Parts for your 2020 Subaru Legacy-Coil springs

2020 Subaru Legacy coil springs

Coil springs are fitted to the 2020 Subaru Legacy. Technical sources confirm this: the Subaru 2020MY Legacy/Outback Factory Service Manual (Suspension section) specifies a front MacPherson strut with a coil spring and a rear double‑wishbone suspension using coil springs, Subaru’s 2020 Legacy press information describing the Subaru Global Platform lists MacPherson-type front and double‑wishbone rear setups, and major parts catalogues (e.g., KYB and Monroe) publish front and rear coil-spring applications for the 2020 Legacy.

The coil springs on a 2020 Subaru Legacy do the heavy lifting: they hold the car up at the right ride height, keep tyres pressed to the road, and work with the shocks/struts to smooth out bumps. They’re tuned so the Legacy stays comfy on corrugated backroads while still feeling planted in the wet. On the front, the coils sit over the struts, down the back, the springs pair with separate dampers on the double‑wishbone arms.

They’re not a routine replacement item, but they do wear, especially with high kilometres, coastal corrosion, or if the car regularly tows or carries a full boot. It’s worth a check any time new shocks/struts go in, or if the ride height looks a bit wonky.

• Watch for a sagging corner, uneven tyre wear, or a nose‑up/boot‑down stance.
• Listen for clunks over speed humps or a twang on full lock.
• Look for chipped paint, rust, or a cracked/broken spring tail.
• Measure trim height side‑to‑side if the car feels floaty or vague.

When replacement’s due, do both springs on the same axle to keep handling balanced. Freshen the related bits while you’re there: front top mounts/bearings, insulators, spring seats and bump stops. Ask the workshop to torque the control arm bushes at normal ride height so nothing binds, and get a wheel alignment afterwards. Using the correct rate/length is key—staying with genuine spec or a reputable equivalent helps preserve the Legacy’s ride and the behaviour of its stability and driver‑assist systems. Spring compressors can bite, this is one job best left to a pro unless the proper gear and know‑how are on hand.

There’s no strict interval, but a yearly inspection works well in Aussie and Kiwi conditions. If the Legacy sees a lot of gravel, salt air or towing, shorten that to every 10,000–20,000 km alongside regular servicing.

Do the 2020 Legacy’s coil springs need replacing with the shocks/struts?
Not always, but it’s smart to assess them together. If the struts are tired and the car has high kilometres, pairing new dampers with fresh springs restores ride height and feel. If springs show no sag, cracks or corrosion, they can sometimes stay.

How long do factory coil springs typically last on a 2020 Legacy?
Often well past 150,000 km, but coastal corrosion, heavy loads and rough roads can shorten that. Regular inspections and cleaning off road grime and salt help extend life.

Can the 2020 Legacy run heavy‑duty or raised springs?
It can, but stick close to proven, road‑legal options. Changing rate or height affects alignment, headlight aim and handling. If towing or carrying loads, consider springs that match the intended use and get an alignment after fitting.
