Diagram ref no 6
This component is essential for maintaining ride quality, suspension stability, and correct shock absorber operation. Over time, bump stops can deteriorate due to heat cycles, age, moisture, and repeated suspension compression, leading to cracking, collapse, or reduced cushioning performance. Replacing worn bump stops helps restore proper suspension protection and ensures the shock absorber can operate correctly throughout its full range of movement.
Functions & Technical Role
• Protects the front shock absorber during full suspension compression
• Prevents harsh bottoming-out impacts
• Helps maintain correct suspension geometry under load
• Reduces shock absorber and strut damage caused by excessive travel
• Assists with vibration damping and ride refinement
• Supports optimal PASM suspension performance
• OE-quality material construction for long-term durability
Fitment / Position on car
• Front suspension
• Fits left or right side
• Mounted on the front shock absorber/strut assembly
The front bump stop is a critical protective component within the Porsche suspension system. During heavy cornering, sudden impacts, aggressive driving, or rough road conditions, the suspension can compress rapidly. Without a properly functioning bump stop, excessive suspension travel can damage the shock absorber, strut mount, spring assembly, and other suspension components.
A deteriorated or collapsed bump stop may also lead to harsh suspension noises, reduced ride comfort, poor damping control, and premature shock absorber wear. Replacing worn bump stops with Genuine Porsche components helps maintain factory suspension performance, protects expensive suspension hardware, and preserves the precise handling characteristics Porsche vehicles are known for.
When to replace. Replace the front shock absorber bump stop if you notice:
• Cracked, split, or crumbling rubber material
• Suspension knocking or bottoming-out noises
• Excessive harshness over bumps
• Oil leaks or damage around the shock absorber
• Suspension overhaul or shock absorber replacement
• Visible compression damage or deterioration
• Reduced suspension damping performance
• High mileage or ageing suspension components

The bump stop compresses when the suspension approaches full travel, preventing harsh metal-to-metal contact within the shock absorber assembly.
It absorbs impact forces generated during:
• Heavy braking
• Road impacts and potholes
• Aggressive cornering
• High-load suspension compression
This helps protect the shock absorber, top mount, spring seat, and chassis from excessive stress while maintaining vehicle stability and ride quality.
Functions & Technical Role
• Suspension protection: Prevents shock absorber bottoming-out
• Impact absorption: Cushions heavy suspension compression
• Ride quality support: Reduces harsh impacts and vibration transfer
• Component longevity: Protects dampers, mounts, and springs from damage
• OEM precision: Engineered to Porsche suspension specifications for correct compression characteristics
The bump stop also works as a secondary progressive spring during extreme suspension movement, helping maintain chassis composure and handling balance.
The bump stop protects the suspension system from harsh bottoming-out during heavy compression. It helps preserve ride quality, reduces stress on the shock absorber assembly, and maintains proper handling characteristics.
When to replace
• Suspension bottoming-out or harsh impacts
• Cracked, split, or deteriorated foam/rubber
• Knocking noises from the suspension
• During shock absorber or suspension overhaul
• Reduced ride comfort or suspension control

Diagram Ref No 2, 3, 4, 5, 6, 7, 8, 9, 13
What This Product Does:
- The shock absorber top mount (sometimes called “strut mount” or “upper mount”) attaches the top of the front damper/strut assembly to the vehicle’s body/strut tower. It supports the spring/damper load, allows steering movement (via the bearing), and isolates noise/vibration.
- Over time, the rubber mount may degrade, the bearing can bind or wear, hardware may corrode — leading to poor ride, noise, loss of precision.
- The overhaul kit replaces the mount, bearing and all relevant hardware so the top of your front suspension is restored to correct specification — improving longevity, ride quality, handling, and eliminating common wear symptoms.
When You Should Consider Replacement:
- Knocking, creaking or clunking from the top of the strut tower when driving over bumps or turning the steering wheel.
- Steering or handling feel degraded: less precision, vague feedback, increased body roll, front-end wander.
- Suspension ride quality worsened, front-end noise or vibration transmitted into the cabin.
- You are replacing front shocks/struts: since the top mount must be removed for that job, it’s efficient to replace the mount/bearing/hardware at the same time.
- Mount or bearing visibly worn: If inspection shows the mount rubber cracked, bearing flattened or play exists, the overhaul kit is justified.
- Preserves ride & handling performance: The front suspension’s mount integrity influences tyre contact patch, cornering stability, and steering precision. A worn mount can compromise all of these.
- Eliminates noise & improves NVH: Worn mounts or bearings contribute to noise, creaks, clunks and general poor ride comfort. Replacing them improves refinement and comfort.
- Prevents further damage: If the top mount fails or deforms, the strut, spring seat, bearing or body mounting may suffer damage. A fresh kit protects the rest of the suspension.
- More cost-effective in service: Since the strut top mount is accessed when the strut is removed, it’s efficient to replace the mount kit at the same time rather than later.

