Parts for your 2006 Holden Commodore-Coil springs

2006 Holden Commodore coil springs — what they do and when to replace them

Coil springs are absolutely used on the 2006 Holden Commodore sedans and wagons. Early 2006 VZ models and the later-in-2006 VE models both run coil-sprung front MacPherson struts, while sedans use rear independent suspension with coil springs. This is documented in the GM Holden VZ Service Manual (Suspension sections) and the VE Commodore 2006 Engineering/Technical Overview, which list coil springs front and rear for passenger variants. Note: some Holden Ute models of the era used a load-carrying rear leaf spring setup, but the 2006 Commodore sedan/wagon uses coils at both ends.

On a 2006 Commodore, the coil springs carry the vehicle’s weight, set ride height, and work with the shocks to control body movement. They’re key to comfort and handling whether it’s a daily commute or a quick run down a country road. When the springs get tired, the car can sit low, feel floaty, bottom out over bumps, or wear tyres oddly. Broken coil ends (pigtails), rust flaking, or rubber isolators that are perished are all reasons to act.

During regular servicing, it’s smart to have the springs and related bits checked. A good plan is to inspect every 10,000–15,000 km for:

• Ride height changes or a lopsided stance
• Cracks, chipped coating, or heavy corrosion (especially at the ends)
• Damaged top mounts, isolators, bump stops, or noisy spring seats

If replacement’s needed, always do them in axle pairs to keep handling balanced. Match the spring rate and height to the exact model (VZ vs VE, sedan vs wagon, engine and trim level like Omega/Executive/Calais/SS), and any tow or LPG setups. After fitting, get a wheel alignment and check shock absorbers, worn shocks will kill new springs early.

DIYers can swap springs with the right safety gear, but coil compression is risky—use quality compressors and follow torque specs from the Holden workshop manual. Avoid heating or cutting coils, as that weakens the steel and can make the car unsafe and non-compliant. For towing or carrying gear, consider heavy-duty or load-assist coils. Lowered or raised springs are popular, but stick to legal ride-height rules in Australia and NZ, and choose reputable, model-correct kits for the best ride and control.

Popular questions about 2006 Holden Commodore coil springs

How long do coil springs last on a 2006 Commodore?
There’s no fixed change interval. Many last well past 150,000 km, but high loads, rough roads, or coastal corrosion can shorten life. If the car sags, bottoms out, or the coils are cracked or heavily rusty, it’s time to replace. Regular inspections at service time help catch issues early.

Can they be replaced at home?
Yes, with the correct tools and care. You’ll need a proper spring compressor, quality stands, and torque specs. Because compressed coils store a lot of energy, safety is critical. After installation, book a wheel alignment and check shocks and mounts.

Which springs fit my exact 2006 Commodore?
Spring rates and heights differ by series (late VZ vs early VE), body style (sedan vs wagon), engine, and trim. Towing packs and LPG setups may also change specifications. Use the VIN and option codes to select model-correct springs for proper ride height and handling.
