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.

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.
