1986 Suzuki Swift Gas Struts: What They Do and When to Replace Them

Gas struts are absolutely relevant on the 1986 Suzuki Swift hatch. Factory documentation identifies gas-charged “back door stays” for the rear hatch, while the bonnet uses a manual prop rod. Technical sources backing this include the Suzuki Cultus/Swift Factory Service Manual (1983–1988, Body Section: Rear Door/Back Door Stay), the Holden Barina MB/ML (1985–1988) parts catalogue used in Australia and New Zealand listing gas spring stays for the tailgate, and common aftermarket application guides (e.g., Stabilus Lift-O-Mat and Monroe Max-Lift) which both specify lift supports for the Swift/Barina hatch of this era.

On the 1986 Swift, the gas struts support and control the hatch as it opens and closes. They’re nitrogen-charged dampers that hold the tailgate safely overhead, prevent it from crashing down, and make day-to-day use feel light and tidy. Over time, seals wear and pressure drops, especially with heat cycles, coastal air, or frequent use—pretty normal for older Swifts still putting in work around Aotearoa and Australia.

Good struts keep the hatch stable, protect hinges and glass, and reduce the risk of a head knock when loading the weekly shop or tools. Replacement is a quick, driveway-friendly job and is usually done in pairs to keep lift and balance even.

• Tell-tale signs it’s time: the hatch won’t stay up, lifts slowly (worse on cold mornings), drops the last bit of travel, or shows an oily film on the shaft.
• Basic fitting tips: support the hatch with a prop, flick the retaining clips, swap one side at a time, and install with the rod end down where specified by the supplier.
• Maintenance: wipe the shafts with a clean, dry cloth only (no grease), check ball studs and brackets for corrosion or looseness, and keep the hatch hinges lubricated.

For best results, choose struts matched to the Swift’s original extended length and force rating (noted in application guides or stamped in Newtons on many old units). A correct pair will open smoothly and hold confidently at full height. Typical service life varies with climate and use, but many owners see a solid 5–8 years from quality replacements. It’s an inexpensive fix that makes the whole car feel fresher and safer to live with.

Popular questions about 1986 Suzuki Swift gas struts

Do 1986 Suzuki Swifts have bonnet gas struts?
From factory, no. The bonnet uses a prop rod. Gas struts are fitted to the rear hatch only. Some owners add aftermarket bonnet kits, but that’s a custom upgrade rather than original equipment.

Should both hatch struts be replaced at once?
Yes. Replacing in pairs restores balanced lift and even closing effort. Mixing a new strut with a tired one can twist the hatch, stress hinges, and still feel weak in cooler weather.

How do I pick the right replacement struts?
Match the extended length, end fittings, and force rating (Newtons). Application catalogues for the 1986 Swift/Barina list correct specs, and many original struts are stamped with their rating. If the hatch has accessories (spoiler or added weight), choose a force to suit.
