Parts for your 2015 Ford Focus-Gas struts

2015 Ford Focus gas-struts: what they do and when to replace them

Technical sources including the Ford Workshop Manual (Body and Paint, section 501) and major gas-spring catalogues from Stabilus (LIFT-O-MAT) and Monroe (Max-Lift) confirm the 2015 Ford Focus hatchback is fitted with gas-charged lift supports on the tailgate. The bonnet on this model generally uses a prop rod rather than gas struts, and many sedans use torsion bars for the boot lid. So, for hatch owners in particular, gas-struts are absolutely relevant service items on a 2015 Focus.

On a 2015 Focus hatch, the gas-struts do the heavy lifting for the tailgate, making it easy to open and keeping it safely up while loading shopping, prams, or tools. Each strut is a sealed, nitrogen-charged unit with internal oil for damping. As pressure fades over time, they lose the oomph to hold the hatch high—most noticeable on cold mornings.

There’s no fixed replacement interval, but five to ten years is common for service life. For a 2015 car, a fresh set is often due. As part of regular servicing—say, at each WOF or rego check—give the struts a quick once-over. Make sure the hatch lifts smoothly without help, doesn’t sag, and stays fully up without creeping down. Wipe the shiny shafts with a soft cloth and keep grit away from the seals. Don’t lubricate the shafts, oil or grease can damage the seals.

When it’s time to replace, do both sides together to keep the lift even. Support the hatch securely with a prop or a helper—those last few millimetres of pressure can surprise. Swap one strut at a time, clip-on/ball-stud style, and orient the body of the strut upwards (rod down) unless the manufacturer specifies otherwise—this keeps the internal seal bathed in oil. If your Focus has a spoiler or accessory glass, choose struts with the correct force rating, catalogues list variants for different tailgate weights.

Handy signs they’re on the way out:

• The hatch needs a shove to start rising, or won’t stay up.
• It lifts fine in the arvo but droops in the morning chill.
• Visible oil film on a shaft, bent hardware, or popping/creaking at the ball joints.

Once fitted, check the ball studs for play, confirm smooth motion through the full arc, and recycle old units responsibly. That’s one small job that makes the Focus feel brand new again.

Popular questions

Are gas-struts standard on all 2015 Ford Focus models?
Most 2015 Focus hatchbacks have gas-struts on the tailgate. The bonnet typically uses a prop rod, and many sedans use torsion bars for the boot instead of gas-struts. Aftermarket kits are available if someone wants bonnet struts.

How long do Focus gas-struts last, and when should they be replaced?
Expect around 5–10 years depending on climate and usage. Replace when the hatch won’t stay up, lifts slowly, or needs help to open—especially if symptoms worsen in cold weather. Always replace in pairs.

Can gas-struts be re-gassed, or should they be replaced?
Most automotive struts are sealed units, re-gassing isn’t practical or reliable for everyday use. Replacement with quality, correctly rated struts is the usual and cost-effective fix.
