Parts for your 2012 Holden Commodore-Coil springs

2012 Holden Commodore coil springs — purpose, care and when to replace

Coil springs are absolutely fitted to the 2012 Holden Commodore. Holden service literature for the VE Series II and the GM Zeta platform specifications list coil springs at the front MacPherson struts and at the independent rear. Technical references such as workshop manuals and parts catalogues confirm there are no torsion bars, leaf springs or air springs in standard 2012 Commodore passenger models.

On a 2012 Commodore, the coil springs carry the vehicle’s weight, set ride height, and let the shocks do their job keeping the tyres planted. They balance comfort and control across Aussie and Kiwi roads, from motorway corrugations to tight back-country bends. Different trims (FE1/FE2/FE3) use varied spring rates to tune body control, braking stability and cornering feel.

Coil springs aren’t a consumable with a fixed interval, but they deserve regular checks. A quick look at each service helps catch issues before they snowball. Signs it’s time to act include:

• Sagging ride height or the car sitting uneven
• Bottoming out over speed humps or sharp dips
• Clunks or twangs as the suspension compresses
• Uneven tyre wear and vague steering
• Visible cracks, broken coils, or heavy rust/flaking paint
• Headlights pointing low due to droop

When replacing, do springs in axle pairs to keep handling balanced. It’s smart to inspect the shocks at the same time — tired dampers can kill fresh springs quickly. Replace top mounts, insulators and worn seats, and get a wheel alignment afterward. Critical: torque control arm and bushing fasteners at normal ride height so bushes aren’t preloaded. Spring compressors are no joke, use quality gear or leave it to a pro to avoid damage or injury.

For longevity, rinse away coastal salt and red dust that can trap moisture. Avoid chronic overloading, wagons and utes that tow or carry tools may sag sooner and benefit from load-rated or touring springs. Expect well-treated OE springs to last well past 150,000 km, but inspect at every service or at least annually. Considering a drop? Choose ADR/WOF-compliant lowering springs matched to quality dampers to keep geometry tidy, clearance legal, and the ride friendly to daily driving.

Popular questions about 2012 Holden Commodore coil springs

Does the 2012 Commodore run coil springs or air suspension?
It runs coil springs front and rear. The setup is a MacPherson strut front and independent rear with coils on all standard passenger variants. Any factory air or leaf spring fitment doesn’t apply to 2012 Commodore sedans, Sportwagons or performance trims.

When should coil springs be replaced on a 2012 Commodore?
There’s no fixed kilometre interval. Replace if they’re cracked, sagging, noisy, or the ride height is uneven. Cars that tow, carry heavy loads, or run on rough roads may need springs sooner, many last well beyond 150,000 km with normal use.

Can just one coil spring be changed?
It’s strongly recommended to replace springs in pairs on the same axle. Mixing old and new can upset ride height and handling. After fitment, book an alignment and check related parts like shocks, mounts and insulators.
