Parts for your 2012 Mitsubishi Lancer-Coil springs

2012 Mitsubishi Lancer Coil Springs

Coil springs are indeed used on the 2012 Mitsubishi Lancer. Technical references including the Mitsubishi CJ Lancer Service Manual (Group 33 – Suspension) describe a MacPherson strut with a coil spring at the front and a multi‑link rear that uses separate coil springs. Major AU/NZ fitment catalogues (KYB, Monroe) and the Mitsubishi ASA parts catalogue list front and rear coil spring part numbers for 2012 ES, VR, Activ and GSR models, with performance‑rate coils specified for Ralliart and Evolution variants.

On this Lancer, the coil springs carry vehicle weight, set ride height and help soak up the rough stuff before it reaches the cabin. Working in tandem with the struts/shock absorbers, they keep the tyres planted for braking and cornering stability, and they preserve alignment angles that protect against uneven tyre wear. Correct spring rate is matched to engine, trim and equipment, so the car sits level and behaves predictably over Aussie and Kiwi backroads and motorways alike.

Coil springs don’t have a fixed service interval, but they do fatigue over time. Regular inspection during scheduled servicing is smart practice. Technicians look for cracked coating and rust, broken pigtail ends, coils that are touching, or a ride height that’s down on one corner. Any failure here affects braking, steering feel and tyre life. Common red flags include:

• Noticeable sag on one side or a “nose‑down” stance
• Clunks over bumps or a harsher, pogo‑stick ride
• Uneven or accelerated tyre wear despite correct pressures

When replacement is needed, best practice is to fit springs in axle pairs to keep rates balanced. Correct part selection by VIN/trim code matters—Ralliart/Evo springs are not interchangeable with base models. A proper spring compressor must be used, heating or clamping springs is unsafe and illegal. It’s also wise to renew upper mounts, isolators and dust boots while the struts are out, then torque all hardware at normal ride height. A four‑wheel alignment should follow any spring or strut change.

Coastal conditions in AU/NZ can accelerate corrosion, so underbody rinsing after beach trips helps longevity. Owners adding towing duties or frequent loads may opt for heavy‑duty coils, but any ride‑height change must meet local compliance and WOF/RWC rules. Get the right rate, keep the geometry true, and the Lancer will steer cleanly and ride comfortably for many kilometres.

• Are there common signs the 2012 Lancer’s coil springs are failing?
  Yes. A drooping corner, clunks over speed humps, or uneven tyre wear suggest a sagging or broken coil. Visual checks often show chipped paint, rust or a snapped end coil.
• Should coil springs be replaced with struts/shocks at the same time?
  Often recommended. Tired dampers can shorten new spring life and vice versa. Replacing them together restores ride height and control, and usually saves labour and a second alignment.
• Do sedan and Sportback Lancers use the same coil springs?
  Not always. Rates and free lengths vary by body style, engine, transmission and trim. Selection by VIN or spring code ensures the correct ride height and handling balance.
