Parts for your 2016 Holden Astra-Gas struts

2016 Holden Astra gas struts — what’s fitted and how to look after them

Gas struts are fitted to the 2016 Holden Astra hatch (Astra K/BK). Holden’s/Opel’s 2016 Owner’s Manual for Astra K shows the tailgate supported by two gas‑charged lift supports, while the bonnet uses a manual prop rod. The GM Global Electronic Parts Catalogue (EPC) for BK Astra lists “Liftgate Support Strut, Gas Charged” as standard equipment on the hatch, and GM Service Information (workshop manual) details removal and installation of these tailgate struts. So yes—gas struts are absolutely relevant on the 2016 Astra hatch, they’re not used on the bonnet.

On a 2016 Astra hatch, the gas struts do the heavy lifting for the tailgate. They’re small nitrogen‑charged dampers that counterbalance the weight of the hatch, so it opens smoothly and stays up without fuss. Beyond convenience, they’re a safety item—preventing the boot from dropping onto heads, fingers, or cargo when the weather turns or the car’s on a slope.

As part of regular servicing, it’s smart to check the struts on condition rather than a fixed interval. Most last five to eight years in typical Aussie and Kiwi climates, but coastal air, heat, and lots of boot use can shorten that. Signs they’re tired include the hatch rising slowly or not holding at the top, a sudden drop near the top of travel, oily residue on the rod, a squeak or hiss under load, or needing a hand to lift in colder weather.

A quick bit of care goes a long way. Wipe the chrome rods with a clean, dry cloth and keep grit away from the seals. Don’t spray silicone or grease on the rods—lubricants can attack the seals and kill the gas charge. If a ball stud or hinge creaks, a tiny touch of suitable lubricant on the ball (not the rod) is fine.

Replacement is straightforward but should be done safely. Always support the hatch with a prop or helper. Replace struts in pairs so lift force stays balanced. Most Astra units use a spring clip at each end: pop the clip slightly with a small flat blade, pull the old strut off the ball, then click the new one on and ensure clips are fully seated. Fit with the rod pointing down if specified on the part—this helps internal lubrication. If a ball stud is removed, clean threads and tighten to the manufacturer’s spec. Choose struts by VIN to match force rating and end fittings, avoid “universal” units that can over‑ or under‑assist the hatch.

One last note: the Astra’s bonnet ships with a prop rod. Aftermarket bonnet‑strut kits exist, but they’re a modification—use quality brackets, follow kit instructions, and check clearance with the bonnet closed.

• Replace on condition, typical lifespan 5–8 years
• Swap both sides together for balanced lift
• Keep rods clean, don’t lubricate the rod surface
• Support the hatch during any work

FAQs

How long do the hatch gas struts last on a 2016 Holden Astra?
Most owners see five to eight years, depending on climate and use. Cold snaps, coastal exposure, and frequent heavy boot loads can shorten their life. Replace when the hatch won’t stay up, rises sluggishly, or shows oil weep.

Why does my Astra’s boot drop in cold weather?
Gas pressure drops as temperature falls, so a marginal strut may feel fine in summer and weak in winter. If the boot sags or needs a hand in the cold, it’s a sign the struts are nearing end of life—time to replace the pair.

Can I fit gas struts to the bonnet instead of using the prop rod?
Yes, aftermarket bonnet‑strut kits are available for the Astra K. They’re a bolt‑on mod using brackets at factory points. Choose a reputable kit, follow instructions carefully, and check bonnet clearance after fitting.
