Front Shock Absorber Top Mount & Overhaul Kit.
Restore the critical upper mounting point of your front suspension with this comprehensive overhaul kit. Designed for the front strut tower on Porsche 981 Boxster, this kit includes the top mount, bearing and all required hardware such as nuts, washers, bump stop/dust cover components.
Fits:

• Porsche Boxster 981 2.7L 2012-16 (For Cars Without PASM)
• Porsche Boxster 981 S / GTS 3.4L 2012-16 (For Cars Without PASM)

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.
  

Why Replacement Matters:

• 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.

Designed for compatible Porsche applications equipped with the specified M030 / M031 Sport Suspension, this kit provides replacement components for the front spring and suspension assembly. It is ideal for repairing a worn or damaged front suspension or carrying out a more comprehensive chassis refurbishment.

The front coil springs support the weight of the vehicle while allowing the wheels to move vertically over bumps and changing road surfaces. Working together with the shock absorbers and associated mounting components, the springs help determine ride height, suspension travel and the way the chassis responds during braking, cornering and acceleration.

Sport suspension systems depend on the correct spring specification to maintain their intended balance. A sagging, fractured or incorrect spring can change ride height and suspension geometry, potentially affecting steering response, handling, tyre wear and stability.

Replacing deteriorated components with this OE Match Front Coil Spring Kit helps restore the suspension closer to its intended operating condition.
What This Product Does:

• Support the weight of the front of the vehicle.
• Maintain the specified front ride height.
• Provide controlled suspension movement over uneven roads.
• Work together with the front shock absorbers.
• Maintain the intended M030 / M031 Sport Suspension characteristics.
• Support precise steering response.
• Maintain front-end stability.
• Help control body movement during cornering.
• Support stable behaviour under braking.
• Maintain appropriate suspension geometry.
• Keep the tyres in consistent contact with the road.
• Restore suspension performance where original components have deteriorated.
• Provide an OE Match replacement solution for compatible Porsche applications.  

Symptoms Of Wear Or Failure:

• Broken or fractured spring coils.
• Front of the vehicle sitting lower than normal.
• One front corner sitting lower than the other.
• Uneven ride height.
• Excessive suspension sag.
• Reduced ground clearance.
• Knocking or clunking from the front suspension.
• Metallic noises over bumps.
• Noise when steering.
• Spring incorrectly positioned within its seat.
• Increased body movement.
• Reduced steering precision.
• Unsettled handling.
• Suspension bottoming out.
• Vehicle pulling or behaving unpredictably.
• Uneven or accelerated tyre wear.
• Visible spring corrosion.
• Damaged spring coating.
• Cracks or significant deterioration around associated mounting components.  

Why Replacement Matters:

• Coil springs are fundamental load-bearing suspension components.
• They help maintain the designed relationship between the wheels, suspension and vehicle body. A damaged or weakened spring can alter this relationship and affect the way the chassis behaves.
• A completely fractured spring can also move from its intended seating position and potentially interfere with surrounding components.
• Replacing damaged or significantly deteriorated springs helps restore safe and predictable suspension operation.

Designed for compatible Porsche applications equipped with the specified M029 Standard Suspension, this kit provides replacement components for the front spring assembly and is ideal for repairing worn, damaged or ageing suspension components.

The front coil springs support the weight of the vehicle and allow the suspension to absorb bumps and changes in the road surface. Working together with the shock absorbers and associated mounting components, they help establish the correct ride height while maintaining controlled wheel movement, steering stability and predictable chassis behaviour.

Over time, coil springs can weaken, corrode, sag or fracture. Associated mounting components can also deteriorate through age, mileage and repeated suspension movement. These problems can result in uneven ride height, suspension noise, reduced handling precision and abnormal tyre wear.

Replacing deteriorated components with this OE Match M029 Front Coil Spring Kit helps return the front suspension to its intended operating condition.
What This Product Does:

• Support the weight of the front of the vehicle.
• Maintain the specified front ride height.
• Provide controlled suspension travel.
• Absorb changes in the road surface.
• Work together with the front shock absorbers.
• Maintain the intended M029 Standard Suspension characteristics.
• Support predictable steering response.
• Help maintain front-end stability.
• Control body movement in conjunction with the dampers.
• Support stable braking and cornering behaviour.
• Maintain appropriate suspension geometry.
• Keep the tyres in consistent contact with the road.
• Restore worn or damaged front suspension components.
• Provide an OE Match replacement solution for compatible Porsche applications.  

Symptoms Of Wear Or Failure:

• Broken or fractured spring coils.
• Front of the vehicle sitting lower than normal.
• One front corner sitting lower than the other.
• Uneven ride height.
• Excessive suspension sag.
• Reduced ground clearance.
• Knocking or clunking from the front suspension.
• Metallic noises when travelling over bumps.
• Noise during steering.
• Suspension bottoming out.
• Increased body movement.
• Reduced steering precision.
• Unsettled or inconsistent handling.
• Vehicle pulling to one side.
• Uneven or accelerated tyre wear.
• Visible corrosion on the springs.
• Damaged spring coating.
• Spring incorrectly seated.
• Cracked or deteriorated associated mounting components.  

Why Replacement Matters:

• Coil springs are load-bearing suspension components that play an important role in maintaining the vehicle's ride height and suspension geometry.
• A weakened, sagging or broken spring can alter the relationship between the wheel, suspension and vehicle body.
• A severely fractured spring can also move out of its intended seating position and potentially interfere with surrounding components.
• Replacing defective springs helps restore safe and predictable suspension behaviour.
