Parts for your 2017 Holden Astra-Gas struts

2017 Holden Astra gas struts

Technical sources indicate gas struts are fitted to the 2017 Holden Astra hatch (BK/Opel Astra K) for the tailgate, while the bonnet uses a manual prop rod and the Astra sedan’s boot uses torsion bars rather than gas struts. References include the GM Global EPC for BK Astra MY2017 (tailgate gas spring listed for hatch variants, e.g., GM p/n 13412667), the Holden/GM Service Manual (Body – Rear End – Tailgate Gas Spring removal/installation), and major catalogues from Stabilus and Monroe showing hatch lift supports for 2017 Astra BK and torsion-rod boot supports for the sedan. So, gas struts are relevant for the hatch tailgate, not the bonnet or the sedan’s boot.

On the 2017 Holden Astra hatch, gas struts keep the tailgate lifting smoothly and staying put overhead, so loading the weekly shop or the pram isn’t a shoulder workout. A matched pair of pressurised struts supports the tailgate weight, controls opening speed, and resists bounce on rough roads. They also help protect hinges and latches by taking the load evenly.

As these struts age, nitrogen charge and internal seals can fade. Owners may notice the tailgate opening slower, dropping the last few centimetres, or refusing to stay up on cold mornings. That’s the cue to replace them. Service practice is to swap both sides together to maintain balance and factory lift force.

During routine servicing it’s smart to give the gas struts a quick once‑over:

• Check for oily film on the shaft or body (seal weep).
• Listen for creaks or binding at the ball sockets.
• Confirm the tailgate stays up through the full stroke in cold and hot weather.
• Inspect mounting studs and clips for play or corrosion.

Replacement is a simple job with the right support stick. Secure the tailgate, pop off the retaining clips, and transfer any end fittings. Avoid twisting the rod, and never clamp the chrome shaft with pliers. Lightly grease the ball studs only, keep lubricant off the shaft to protect the seals.

Choosing parts matters. Go for OE or reputable aftermarket units with the correct Newton rating, length, and end type for the BK hatch. Fresh struts should lift cleanly without slamming and hold the tailgate steady on an incline. For longevity, keep grime off the shafts, don’t force the tailgate against an obstruction, and replace tired bonnet prop grommets so the hatch doesn’t get slammed as a workaround.

There’s no fixed replacement interval, but many city cars see five to eight years before noticeable fade, sooner in coastal areas. Cold snaps can expose marginal struts because gas pressure drops with temperature. If it holds in summer but not winter, it’s time. If the Astra runs a heavier aftermarket spoiler, specify uprated struts to suit. Old units are pressurised, treat them as hazardous scrap and recycle appropriately.

Does the 2017 Holden Astra have bonnet gas struts?

No. The BK Astra uses a manual bonnet prop from factory. Aftermarket bonnet strut kits exist, but owners should pick vehicle‑specific hardware and check clearance with the bonnet, hinges, and washer lines. Any retrofit should avoid drilling into structural areas and must not foul the bonnet at full lift.

How long do tailgate gas struts last on a 2017 Astra?

Typically five to eight years, depending on use, climate, and exposure. Signs they’re due include a tailgate that won’t stay up, slow or uneven lift, or a light oil mist on the shaft. Best practice is to replace in pairs so the opening force and holding power match.

Are hatch and sedan gas struts the same on 2017 Astra models?

No. The BK hatch uses gas struts on the tailgate, while the sedan’s boot uses torsion bars and doesn’t have gas struts. Within hatch trims (R, RS, RS-V) the struts are generally the same spec, but cars with heavier spoilers may require uprated units—check the part number and Newton rating.
