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.
