Parts for your 2022 Mazda Cx-5-Gas struts

2022 Mazda CX-5 gas struts — what they do and when to replace them

Based on Mazda technical references — the CX‑5 (KF) Workshop Manual (Body: Liftgate, Stay Damper), the 2022 CX‑5 Owner’s Manual sections covering the tailgate/power liftgate, and Mazda Genuine Parts catalogue entries for the KF series liftgate stay/damper — gas struts are fitted to the rear liftgate of the 2022 Mazda CX‑5 (on both manual and power tailgate variants). The bonnet on this model uses a prop rod rather than gas struts, so the relevant gas-strut application here is the tailgate.

The gas struts on a 2022 Mazda CX‑5 do the heavy lifting behind the scenes. Charged with nitrogen and a dab of oil for damping, they counterbalance the weight of the tailgate so it opens smoothly and stays put overhead. Even on power liftgate trims, the electric actuator works with these struts — the motor manages motion and latching, while the gas struts provide the bulk of the lift and hold. When they’re healthy, owners get a light, predictable lift and confident hold, even with an armful of shopping or the pram.

As with any wear item, gas struts lose pressure over time, especially with heat, dust, and plenty of open/close cycles common in Aussie and Kiwi daily driving. During routine servicing, it’s smart to give them a quick once-over.

• Watch for these signs: tailgate feels heavy or needs a helping hand to start moving, it won’t stay up reliably, there’s a slow rise in cooler weather, or an oily film appears on the rod.
• Servicing tips: keep the chrome rod clean and dry (no grease or silicone on the shaft), check the ball-studs and retaining clips for play or corrosion, and replace struts in pairs to keep lift balanced.

Replacement is straightforward but safety matters. The tailgate must be safely supported — a second person or a prop is a must. Each strut typically uses spring clips at both ends, release, swap, click in, and confirm secure fitment. Always match length, end fittings and force rating to the CX‑5 specification, and never heat, puncture or crush an old strut — it’s pressurised. If the vehicle has the power tailgate, ensure the new struts are compatible with the system so opening speed and latching remain spot on. Done right, fresh gas struts restore that easy, controlled lift owners expect, whether they’re loading up for a weekend away or the school run.

Popular questions about 2022 Mazda CX‑5 gas struts

How long do the tailgate gas struts usually last?
In typical Australian and New Zealand conditions, many last 5–10 years, but heavy use, beach exposure, or high heat can shorten that. If the tailgate won’t stay up or feels heavy, it’s time.

Can manual-tailgate CX‑5s be upgraded to a power liftgate just by changing struts?
No. Power conversions require additional hardware (actuator, control module, wiring, switches) and calibration. Gas struts alone won’t create a power tailgate.

Why does the tailgate drop more in cold weather?
Gas pressure falls as temperature drops, so weak struts show their age in winter first. If it’s noticeably worse in the cold, replacement will restore proper support year-round.
