Parts for your 2015 Holden Commodore-Gas struts

2015 Holden Commodore gas struts — what they do and when to replace

Based on technical references, gas struts are relevant and fitted to the 2015 Holden Commodore. The GM Holden VF Series Service/Workshop Manual (Body/Exterior sections) details bonnet (hood) lift support removal and installation for VF models, and the GM Holden Electronic Parts Catalogue lists lift supports for the bonnet on all VF body styles and for the rear tailgate on the VF Sportwagon. Industry catalogues from common OEM suppliers of lift supports also list VF Commodore bonnet and Sportwagon tailgate applications. Note: the VF sedan’s boot lid uses torsion bars rather than gas struts, and the ute tailgate is hinge/torsion-assisted instead of gas-strut supported.

On a 2015 Commodore, gas-charged struts make daily life easier. They safely hold the bonnet up while spannering away and, on Sportwagon models, they control the big rear tailgate so it lifts smoothly and stays put. Each strut is a sealed, nitrogen-filled damper that uses gas pressure and oil to balance weight and movement. They’re maintenance-light, but they don’t last forever—age, temperature swings, and a bit of road grime eventually take the sting out of them.

As part of regular servicing, it’s smart to give the struts a quick once-over. If the bonnet feels heavy, sags in cooler weather, or won’t stay up on a slight slope, the struts are telling you they’re tired. Any oil mist around the rod seal, notchy movement, or pitting on the chrome rod are also solid clues it’s time for new ones. Struts are non-serviceable, so the fix is replacement.

Best practice is to replace in pairs, use OE-spec fitment, and install them rod-end down (that keeps the internal seal lubricated). Don’t grab the polished rod with pliers, don’t spray silicone or grease on it, and always support the bonnet or tailgate with a prop or a mate during the job. Most owners see 5–10 years from a set, but hot summers, coastal air, and frequent use can shorten that. A fresh pair makes a big difference to safety and day-to-day convenience.

• Typical failure signs: bonnet or tailgate dropping, slow lift in cold weather, visible oil at the seal, or uneven/jerky movement.
• Replacement tips: support the panel, swap one side at a time, confirm clip engagement, and cycle the panel a few times to check operation.

For the 2015 VF sedan boot, don’t go hunting for struts—they’re not fitted. If the boot pops weakly, the torsion bars or latch adjustment are the places to look. Sportwagon owners, however, will benefit from fresh tailgate struts when lift effort increases or the gate won’t hold up.

Popular questions

Do all 2015 Commodores have gas struts?

Yes for the bonnet across sedan, Sportwagon, and ute. The Sportwagon also uses gas struts on the rear tailgate. The sedan boot uses torsion bars (no gas struts), and the ute tailgate is hinge/torsion-assisted.

How long do gas struts last and should they be replaced in pairs?

Typically 5–10 years, depending on climate and use. Always replace in pairs for even lift and to avoid overloading a single new strut.

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

Automotive bonnet and tailgate struts are sealed units and aren’t designed for re-gassing. Replacement with quality, correct-spec struts is the reliable, safe fix.
