Parts for your 2018 Mazda Cx-5-Gas struts

2018 Mazda CX-5 Gas Struts

Technical references including the Mazda CX-5 (KF, 2017–2021) Workshop Manual (Body/Exterior: Liftgate/Back Door – Liftgate Stay Damper), the Mazda Electronic Parts Catalogue, and major aftermarket catalogues such as Stabilus LIFT-O-MAT and Monroe all list gas‑charged stay dampers for the CX‑5’s rear hatch. The bonnet on this model uses a prop rod rather than gas struts. So yes—gas struts are fitted and relevant on the tailgate of the 2018 Mazda CX‑5.

On the 2018 CX‑5, the tailgate gas struts do the heavy lifting—literally. They counterbalance the hatch weight, help it open smoothly, and hold it up safely while loading the boot. When they’re healthy, the tailgate feels light, controlled and predictable, when they’re tired, it sags, opens lazily, or refuses to stay up, which is more than a little annoying and can be dangerous.

As part of routine servicing, it’s worth giving the tailgate stays a quick once‑over. Look for any oil mist on the shaft, bent rods, cracked end fittings, or a hatch that won’t stay at full height. Performance often drops first in cold weather, and on vehicles that spend long days in the Aussie or Kiwi sun. Most sets last 5–8 years depending on use and climate.

• Signs they’re due: tailgate dropping or bouncing, slow lift, squeaks, visible leaks, or the need to “help” it open.
• Replacement tips: always support the tailgate, swap struts in pairs to keep forces even, match OE part numbers or correct Newton rating, especially on power tailgate models, install with the rod shaft pointing down where specified, don’t twist the body during fitment.
• Care pointers: keep the shafts clean and dry, don’t lubricate the chrome rod (oils attract grit and damage seals), check ball studs and brackets for play.

DIY replacement is typically a straightforward clip‑off, clip‑on job with a pick or small flat screwdriver, but a second set of hands makes it safer. Workshops will also inspect hinge alignment and tailgate weight (added accessories like spoilers can matter) and confirm smooth operation after fitment. Choosing quality, vehicle‑specific struts keeps the CX‑5’s boot practical, quiet, and safe to use every day.

Popular questions about 2018 Mazda CX-5 gas struts

How long do the 2018 Mazda CX‑5 tailgate gas struts last?
Most owners see 5–8 years, shorter with heavy use, roof‑rack loads stressing the hatch, or harsh temperature swings. If the hatch won’t stay up or struggles in cold mornings, they’re nearing the end of their service life.

Should they be replaced in pairs?
Yes. Replacing one can leave uneven support and odd hatch motion. A matched pair restores balanced lift and proper latching height.

Are power tailgate models different?
They still use gas struts, but the force rating and brackets are matched to the power mechanism. Use the correct specification to avoid overloading the motor or causing lazy operation.
