Parts for your 2009 Holden Commodore-Gas struts

2009 Holden Commodore gas struts — what they do and when to replace them

Yes, gas struts are relevant on a 2009 Holden Commodore (VE series). Factory documentation backs this up: the Holden/GM VE Service Manual covers “Rear Compartment Lid Support Strut — Removal and Installation” for the sedan and “Liftgate Support Strut — Replacement” for the Sportwagon, while the bonnet is shown with a support rod rather than gas struts. GM Holden’s Electronic Parts Catalogue for VE also lists dedicated struts for the boot (sedan) and liftgate (Sportwagon), along with the ball-stud hardware. So, if it’s a VE sedan or Sportwagon, it’ll have gas struts at the back, the bonnet runs a prop rod unless someone’s fitted an aftermarket kit. Ute hard lids typically use gas struts too if so equipped.

On the Commodore, gas struts do the heavy lifting for the boot or tailgate, controlling the rise and helping keep it held up safely. Over time they lose pressure, making the lid slow to open, saggy, or outright unwilling to stay up — not ideal on a windy day at the shops. As part of regular servicing, it’s smart to check how positively the lid lifts and holds, and to look for a light oil mist on the strut body, rusty ball studs, or damaged end fittings.

When it’s time to replace, swap them in pairs so both sides share the load evenly. Support the boot or tailgate with a prop, then flick the spring clip at each end of the strut and pull it off the ball stud. Don’t pry on the rod and never clamp the shaft with pliers. New struts usually snap straight on, ensure the clip is fully seated and the rod faces shaft-down when possible for best seal lubrication.

Maintenance is low-fuss: keep the chrome shaft clean and dry, and avoid grease on the shaft (it attracts grit and chews out the seals). A light silicone on the ball studs only is fine. Temperature swings can change how lively they feel — a cold morning will make tired struts feel even lazier — so judge performance across normal use. If the lid won’t stay open or the lift is uneven, don’t muck about, fit new ones. Correct lengths and force ratings vary by body style and trim, so match to the VIN or OE part number from the Holden catalogue or a reputable supplier.

• Common signs they’re due: slow or jerky opening, lid drops or won’t hold, visible oil film, knocking at the hinge line.
• Safety tip: always support the lid during inspection or replacement.

How long do boot or tailgate gas struts last on a 2009 Commodore?

Anywhere from 5–10 years is pretty normal, but climate, mileage, and how often the boot or tailgate is used make a big difference. If they’re original on a 2009 car, they’ve likely had a solid innings. Replace in pairs for even support and better longevity.

Are bonnet gas struts standard on a 2009 Commodore?

No — from factory the VE bonnet uses a prop rod. Aftermarket bonnet strut kits are popular, but they’re not OE. If adding a kit, choose brackets that mount to existing points and struts with suitable force so the bonnet opens smoothly without stressing the hinges.

Can gas struts be re-gassed, or should they just be replaced?

Most OE-style automotive struts are sealed and not designed to be re-gassed. The practical fix is replacement. New units are affordable, quick to fit, and restore full lift and hold. Re-gassing services exist in niche cases, but for Commodore owners, new struts are the straightforward option.
