Parts for your 2017 Subaru Exiga-Gas struts

2017 Subaru Exiga gas struts: what they do and how to keep them working

Yes, gas struts are used on the 2017 Subaru Exiga. Technical sources including the Subaru parts catalogue (Back Door Stay/Gas Stay), Subaru service information for the rear gate gas stay, and aftermarket application guides (e.g., Stabilus Lift-O-Mat and Monroe listings for 2015–2018 Exiga/Exiga Crossover 7) all show gas-filled lift supports on the rear tailgate. The bonnet on this model uses a prop rod rather than gas struts.

On the 2017 Subaru Exiga, the rear tailgate gas struts do the heavy lifting. Charged with nitrogen and damped with oil, they counterbalance the weight of the hatch so it opens smoothly and stays put without a fight. That makes loading the boot safer and easier—no shoulder workout, no hatch dropping on a windy day.

Over time, seals wear and pressure bleeds off. A tired strut won’t hold the gate up, especially in cold weather. As part of regular servicing, it’s worth giving the tailgate a quick health check: does it lift cleanly, pause halfway, or sag? Any oily film on the rod? Any creaks at the ball joints? Catch these early and you’ll avoid bruised forearms and slammed glass.

• Common signs they’re due: hatch drops or won’t hold, slow or jerky lift (worse in winter), hissing, or oil mist on the shaft.
• Service tips: keep the chrome rod clean and dry, don’t lubricate it with grease or silicone—it attracts grit and damages seals.

Replacement is straightforward and usually best done in pairs to keep lift balanced. Always support the tailgate with a prop or a mate before popping the clips. Note the orientation (rod down on most designs), avoid twisting the shaft, and inspect the ball studs and clips—replace any that are worn. Quality OE or equivalent struts are inexpensive insurance, and many sealed types are not intended to be re-gassed, while some specialists can re-gas certain units, replacing with new is typically the more reliable fix.

As a rule of thumb in Aussie and Kiwi conditions, expect 5–8 years of service life, shorter if the Exiga does lots of short trips, lives outdoors, or carries added weight on the tailgate (e.g., accessories). If a service turns up slow lift or a soft hold, plan a pair of new gas struts so the rear hatch remains safe, tidy, and easy to use.

FAQs

How long do 2017 Subaru Exiga tailgate gas struts usually last?
Most owners see around 5–8 years, depending on climate and use. Heat, cold, dust, and frequent opening shorten their life. If the hatch starts to sag or feels lazy, it’s time to replace them.

Can Exiga gas struts be re-gassed, or should they just be replaced?
Many OEM struts are sealed and meant to be replaced. Some local specialists can re-gas certain types, but new quality struts are often the more reliable and cost-effective option with a fresh warranty.

Does the 2017 Exiga bonnet have gas struts?
No. The bonnet uses a prop rod from factory. Only the rear tailgate is fitted with gas struts on this model.
