Diagram ref no 10
This coil spring supports one front corner of the vehicle, managing suspension compression and rebound during braking, acceleration, and cornering. It contributes to stable ride height, predictable handling, and balanced suspension response.
Installed between the lower control arm and the front strut assembly, the spring compresses and expands with suspension travel. It absorbs road impacts, controls body movement, and helps maintain proper tyre contact, steering accuracy, and 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, tyre wear, and comfort. Replacing tired springs with new components restores factory-style suspension balance and driving confidence.
Replace this part if you experience any of the following:
• Uneven or sagging front ride height
• Excessive body roll or unstable handling
• Cracks, corrosion, or visible spring fatigue
• Suspension overhaul, shock absorber replacement, or alignment work
• After significant mileage or heavy track/road use
