Parts for your 2013 Suzuki Sx4-Gas struts

2013 Suzuki SX4 Gas Struts — What They Do and When to Replace Them

Technical sources confirm gas struts are used on the 2013 Suzuki SX4 hatch’s tailgate. The Suzuki SX4 Service/Workshop Manual (Body/Exterior – Liftgate/Rear Door section) specifies gas‑charged support dampers for the rear hatch, while the bonnet is supported by a stay rod (not gas struts). The Suzuki Electronic Parts Catalogue (EPC) for the 2013 SX4 hatch also lists liftgate support dampers as standard fitment. On sedan variants, the boot lid typically uses torsion bars rather than gas struts.

For the 2013 SX4 hatch, these gas struts make life easier by safely holding the tailgate open and giving a smooth, controlled lift and close. They’re nitrogen‑charged dampers that counter the weight of the tailgate, so there’s no need to shoulder it or prop it up with a bit of timber. When they’re healthy, the tailgate should rise cleanly and stay put, even on a breezy day at the beach or when loading the weekly shop.

There’s no fixed replacement interval, but they’re a wear item. Signs they’re fading include the tailgate dropping or needing a helping hand to open, slow or jerky operation (often worse on cold mornings), oily residue on the shaft, or a faint hiss and weak resistance. If one strut is tired, the other won’t be far behind, so replacement in pairs is the go for balanced support.

Good workshop practice for an SX4 service includes a quick function check of the tailgate: open fully, observe for smooth movement, and confirm it holds at full extension. If replacement is due, support the tailgate with a prop or an extra set of hands. Pop the retaining clips at the ball sockets with a small flat screwdriver, swap the struts, and click them onto clean ball studs. Don’t twist the rod, don’t clamp the shaft, and never lubricate the shiny shaft—grease attracts grit and chews out the seals. A light silicone wipe on the plastic end fittings is fine, keep the shaft itself clean and dry.

After fitting, cycle the tailgate a few times to settle the joints and check the latch alignment, hinges, and weatherstrip. In colder climates across Australia and New Zealand, slight stiffness on first lift is normal, but a tailgate that won’t stay up needs attention straight away.

• Replace in pairs for even support
• Support the tailgate during removal/installation
• Keep the strut shaft clean and dry, do not lubricate
• Dispose of old struts responsibly (they’re gas‑charged)

How long do the 2013 Suzuki SX4 tailgate gas struts usually last?

In typical Aus/NZ conditions, owners commonly see 5–10 years, depending on use, heat, dust, and how often the tailgate is cycled. Coastal exposure and frequent loading can shorten life.

Rather than a set kilometre limit, go by symptoms: if the tailgate sags, opens slowly in the cold, or leaves a light oil film on the shaft, it’s time to replace.

Can the SX4 bonnet be converted to gas struts?

The factory setup uses a bonnet stay rod. Aftermarket bonnet strut kits exist for some markets, but they’re not OEM. If fitting a kit, ensure brackets pick up strong mounting points and don’t foul the bonnet, guard, or wiper cowl.

Any modification should be reversible and use corrosion‑resistant hardware. Recheck panel gaps and bonnet latch operation after installation.

Why do the tailgate struts feel weaker in winter?

Gas pressure and fluid viscosity change with temperature. On chilly mornings they’ll feel a bit lazier, which can be normal. But if the gate won’t hold itself up, the struts are below spec and should be replaced.

Regular function checks at service time help catch marginal struts before they become a safety risk.
