Parts for your 2012 Holden Commodore-Gas struts

2012 Holden Commodore gas struts: what they do and when to replace them

Yes, gas struts are relevant on the 2012 Holden Commodore. Technical documentation such as the Holden VE Series II Service Manual (Body – Hood/Liftgate sections), the Holden Electronic Parts Catalogue for VE Series II, and application guides from OE suppliers like Stabilus (LIFT-O-MAT) and Monroe (Max-Lift) identify gas-charged support struts for the bonnet across VE Series II models, and for the Sportwagon’s tailgate. The VE sedan’s boot typically uses torsion springs in the hinge (not gas struts), while utes and accessory hard lids may use struts depending on fitment.

On a 2012 Commodore, the gas struts are there to hold the bonnet up safely, and on Sportwagon models to control and support the tailgate. They’re small, sealed cylinders filled with nitrogen and a dab of oil, providing smooth lift and steady damping so panels don’t slam or drift down on a windy day. Over time, seals wear, the gas charge drops, and the strut loses punch—usually first noticed as a bonnet that won’t stay up on cooler mornings or a tailgate that rises sluggishly.

As part of regular servicing, it’s worth checking how confidently the bonnet or tailgate stays at full height. Look for a light oil film around the rod, any nicks on the chrome shaft, or a tell-tale hiss with weak support. If any of these show up, replacement is the go—struts aren’t repairable and come as matched pairs for even support. Most quality replacements clip in with ball sockets, a small flat blade to lift the retaining clip and a steady hand is typically all that’s required. Use a prop or a helper while swapping them, and avoid twisting the rod or getting grease on the shaft, as that can damage the seals.

• Common signs they’re due: panel won’t hold up, slow lift, bump-stop drop near the top, oily residue on the rod, or needing a shoulder to keep it open.
• Good practice: replace in pairs, match length and force ratings to the VIN/body style, and recycle the old units properly.
• Service tip: quick strut check each service interval (or at least annually) keeps surprises out of the equation.

Quality brands that list direct-fit struts for VE Series II help ensure correct force and mounting ends, aligning with Holden’s factory specs noted in the VE Series II body service procedures and parts listings.

Popular questions

How long do gas struts last on a 2012 Commodore?
Typically 5–10 years depending on use, climate, and how often the panel is cycled. Heat, dust, and salty air can shorten life. If the bonnet or Sportwagon tailgate won’t stay up, they’re due regardless of age.

Can just one strut be replaced?
It’s best to replace in pairs. Mixing a tired strut with a fresh one can twist hinges and gives uneven support. Matching pairs keep the panel balanced and extend hinge life.

Are sedan boots supposed to have gas struts?
On VE Series II sedans, the boot uses torsion springs, not gas struts. Sportwagon models use gas struts on the tailgate, and utes or hard lids may use struts depending on the lid kit.
