Parts for your 2012 Subaru Xv-Gas struts

2012 Subaru XV gas struts — what they do and when to sort them out

Gas struts are absolutely relevant on the 2012 Subaru XV. The model runs a pair of gas‑charged stay assemblies on the rear tailgate/hatch to hold it up and control its movement. Subaru’s body service information for the GP‑series XV (2012 launch) specifies gas‑filled rear gate stays, and the Subaru Electronic Parts Catalogue lists “Stay Complete – Rear Gate” as a matched left and right set for this vehicle. Aftermarket technical catalogues from major suppliers also list dedicated lift supports for the 2012 XV. The bonnet, however, uses a simple prop rod from factory rather than gas struts.

On the XV, those rear gas struts do the heavy lifting. They counterbalance the hatch so it pops and stays open smoothly, and they slow the last bit of travel so it doesn’t thump. Each unit is a sealed, nitrogen‑charged cylinder with internal oil and seals. Over time, seals age, gas pressure drops, and performance tails off—especially noticeable on frosty Kiwi mornings or a cold winter’s day in Tassie.

There’s no set service interval, but they’re worth a quick check at every service. Signs they’re on the way out include: the tailgate sagging or dropping, needing two hands to shove it up, a jerky motion, oil misting near the shaft seal, or a faint hiss with little damping.

• Don’t lubricate the chrome shaft—oil and silicone sprays can damage the seals.
• Keep the shafts clean, wipe away grit that can chew out the seal lip.
• A tiny dab of suitable grease on the ball studs is fine to prevent squeaks—avoid the shaft.
• Replace in pairs so lift and balance stay even.

Swapping them is a straightforward diy job if you’re handy. Support the hatch with a prop or a mate, flick the spring clips off the socket ends, pop the old struts away, then press the new sockets onto the ball studs. Most struts fit rod‑end down to keep the internal seal wet—follow the supplier’s orientation. Don’t slam the hatch, and check it latches and opens smoothly a few times. If the XV wears a heavier accessory (bike rack on the hatch, added trim), talk to a specialist about the correct force rating, too “strong” can stress hinges and latches.

Expect a typical service life of 5–8 years depending on climate and use. If the hatch no longer holds itself up, it’s time.

FAQs

Does the 2012 Subaru XV have gas struts on the bonnet?
From factory, no—the bonnet uses a prop rod. The gas struts are on the rear tailgate. Aftermarket bonnet‑strut kits exist, but they’re not original equipment.

How long do the XV’s tailgate gas struts last?
Most last around 5–8 years in Aussie and NZ conditions. Cold weather, dust, and frequent use can shorten that. If the hatch won’t stay up or feels heavy, plan a replacement.

Can stronger gas struts be fitted for accessories on the hatch?
They can, but go carefully. Over‑spec struts can stress hinges, twist the panel, or make latching a pain. Match the force to the added weight and source quality parts designed for the GP‑series XV.
