Parts for your 2009 Mazda Premacy-Gas struts

2009 Mazda Premacy gas struts — purpose, care and replacement

Based on the Mazda Premacy (CR) workshop manual for Body and Doors/Liftgate, the Mazda electronic parts catalogue (EPC) for 2005–2010 CR models, and aftermarket application catalogues from well-known lift-support makers (e.g., Stabilus “LIFT-O-MAT” and Monroe Max-Lift), the 2009 Mazda Premacy is factory-fitted with two gas-charged struts on the rear liftgate. The bonnet on this model uses a prop rod rather than gas struts from factory.

On a 2009 Mazda Premacy, the rear gas struts do the heavy lifting. These nitrogen-charged dampers balance the weight of the tailgate, letting it open smoothly and stay put without a shoulder workout. They also prevent the hatch from dropping onto heads or groceries — a simple part doing a big safety job.

Like any pressurised component, gas struts slowly lose charge. Owners will usually notice the hatch rising sluggishly, needing a hand to start moving, or refusing to stay up — especially on a chilly morning. A light oil mist around the shaft, squeaks, or visible scoring are other giveaway signs.

Good servicing habits keep them sweet:

• Give the chromed shafts a quick wipe with a clean, dry cloth every few months — keep grit off the seals.
• Avoid spraying silicone, grease, or solvent on the shafts, it can swell seals and shorten their life.
• Check operation seasonally. Cold temps expose weak struts, so test on a cool morning.

When it’s time to replace, it’s best practice to do them in pairs to keep lift and damping balanced. The job is a straightforward driveway task: support the hatch safely (a mate or a prop), gently flick up each strut’s locking clip with a small flat screwdriver, pop the ends off the ball studs, then clip the new ones on. Fit them with the rod pointing down where applicable, it keeps internal seals lubricated. Expect about 10–20 minutes with basic tools.

Quality aftermarket units matched to the CR Premacy’s liftgate make a noticeable difference in everyday use. After fitting, cycle the hatch a few times to seat the joints, listen for clicks or binding, and confirm the gate holds at full height. Dispose of old struts responsibly — they’re pressurised, so don’t puncture or burn them.

FAQs

Do 2009 Mazda Premacy bonnets have gas struts?
No. The CR-series Premacy (2005–2010) uses a bonnet prop rod from factory per Mazda workshop documentation. Aftermarket bonnet strut kits exist, but they’re not original equipment, and fit/clearance should be checked carefully before installing.

How long do Premacy liftgate gas struts last?
Typically 5–8 years, depending on use and climate. Frequent opening, hot summers, and coastal environments can shorten life. A quick annual function check during servicing is a smart way to catch weak struts before the hatch starts sagging.

Can just one strut be replaced?
It’s technically possible, but replacing in pairs is recommended. Mismatched force can twist the hatch, stress hinges, and feel odd in use. Pair replacement restores balanced lift and consistent damping on both sides.
