Rear coil springs are responsible for supporting the vehicle’s weight at the rear axle while absorbing road impacts and maintaining correct suspension geometry. Over time, springs can weaken, sag, or crack due to age, corrosion, or repeated stress, leading to uneven ride height, poor handling, suspension noise, and abnormal tyre wear.
Replacing worn rear springs helps return the vehicle to its intended factory stance and improves driving stability under acceleration, braking, and cornering. These springs are engineered to OEM specifications for correct fitment and spring rate, ensuring a safe, predictable ride when paired with matching shocks and suspension components.
Ideal for maintenance, suspension refresh projects, or ride-height correction, this rear spring pair provides reliable performance and long-term durability for a properly balanced suspension setup.
What This Product Does:
- Support the vehicle’s rear weight and chassis load
- Maintain proper ride height and suspension geometry
- Absorb bumps and road impacts for improved comfort
- Keep the car stable during cornering, braking, and acceleration
- Work together with shocks/struts to control suspension movement
Symptoms Of Worn Or Damaged Coil Spring:
- Rear of the car sitting low or uneven (sagging stance)
- Clunking or knocking noises over bumps
- Poor ride quality or “bouncy” handling
- Uneven tyre wear from altered alignment/geometry
- Visible cracks, corrosion, or broken spring coils
- Instability under braking or cornering
Why Replacement Matters:
- Restore correct ride height and suspension balance
- Improve stability, comfort, and predictable handling
- Prevent excessive strain on shocks/struts and suspension mounts
- Maintain correct wheel alignment and tyre wear
- Keep the vehicle safe and enjoyable to drive
