Ensure the rear of your Porsche remains dialled in with this full top-mount overhaul kit for the rear shock/strut assembly. This comprehensive kit includes the upper mount, bearing/bushing, washers and hardware and is designed for direct replacement of worn or fatigued rear mount assemblies.
Fits:
- Porsche Boxster 987 2.7L 2006 -08/08 Cars with PASM
- Porsche Boxster 987 S 3.2/3.4L 2006-08/08 Cars with PASM
Diagram Ref No 2, 3, 4, 5, 7, 8, 9
What This Product Does:
- The top mount supports the top of the shock/strut: it holds it firmly in place while carrying the loads from the damper, spring and suspension movement. It also helps isolate unwanted noise/vibration from the car body.
- Over time the rubber mount may compress, degrade or split; the bearing/bushings may have play; hardware may have fatigue or corrosion. This causes unwanted movement, noise, ride/handling degradation.
- This overhaul kit replaces the mount and all associated hardware so the top of the damper is restored to correct geometry, correct mount stiffness and correct isolation.
Key Symptoms & When You Should Replace:
- Knocking, clunking or popping noises from the rear suspension when going over bumps or during load changes.
- Rear ride quality has deteriorated: more harshness, more vibration, or the rear feels “loose” or vague under cornering.
- Rear tyre wear or handling feel issues which could be caused by mount movement.
- You are already replacing rear shocks/struts or doing significant rear suspension work — this is an ideal time to renew the top mounts as preventative maintenance.
- Mount hardware is visibly degraded, bushings worn, or mount top plate shows signs of fatigue or rust.
Why Replacement Matters:
- Restores rear suspension performance & precision: A worn top mount allows unintended movement under load, which reduces handling precision, tyre contact and can degrade stability — especially important in a performance-oriented car.
- Eliminates noise & vibration: A tired mount often produces noise: clunks, creaks or vibrations. A fresh mount kit restores quiet operation.
- Prevents further damage: If the mount fails, the extra movement can lead to wear of the damper shaft, spring seat, or even cause damage to the strut tower or body mounting point.
- Efficient maintenance: Since access to the top mount is easiest when the rear damper is out or suspension is disassembled, doing the full kit replacement while you’re doing other rear suspension work is cost-effective.

Information
Shock absorber additional spring.
The replacement helper spring / bump stop assembly for the rear shock absorber on Porsche 987 Boxster and Cayman vehicles. This bump stop is designed to sit atop or within the rear shock/strut assembly, supporting the suspension’s load under compression, preventing harsh bottoming, and helping maintain ride height and handling balance. Manufactured to match Porsche’s original specification in terms of dimensions and elasticity.

• Position on Vehicle: Rear suspension, installed within or adjacent to the shock absorber/strut assembly on the rear axle - acts as secondary support (helper spring) or as bump stop to cushion full compression of the suspension.
• Applications: Ideal when your rear suspension exhibits signs of bottoming, excessive squat under load, or the helper-spring/bump stop is missing, fatigued or deformed - improving ride quality, maintaining correct ride height, and preserving handling performance.
The helper spring / bump stop is a critical yet often overlooked component of the rear suspension system. It steps in under heavier loads, sharp compressions or lowered ride-height scenarios to prevent suspension harsh-bottoming, maintain ride height and preserve handling geometry. When the part is worn or missing, you may experience a harsh “clunk” on full compression, inconsistent ride height, rear suspension instability or accelerated wear of other suspension components. Replacing it restores correct support, prolongs suspension life and ensures your car handles the way it was engineered.
When and why to replace:
• Rear suspension bottoms out prematurely under moderate load or when cornering.
• Noticeable change in ride height, rear sagging or uneven posture under load.
• After replacement of rear shock absorbers or other suspension components where the helper spring/bump stop may have been removed or reused.
• High-mileage vehicle where the original component may have degraded or compressed with age.
• If you have lowered or modified your suspension and want to ensure secondary support matches the rest of the system.