Restore the critical upper mounting point of your front suspension with this comprehensive overhaul kit, designed for Porsche 981 Boxster Spyder front strut-tower applications.
Fits:
- Porsche Boxster 981 Spyder 3.8L 2016
Diagram Ref No 2, 3, 4, 5, 6, 7, 8, 9, 13
What This Product Does:
- The front shock absorber (strut) top mount (sometimes called “strut mount,” “upper mount,” or “mount cap & bearing”) is the part that mounts the top of the front damper/strut to the vehicle’s body (strut tower). It carries spring and damper load, provides a secure connection to the chassis, and often includes a bearing to allow the strut to rotate with steering movement.
- Over time, the top mount’s rubber or elastomer may degrade, the bearing may develop play or noise, the mount plate may shift, washers/nuts may loosen, dust covers may deteriorate. This results in increased noise, worse ride/handling, and possible mis-alignment of the strut.
- This overhaul kit replaces the mount, bearing and all relevant hardware so you restore that top mount area to like new, ensuring proper load path, better durability, reduced noise and proper steering/handling characteristics.
- Clunking, knocking or creaking noises from the front strut-tower area when going over bumps or during steering input — a typical symptom of a worn mount or bearing.
- Steering feel or front suspension feel has degraded — loose, vague feel, or mis-alignment under load (cornering) can be caused by mount movement or bearing play.
- Ride comfort has worsened — a degraded mount transmits more road vibration or noise into the cabin.
- You are replacing the front shocks/struts or doing front suspension work — since the top mount is removed/loosened for such work, renewing the mount and hardware at the same time is highly recommended.
- Visual inspection may show a cracked or separated mount rubber, bearing play, rusted or worn nuts/bolts, or installer notes of mount movement when the top is pushed.
- Restores front suspension performance & precision: The top mount is key to how the front suspension loads up and behaves. A degraded mount allows unwanted movement under load, which reduces tyre contact patch consistency, reduces handling precision, and can upset steering feel.
- Eliminates noise & improves ride comfort: Many mount failures manifest as clunks, squeaks, or increased vibration. The full kit replacement addresses the entire assembly, not just one failing piece.
- Prevents more serious damage: If the mount is loose or the bearing is worn, the load path through the strut stack may shift, leading to premature damper shaft wear or strut tower load concentrations.
- Cost-effective timing: Since the top mount requires strut removal or top tower access, doing the full kit while you have that access is efficient and avoids re-doing labour.

This OE match front shock absorber bump stop is a direct replacement for the original Porsche suspension component fitted to selected Porsche 981 Boxster/Cayman, 991 Carrera/Turbo, and 982 (718) models. Manufactured to OE specifications, it is engineered to provide progressive cushioning during extreme suspension compression while maintaining factory ride and handling characteristics.
Installed on the front shock absorber shaft beneath the protective dust boot, the bump stop acts as a secondary suspension cushion. During heavy suspension compression caused by cornering, braking, potholes, or uneven road surfaces, the bump stop absorbs impact energy before the suspension reaches its mechanical limit. This helps prevent metal-to-metal contact and reduces stress on the damper, suspension mounts, and chassis.
The bump stop cushions the suspension when the shock absorber reaches near full compression. It helps absorb impact forces, protects suspension components from damage, and maintains stable suspension operation under demanding driving conditions.
Function
• Cushions suspension at full compression
• Protects shock absorber from excessive impact loads
• Prevents metal-to-metal suspension contact
• Helps maintain stable ride and handling characteristics
• Reduces stress on suspension mounts and chassis
Over time, suspension bump stops can deteriorate due to repeated compression, heat, moisture, and age. A damaged or collapsed bump stop may reduce suspension protection, increase harsh impacts, and accelerate wear on shock absorbers and mounting components. Replacing worn bump stops restores proper suspension cushioning and helps maintain ride comfort and handling precision.
When to replace
• Cracked, crumbling, or compressed bump stop material
• Harsh suspension impacts over bumps
• During shock absorber replacement or suspension servicing
• Increased suspension noise or bottoming-out sensation
• Preventative maintenance on high-mileage vehicles

This OE match front shock absorber bump stop is a direct replacement for the original Porsche suspension component fitted to selected Porsche 981 Boxster/Cayman, 991 Carrera/Turbo, and 982 Boxster/Cayman models. Manufactured to OE specifications, it is engineered to provide progressive cushioning during heavy suspension compression while preserving factory ride quality and handling precision.
Installed on the front shock absorber shaft beneath the protective dust boot, the bump stop acts as a secondary suspension damper. During aggressive cornering, braking, uneven road conditions, or pothole impacts, the bump stop absorbs excess compression energy before the suspension reaches its mechanical limit. This helps prevent metal-to-metal contact and reduces stress on the shock absorber, suspension mounts, and chassis components.
This component is commonly replaced during shock absorber servicing, suspension refurbishment, or preventative maintenance to restore proper suspension protection and ride refinement.
Function
• Cushions front suspension at full compression
• Protects shock absorbers from excessive impact loads
• Prevents metal-to-metal suspension contact
• Helps maintain stable ride quality and handling
• Reduces stress on suspension mounts and chassis components
Over time, bump stops can deteriorate due to repeated compression, age, heat exposure, and road contamination. A damaged or collapsed bump stop may allow harsh suspension impacts, increased vibration, and premature wear of the shock absorber and mounting components. Replacing worn bump stops restores suspension protection, ride comfort, and correct damper operation.
When to replace
• Cracked, crumbling, or compressed bump stop material
• Harsh impacts or bottoming-out sensation
• Increased suspension noise or vibration
• During shock absorber replacement or suspension servicing
• Preventative maintenance on higher-mileage vehicles
