This spring set supports the axle load and manages suspension movement during braking, acceleration, and cornering. Replacing both springs together ensures even load distribution, symmetrical ride height, and predictable handling characteristics.
Installed within the suspension assembly, the coil springs compress and rebound with suspension travel to absorb road impacts and stabilise the vehicle body. Working together as a matched pair, they help maintain consistent tyre contact, steering precision, and ride comfort.
Coil springs weaken and sag over time due to constant load, mileage, and road conditions. Replacing only one spring can result in uneven ride height and compromised handling. Installing a pair restores correct suspension geometry, factory stance, and predictable driving dynamics.
When to replace:
• Ride height has sagged or become uneven
• Springs show fatigue, corrosion, or damage
• During shock or strut replacement
• Suspension refurbishment or alignment correction
• Reduced handling precision or ride comfort
