Diagram ref no 7

This coil spring supports one front corner of the vehicle, managing suspension compression and rebound during braking, acceleration, and cornering. It helps maintain proper ride height and contributes to stable, predictable handling.

Installed between the lower control arm and the front strut assembly, the spring compresses and expands with suspension travel, absorbing road impacts and controlling body movement. Correct spring performance is essential for maintaining tyre contact, steering accuracy, and overall ride comfort.

Over time, coil springs can weaken or sag due to constant load, mileage, and road conditions. A worn spring can alter ride height and suspension geometry, affecting handling and tyre wear. Replacing tired springs restores factory-style suspension balance and driving confidence.

When to replace:
• Front ride height appears uneven or sagging
• Increased body roll or reduced handling precision
• Visible corrosion, cracks, or spring fatigue
• During front shock or strut replacement
• As part of a front suspension refresh
