Parts for your 2019 Subaru Impreza-Gas struts

2019 Subaru Impreza gas struts

Gas struts are absolutely relevant to the 2019 Subaru Impreza hatch (5‑door). The 2019 Subaru Impreza Owner’s Manual includes a caution about the rear gate “stays” being gas‑filled and not user‑serviceable, confirming factory‑fitted gas struts on the hatch’s liftgate. The same manual describes the bonnet as supported by a prop rod, not struts. Subaru parts catalogues list “rear gate stay assemblies” for the 5‑door, while the sedan’s boot uses gooseneck/torsion hinges and no gas struts. So: hatch = gas struts on the rear gate, sedan boot and bonnet = no gas struts.

On the hatch, those rear gate gas struts do the heavy lifting—literally. They take the weight of the tailgate, control its speed, and keep it safely held open so loading the weekly shop or sports gear is a breeze. Each strut is a sealed unit with nitrogen gas and oil that works against an internal piston. Over years of use, seals can wear, pressure can drop, and performance tails off, especially in cold weather.

There’s no fixed service interval, but it’s smart to check them during regular servicing or at least annually. Pay attention to how the gate behaves on cooler mornings and windy days. If it rises sluggishly, won’t stay up, or needs a helping hand, the struts are getting tired and should be replaced.

• Typical signs they’re due: the gate sags or drops, slow/uneven lift, hissing noises, oily film on the shaft, or visible corrosion.
• Best practice: replace in pairs to keep lift and damping balanced.

Replacement is straightforward with basic tools. Support the rear gate securely (a helper or prop is essential), then pop off the spring clips at each end and swap the strut. Match the original orientation—most are installed rod‑down to keep the internal seal lubricated. Choose OE or quality equivalent units with the correct force rating for the Impreza hatch. Avoid compressing new struts by hand, don’t grease the chrome shaft (it attracts grit), and keep the rod clean by wiping with a lint‑free, silicone‑free cloth. After fitting, cycle the gate a few times to confirm smooth, even motion and positive hold‑open.

A couple of safety notes: never drill or heat an old strut, it’s pressurised. Dispose of removed units responsibly. And if the rear gate moves unpredictably or struggles to stay up, treat it as a safety issue and sort it promptly—no one enjoys a tailgate on the back of the head.

Popular questions about 2019 Subaru Impreza gas struts

Does the 2019 Impreza sedan have gas struts?
The sedan’s boot uses gooseneck/torsion hinges, not gas struts. The bonnet is held by a prop rod. Only the 5‑door hatch has gas‑filled stays on the rear gate from factory.

How long do the hatch rear gate struts usually last?
Many last 5–8 years, depending on climate and use. Heat, cold, and frequent cycling can shorten life. If the gate won’t stay up or lifts slowly, they’re due for replacement.

Can just one rear gate strut be replaced?
It’s technically possible, but replacing in pairs keeps lift and damping even, reduces stress on hinges, and usually delivers a better, longer‑lasting result.
