A genuine Porsche coil spring pair, manufactured to exact OEM specifications for material quality, dimensional accuracy, and performance consistency. This set includes two springs, designed to be installed together to maintain correct suspension balance.

These springs support the vehicle’s axle load and control suspension movement during braking, acceleration, and cornering. Replacing both springs as a matched pair ensures even ride height, correct weight distribution, and predictable handling response.

Installed within the suspension assembly, the coil springs compress and rebound with suspension travel to absorb road impacts and stabilise the vehicle body. Their precisely calibrated spring rates work in harmony with Porsche dampers to maintain tyre contact, steering precision, and ride comfort.

When to replace:
• Ride height has sagged or become uneven
• Springs show signs of fatigue, corrosion, or damage
• During shock or strut replacement
• Suspension refurbishment or alignment correction
• Reduced handling precision or ride comfort
