Parts for your 2023 Subaru Outback-Gas struts

2023 Subaru Outback gas struts

Technical sources confirm gas struts are used on the 2023 Subaru Outback. The 2023 Subaru Outback Owner’s Manual describes a Power Rear Gate that relies on gas‑charged lift supports, and the Subaru OEM parts catalogue lists “liftgate stays/gas springs” for this model. The bonnet is supported by a prop rod rather than gas struts, but the rear liftgate definitely uses them (including on power liftgate variants, where the struts work alongside the electric actuator).

On a 2023 Outback, gas struts do the heavy lifting for the tailgate. They’re nitrogen‑charged dampers that counterbalance the weight of the gate, so it opens smoothly and stays put overhead without dropping on a windy day. Even on models with a powered rear gate, the motor is assisted by these struts to control speed, reduce load and keep things quiet and predictable.

Owners will notice the struts doing their best work when the vehicle is parked nose‑up on a driveway or on cold mornings—both situations that test a weak strut. If the tailgate creeps down, feels heavy, or needs a shove to get moving, the struts are likely past their best.

As part of regular servicing for a 2023 Subaru Outback, a quick strut check is a smart move:

• Inspect for oil film, dents, rust on the shaft, or cracked end fittings.
• Open the tailgate fully and confirm it holds position without sagging.
• Listen for squeaks or binding at the ball studs and brackets.

Care is simple: keep the chrome shafts clean, wipe with a soft cloth only. Avoid paint, solvents, or grease on the shafts—lubricants attract grit and damage the seals. A dab of silicone-safe spray on the ball joints (not the shaft) can reduce squeaks. Don’t use the tailgate as a handle to pull the vehicle closed by the strut body.

Replacement is straightforward and best done in pairs so lift and balance stay even. Because the Outback’s gate is heavy, support it with a prop and have a second person on hand. Pop the retaining clips, swap the old struts for new OE‑spec units, and ensure each clip seats fully on the ball studs. After refitting, cycle the gate a few times so the power system (if fitted) relearns the stroke and latch positions. Fresh struts restore smooth operation and protect the power actuator, trim, and hinges from strain—well worth the quick service attention.

Popular questions about 2023 Subaru Outback gas struts

How long do the Outback’s tailgate gas struts usually last?

Most owners see 5–8 years depending on climate and use. Heat, dust, and frequent heavy tailgate cycles can shorten lifespan. If the gate feels heavy, drops unexpectedly, or won’t reach full height in cooler weather, it’s time to plan a replacement.

Can someone replace just one gas strut on the Outback?

It’s possible, but not recommended. Replacing in pairs keeps lift and damping even, reduces twist on the hinges, and helps the power actuator (if fitted) work within spec. Mixing an old, tired strut with a new one often leads to uneven operation and early wear.

Do power liftgate models use different struts?

Yes. Power tailgate Outbacks pair the actuator with matched gas struts calibrated for the system. Use the correct OE‑spec part numbers for power or manual configurations to maintain proper lift speed, hold height, and safety performance.
