1989 Suzuki Swift Gas Struts — What They Do and How to Look After Them

Based on technical references including the Suzuki Swift/Cultus factory service manual (Body section, 1988–1991), the Suzuki Electronic Parts Catalogue (Group 8 Body, Back Door), and common aftermarket application guides (e.g., Stabilus Lift-O-Mat and Monroe Max-Lift listings), the 1989 Suzuki Swift hatchback is fitted with gas struts (liftgate stays) on the rear hatch. The bonnet typically uses a manual prop rod, and sedan variants generally use torsion bars on the boot lid rather than gas struts. So for a 1989 Swift hatch, gas struts are absolutely relevant—just not for the bonnet.

On the Swift hatch, gas struts support and smoothly control the liftgate so it opens easily and stays put while loading up the groceries or tools. They’re sealed, nitrogen-charged units that provide consistent lift assistance and damping, making the back door feel light and secure.

Telltale signs they’re on the way out include a hatch that sags or won’t stay up, slow or uneven lifting, a need to help it open by hand, or oily film on the piston rod. Cooler weather often makes weak struts feel worse. If any of that sounds familiar, it’s time to replace them.

Replacement is straightforward but should be done safely. Support the hatch with a prop or helper, then swap the struts one at a time. Replace in pairs so lift and hold are even left-to-right. Choose struts with the correct length, end fittings, and force rating (usually specified in newtons for the Swift’s tailgate). Don’t lubricate the shiny piston rod—oils can damage the internal seals. If the original clips are tired or bent, fit new ones with the new struts.

Maintenance is minimal: keep the rod clean with a dry microfibre cloth and avoid paint, silicone, or grease on the rod. During regular servicing (say every 12 months), give the hatch action a quick check—does it open with confidence and hold at full height? For cars with spoilers or heavier accessories on the hatch, expect a shorter service life or consider uprated struts. While some local re-gassing services exist in Aus and NZ, many Swift struts are crimped and are more economical to replace than re-gas.

• Note: Hatch = gas struts, Bonnet = prop rod, Sedan boot = torsion bars (no gas struts).

Popular questions about 1989 Suzuki Swift gas struts

Do all 1989 Suzuki Swifts use gas struts?
Hatchbacks do, on the rear liftgate. The bonnet usually uses a prop rod, and most sedans use torsion bars on the boot lid, not gas struts. If it’s a hatch, it’ll have a pair of gas struts on the back door.

How long should the hatch gas struts last?
Anywhere from 5–10 years is common, but age, heat, cold, and how often the hatch is used all play a part. If the hatch won’t stay up, rises sluggishly, or needs a hand to open, they’ve reached the end of their service life.

Can the original Swift gas struts be re-gassed?
Some providers in Australia and New Zealand offer re-gassing, but many OE-style units are crimped. For most owners, fitting new replacement struts with the correct length and force is the quicker, more reliable, and often cheaper option.
