Parts for your 2017 Holden Commodore-Gas struts

2017 Holden Commodore gas struts — what’s fitted and how to look after them

Based on technical references like the Holden VF Series II Body Service Manual and the Holden Electronic Parts Catalogue (EPC) for 2017 models, gas struts are fitted to the rear tailgate of the 2017 Holden Commodore Sportwagon (left and right lift supports). The same sources show the sedan’s boot uses torsion bars (not gas struts), and the bonnet across sedan, wagon and ute uses a prop rod as standard equipment. Aftermarket catalogues from major lift-support makers also list tailgate struts for the VF Sportwagon, with bonnet struts offered only as retrofit kits. So, gas struts are absolutely relevant for Sportwagon owners, while sedan owners will mainly encounter them only if a previous owner has added bonnet struts.

On the Sportwagon, the gas struts do the heavy lifting: they counterbalance the tailgate so it opens smoothly and stays put overhead. When they’re healthy, the tailgate feels light, controlled and safe. As they age, internal pressure drops and seals can weep, which is why a once-effortless lift can suddenly feel sluggish or the tailgate might nudge down on a windy day. That’s the cue to get them checked and replaced.

As part of routine servicing, it’s smart to do a quick lift-support check. Open the tailgate, listen for creaks or a hiss, and watch for any hesitation or droop. A light oil film on the shaft can point to seal wear. In cooler New Zealand and Australian winters, weak struts show up faster, so a seasonal check doesn’t hurt. When replacement time comes, go for OE-spec or quality aftermarket units with the correct Newton rating, and replace them as a pair so the lift and latch alignment stay consistent.

• Always support the tailgate with a prop or helper before unclipping a strut.
• Don’t grease the shiny shaft—just keep it clean and free of grit.
• Inspect ball studs and retaining clips, replace any bent or corroded hardware.
• Expect service life of around 5–8 years depending on use and climate.
• Dispose of old struts safely—they’re pressurised components.

For sedans, because the boot uses torsion bars, there’s no gas-strut maintenance to schedule. If bonnet gas struts have been retrofitted, treat them like the wagon’s tailgate units and inspect them at each service.

Popular questions about 2017 Holden Commodore gas struts

Which 2017 Commodore models actually have gas struts?
Sportwagon models have gas struts on the rear tailgate. The sedan’s boot uses torsion bars, and the bonnet on sedan, wagon and ute uses a prop rod unless someone has fitted an aftermarket strut kit.

How long do tailgate struts last, and should they be replaced in pairs?
Typically 5–8 years in local conditions. They weaken gradually, and cold weather shows it up sooner. Replace them as a pair so lift effort, latch alignment and tailgate balance stay even.

Can these be a DIY job?
Yes, with care. Support the tailgate securely, pop off the retaining clips, and swap one side at a time. No special tools beyond a small flat screwdriver are usually needed. If hinges or studs are worn, consider workshop help.
