Parts for your 2018 Mitsubishi Asx-Coil springs

2018 Mitsubishi ASX Coil Springs

Coil springs are absolutely fitted to the 2018 Mitsubishi ASX. This is confirmed by Mitsubishi’s factory service manual for the GA-series ASX/RVR/Outlander Sport (front MacPherson strut with coil spring, rear multi-link with coil springs), the 2018 ASX owner’s manual specifications, and OEM parts catalogues that list front and rear coil spring components for this model.

On the 2018 ASX, the coil springs carry the vehicle’s weight, set ride height, and keep the tyres planted over bumps. Up front they wrap around the MacPherson struts, and down the back they work with the multi‑link setup to balance comfort and control. That combination is why the ASX feels settled on choppy suburban roads and steady on highway sweepers.

While coil springs don’t have a fixed replacement interval, they do fatigue over big kilometres, rough corrugations, heavy loads, or salt exposure near beaches. As part of regular servicing (around every 15,000 km or annually), a technician should check for sagging, cracked paint, heavy rust pitting, broken coils, and collapsed or perished rubber seats/isolators. A quick look at ride height side‑to‑side and a road test for clunks or creaks over speed bumps also tell a story.

• Replace springs in axle pairs to keep handling and ride height even.
• Use a proper spring compressor—coil springs store serious energy, DIY without the right gear is risky.
• Fit quality components matched to ASX specs to maintain comfort and stability control calibration.
• Book a wheel alignment after spring work—ride height changes can nudge camber and toe.

For ASX owners who tow or load up for holidays, keep an eye on rear ride height and tyre wear patterns. If the car sits low in the tail or bottoms out over driveway entries, the rear coils may be tired. In coastal Aussie and Kiwi conditions, rinse the underbody after beach trips, surface rust on the coils is common, but deep pitting near the ends can lead to a snapped coil.

Thinking of lift or lowering springs? It’s doable, but staying close to OEM rates keeps the ASX’s all‑round balance. In NZ, check if modifications need certification, in both countries, ensure WOF/safety inspections are happy with any changes.

Popular questions

How long do coil springs last on a 2018 ASX?
Many sets go well past 150,000 km, but lifespan depends on loads, roads, and corrosion. If you notice a lean to one side, clunks, or reduced ride height, get them inspected sooner rather than later.

Should coil springs be replaced in pairs?
Yes—replace both fronts or both rears together. That keeps ride height even and handling consistent, and helps avoid uneven tyre wear.

Do new springs require a wheel alignment?
It’s strongly recommended. Changing springs alters ride height, which can shift alignment angles. An alignment helps protect tyres and keeps steering feel on point.
