Parts for your 2015 Honda Civic-Gas struts

2015 Honda Civic gas struts: what’s fitted and what to service

Based on Honda service literature for the 9th‑gen Civic (2012–2015) and OEM parts catalogues used in Australia and New Zealand, gas struts are factory‑fitted on the 2015 Honda Civic Hatch (FK) to support the rear tailgate. The 2015 Civic Sedan and Coupe use torsion bars for the boot and a manual prop rod for the bonnet, with no factory gas struts in those positions. Owner’s manuals and parts diagrams for the AU/NZ hatch specifically list gas‑filled tailgate supports, while sedan/coupe diagrams list torsion springs and a bonnet prop rod. Aftermarket bonnet‑strut kits exist, but they’re not OEM.

For Civic Hatch owners, the tailgate gas struts do the heavy lifting—literally. They’re sealed, nitrogen‑charged springs that counterbalance the hatch, making it easy to lift and keeping it safely propped open. Over time, seals wear and pressure drops, especially with heat, cold, or frequent use. When that happens, the hatch can feel lazy, not hold at full height, or even drift down—none of which is ideal on a windy day at the shops.

There’s no fixed service interval, but it’s smart to check operation at every service. If the hatch won’t stay up, needs two hands to raise, or you hear a faint hiss and see oil mist around the shaft, it’s time for new struts. Replace them in pairs so lift and hold are balanced.

• Safety first: support the hatch with a prop or a helper before removing any strut.
• Most Civic Hatch struts use ball‑socket clips—pop the clip, ease the joint off, swap the strut, and click it home.
• Fit with the rod (chrome shaft) pointing down where applicable, it helps internal lubrication and seal life.
• Don’t grease the shaft—keep it clean and dry. Wipe off dirt with a soft cloth.
• Expect temperature effects: struts feel stronger in summer and weaker in winter.

If you’ve got a 2015 Civic Sedan or Coupe, you won’t find factory gas struts on the boot or bonnet. The boot torsion bars and bonnet prop are simple, reliable, and light—one reason Honda didn’t spec gas struts there. If you’re keen on a one‑hand bonnet lift, quality aftermarket kits are available, just stick to reputable brands and follow torque specs.

FAQs

Do all 2015 Honda Civics have gas struts?
No. The 2015 Civic Hatch has gas struts on the tailgate. The Sedan and Coupe use torsion bars for the boot and a bonnet prop rod, with no factory gas struts in those locations. Aftermarket bonnet‑strut kits can be fitted if desired.

How long do tailgate gas struts last on a 2015 Civic Hatch?
Typically 5–10 years, depending on climate and use. Replace when the hatch won’t stay up, lifts sluggishly, or shows oil mist around the shaft. Always replace in pairs for even performance.

Can 2015 Civic gas struts be re‑gassed?
Most automotive gas springs are sealed and not designed for re‑gassing. The usual fix is replacement. Some specialists can re‑gas certain types, but availability and results vary, new matched struts are the straightforward option.
