Top Mount & Overhaul Kit.
Restore the top mount of your Porsche 981 Boxster Spyder's rear shock/strut assembly with this full overhaul kit. Designed to fully renew the upper mounting interface.

Fits:
  • Porsche Boxster 981 Spyder 3.8L 2016

Diagram Ref No 2, 3, 4, 5, 6, 7, 8, 9, 11

What This Product Does:

  • The top mount (upper mount) of the shock/strut assembly is critical: it secures the top of the damper to the vehicle’s body/strut tower, supports the spring/damper load, and ensures correct alignment and isolation of vibration or noise.
  • Over time, mounts/washers/nuts can corrode, loosen, rubber can deteriorate (if included), or tolerances may degrade, leading to movement, noise, vibration or alignment issues. Replacing the full kit restores the interface — ensuring the shock absorber is properly anchored, loads are contained, and suspension geometry/behaviour maintained.

When You Should Consider Replacement:
  • Clunking, knocking or popping noises from the rear strut top area when driving over bumps, or when the suspension unloads/loads.
  • Excessive vibration or “thunk” from the rear when cornering or braking — indicating the top mount might be giving way.
  • Poor rear suspension feel / looseness in the rear – drifting feel, less precise handling than before.
  • Visual signs of wear – if you inspect the top mount area and find nut is loose, washers/show signs of corrosion, the cap or mount plate is damaged, or the mount has had previous repair.
  • During a shock absorber/strut replacement or rear suspension refresh – if you have the unit removed, it is highly efficient to replace the top mount kit at the same time, rather than later.

Why Replacement Matters:
  • Preserves handling & ride quality: A solid top mount ensures the damper is correctly loaded and held; any looseness or deterioration will degrade ride feel, stability, tyre contact patch and overall rear suspension behaviour.
  • Reduces noise, vibration & harshness (NVH): A failing top mount often transmits odd noises into the cabin — in a performance car like a Porsche, that detracts significantly.
  • Prevents further damage: If the mount fails, loads may transfer into the shock, spring seat or body structure incorrectly, leading to bigger and more expensive repairs.
  • Cost-effective proactive maintenance: When the top mount hardware is accessible (e.g. during shock replacement), replacing the full kit now avoids needing to disassemble again later for mount failure.
