Parts for your 2011 Holden Commodore-Gas struts

2011 Holden Commodore gas struts

Technical references including the Holden VE Series II Workshop Manual and GM Global EPC, plus application catalogues from Stabilus Lift-O-Mat and Monroe Max-Lift, show that the 2011 Holden Commodore range does use gas-charged lift supports — specifically on the Sportwagon tailgate and on some dealer/accessory hard tonneau or canopy lids. From factory, the sedan’s boot uses torsion-rod gooseneck hinges and the bonnet is held up by a prop rod, so bonnet and sedan-boot gas struts aren’t applicable in OE form. That means gas struts are highly relevant for Sportwagon owners and anyone with a strut-supported accessory lid.

On vehicles fitted with them, gas struts take the heavy lifting out of opening and holding the tailgate (or tonneau) up. They use pressurised nitrogen and internal valving to give a smooth, controlled lift and a stable hold at full height — no more wrestling the tailgate on a windy day or worrying about it dropping on your head.

As part of routine servicing, it’s smart to give the struts a quick once-over. Wipe the rods clean with a soft cloth, check the end fittings and mounting ball studs, and make sure the tailgate rises confidently without help. Cold mornings, heat, age and dust can all knock the stuffing out of a strut, so they’re consumable items over time.

• Signs they’re due: the tailgate sags or won’t stay up, needs a shove to start moving, opens fine when hot but struggles in the cold, or shows oil misting/rod scoring.
• Replacement tips: always change struts in pairs to keep lift balanced, support the tailgate safely, don’t clamp or scratch the rod, click the sockets fully onto clean ball studs, avoid greasing the rod (it attracts grit).

Most owners will see 5–10 years from a quality set, depending on climate and use. If you’re loading bikes, prams or groceries often, that extra cycle count can shorten life a touch. There’s no real “service” beyond inspection — when they’re weak, swapping them is the cure. The good news: the job is quick, requires basic tools, and brings the car back to feeling tidy and safe to use. For Sportwagon drivers, fresh struts make the tailgate pop up neatly and stay put, which is exactly how Holden intended.

Popular questions

Do all 2011 Holden Commodores have gas struts?
Not all. Factory-fit gas struts are on the VE Series II Sportwagon tailgate and on certain accessory tonneau/canopy lids. The sedan’s boot uses torsion-rod hinges and the bonnet has a prop rod from new.

How often should gas struts be replaced?
There isn’t a fixed interval. Inspect them at regular services, most last 5–10 years. Replace when the tailgate sags, needs help to lift, or you see oil weeping or rod damage.

Can just one strut be replaced?
It’s best to replace in pairs. A single new strut can twist the tailgate, stress hinges and won’t restore even lift and hold. Pairing keeps things balanced and safe.
