Parts for your 2014 Mazda Cx-9-Gas struts

2014 Mazda CX-9 Gas Struts

Gas struts are absolutely used on the 2014 Mazda CX-9. Mazda’s own workshop manual for the first‑gen CX‑9 (2007–2015) details “liftgate support cylinder” removal and installation, and the Mazda Electronic Parts Catalog lists the liftgate support dampers for this model. Major OE suppliers’ application catalogues (e.g., Stabilus/Monroe) also specify tailgate gas-charged supports for the 2014 CX‑9. The bonnet on this generation typically uses a prop rod rather than gas struts from factory, so the primary gas struts are for the rear liftgate.

On the 2014 CX‑9, the pair of tailgate gas struts do the heavy lifting every time the rear door is opened. They counterbalance the weight of the tailgate, keep it steady at full height, and stop it from thumping down unexpectedly. When they get tired, the tailgate can sag, feel heavy, or refuse to stay up—especially on cold mornings. Replacing worn struts restores easy one-hand operation and brings back that smooth, controlled opening Mazda intended.

As part of regular servicing, these struts deserve a quick check. A workshop or savvy owner can inspect the chrome shafts for pitting or oil film, listen for creaks, and test holding force at full extension. There’s no set kilometre interval, climate and use matter more. In Aussie heat or the chill of a South Island winter, expect a service life typically around 5–10 years. Once performance drops, it’s best practice to replace in pairs so the lift and balance match.

• Common signs they’re due: tailgate drops or won’t stay up, jerky or slow lift, needing two hands, oily residue on the shaft, or weaker performance in cold weather.
• Helpful tips: don’t push on the strut’s chrome shaft, keep it clean from grit, and always support the tailgate during removal.

Replacement is straightforward with basic tools. Most CX‑9 struts use ball-stud sockets with spring clips—carefully flick the clip, pop the old unit off, then snap the new one on. Support the tailgate securely (a mate or a prop), and confirm the new struts match the correct length and force rating for the CX‑9. A fresh pair brings back safe, effortless access to the cargo area and protects hinges, latches, and glass from shock loads.

Popular questions about 2014 Mazda CX‑9 gas struts

How many gas struts are on a 2014 Mazda CX‑9 and where are they?
The 2014 CX‑9 uses two gas struts on the rear liftgate. The bonnet generally uses a manual prop rod on this generation, so the gas-charged units are focused on the tailgate for lifting and holding.

How long do CX‑9 tailgate struts last?
Most last around 5–10 years depending on climate and use. Heat, cold, and frequent loading cycles can shorten lifespan. If the tailgate feels heavy, won’t hold up, or shows oil on the shaft, it’s time to replace.

Can a home mechanic replace the CX‑9 tailgate struts?
Yes. With basic hand tools and proper support of the tailgate, they’re a quick swap. Replace in pairs, avoid touching the chrome shafts, and confirm the new struts match the correct length and force for the CX‑9.
