Parts for your 1990 Suzuki Swift-Gas struts

1990 Suzuki Swift gas struts — what they do and when to replace them

Gas struts are relevant to the 1990 Suzuki Swift hatchback. Technical documentation identifies gas‑charged “back door stays” (lift supports) on the hatch, while the bonnet uses a manual prop rod. Sedan variants typically use torsion bars or conventional hinges for the boot, not gas struts. This is supported by factory and service literature, including: Suzuki Swift (late 1980s–early 1990s) Service Manual – Body section “Back Door/Back Door Stay”, Suzuki Electronic Parts Catalogue listings for “Stay, back door” on Swift hatch models of the period, and general repair manuals (Haynes/Gregory’s) that cover tailgate/liftgate strut removal and refit on Swift/Metro/Cultus hatchbacks.

On a 1990 Swift hatch, the gas struts exist to hold the tailgate safely open and make lifting it a breeze. Over time, the nitrogen charge and internal seals fade, and the hatch can drop or feel heavy — not ideal when loading the groceries or the footy gear. As part of regular servicing, it’s smart to check the hatch opens smoothly, holds at full height, and doesn’t sag in wind or cold weather. If there’s any hesitation or bounce, or if one side looks oily, the struts are likely due.

Replacement is straightforward but should be done safely. Always support the hatch with a prop or a helper before popping the clips. Swapping struts in pairs keeps the lift even and helps them last longer. Avoid gripping the shiny rod with pliers — any nick ruins the seal. Don’t grease the rod, just keep it clean and free of grit. A quick wipe with a soft cloth during washes is enough. While you’re there, check hinge bolts, the hatch alignment, and the weatherstrip for water leaks.

Quality aftermarket gas struts are readily available across Australia and New Zealand for the 1990 Swift hatch, and most come with new clips. Fitment usually takes 10–20 minutes. If the bonnet feels heavy, that’s normal — it’s designed to use the factory prop rod, and retrofitting bonnet gas struts needs brackets not supplied by Suzuki. Owners of sedan models shouldn’t expect boot gas struts from factory, they typically use torsion assistance, so there’s nothing to replace unless upgrading.

Popular questions

How long do 1990 Swift hatch gas struts usually last?
In local conditions, anywhere from 5–10 years is typical, but age, heat, and how often the hatch is used all play a part. If the hatch won’t stay up in cooler mornings or drops suddenly, it’s time to replace them.

Can the bonnet on a 1990 Swift be converted to gas struts?
Yes, but it’s a retrofit. The bonnet is factory‑supported by a prop rod. Aftermarket kits exist, though they require specific brackets and careful placement to avoid panel damage. It’s not a factory part on this model.

Do 1990 Swift sedans have gas struts on the boot?
Generally no. Most sedans of this era use torsion bars or spring‑assisted hinges. If the boot feels heavy, checking hinge condition and torsion assist is the first step rather than looking for gas struts.
