Parts for your 2005 Holden Commodore-Coil springs

2005 Holden Commodore Coil Springs

Coil springs are absolutely relevant to the 2005 Holden Commodore (VZ). Holden service manuals and parts catalogues for the VZ series specify MacPherson strut front suspension with coil springs across the range, and rear coil springs on sedans and wagons (IRS or live-axle variants). Note: many VZ Utes use leaf springs at the rear for load carrying, but still run a coil-sprung front end. For a 2005 Commodore sedan or wagon, coil springs are fitted front and rear.

On a VZ Commodore, coil springs support the vehicle’s weight, set the ride height, and work with the shocks to keep the tyres planted over bumps. When the springs are healthy, the car sits level, rides comfortably, and steers predictably. As they age, coils can sag, crack, or lose tension, which drops ride height and upsets alignment and braking stability. Drivers might notice a nose-down stance, a “boaty” feel over undulations, or clunks from a broken coil end.

There’s no fixed kilometre interval to replace coil springs, they’re changed on condition. It’s smart to have them inspected during regular servicing, especially if the car tows, carries loads, or runs on rough roads. A technician will check ride height, spring condition (rust, chips, cracks), and the rubber isolators. Any visible break, severe pitting, or uneven ride height means it’s time to replace.

When replacement’s due, do both sides on the same axle to keep handling balanced. Pairing fresh springs with good shocks is ideal—tired dampers can make new springs feel bouncy. Choose springs that match how the Commodore is used: OE-equivalent for factory comfort, heavy-duty for towing, or quality lowered springs if a sportier stance is wanted. Avoid ultra-cheap options that can sag quickly or ride harshly.

• Always use proper spring compressors—coils store serious energy. Leave it to a pro if unsure.
• Replace related bits while you’re in there: strut mounts/bearings, bump stops, and rubber isolators.
• Finish with a wheel alignment, small height changes alter camber and toe, and can chew tyres.
• For VZ Utes, remember the rear may be leaf-sprung—order parts by VIN to avoid mix-ups.

Looked after properly, quality coil springs will keep a 2005 Commodore riding level and feeling spot-on for many years and kilometres.

Popular questions about 2005 Holden Commodore coil springs

How can someone tell if their 2005 Commodore’s coil springs are worn out?
Typical giveaways are a sagging or uneven ride height, knocking noises over bumps, and a floaty or crashy feel on rough roads. Uneven tyre wear can also creep in because the alignment drifts as springs settle. A quick height check from hub centre to guard on both sides will often reveal a low corner. If there’s any sign of a cracked coil or chipped ends, it’s replacement time.

Can coil springs be replaced at home?
It’s doable with the right tools and know-how, but coil springs are under a lot of tension. Quality spring compressors, safe jacking points, and torque specs are essential. Most owners prefer a workshop to handle it, especially for front struts on the VZ. Either way, plan on a wheel alignment after the job.

Should shocks be replaced with the springs?
Not mandatory, but it’s good practice. New springs paired with tired shocks can leave the car bouncy or under-damped. If shocks have weeped, feel soft, or have clocked big kilometres, replacing them with the springs restores proper control and protects the new coils from overworking.
