Subaru Legacy Liftgate Lift Supports

Subaru Legacy Liftgate lift supports

Starting at $17.95, AutoBuffy stocks 10 liftgate lift supports from Tuff Support and Monroe. A liftgate lift support is a gas-charged strut that holds your Subaru Legacy's rear hatch or tailgate open hands-free. When it fails, the liftgate falls unexpectedly under its own weight, creating a safety hazard and making cargo loading a two-person job.

Signs your Subaru Legacy needs new liftgate lift supports

  • Liftgate falls down slowly or drops immediately after being raised
  • You have to prop the liftgate open with a stick or your arm to keep it up
  • Liftgate only stays up partway instead of rising to its full open position
  • Visible oil residue or wet streaking on the strut body, indicating a failed gas seal
  • Liftgate feels unusually heavy or requires excessive force to lift manually
  • Strut body is visibly bent, corroded, or the end mounting ball socket is cracked or loose

Which liftgate lift support should you buy for your Subaru Legacy?

The most important factors are correct extended and compressed length, gas pressure rating (measured in pounds of force), and end fitting style — all must match the original specs for your Subaru Legacy. Aftermarket options range from economy replacements to OE-equivalent units; on rear hatches with dual supports, both struts should always be replaced as a pair so lift force stays balanced.

Subaru Legacys under warranty or with strict fit requirements
What you get
Exact factory spec, guaranteed fitment; typically highest cost option
Sold as Pair
Best for
Any Subaru Legacy with two supports (most hatchbacks and SUVs)

Replacing liftgate lift supports on a Subaru Legacy

Easy⏱ 15–30 minutesFlat-head screwdriver or trim pry tool (for clip-style end fittings)Safety prop or second person to hold liftgate openSafety glassesNeedle-nose pliers (if retaining clips are present)

Prop the liftgate securely open, then use a pry tool or your thumb to pop each strut end off its ball stud — start at the bottom mount and work upward. Snap the new struts onto the ball studs in reverse order, bottom first, until each end clicks firmly into place. No special tools or torque specs are required; the press-fit ball socket is the only fastener on most Subaru Legacy applications.

Frequently asked questions

How much does it cost to replace liftgate lift supports on a Subaru Legacy?
Parts for a Subaru Legacy start at $17.95 per strut at AutoBuffy. Most vehicles use two supports, so budget for a pair. Professional labor is typically under an hour and adds modest shop fees. Replacing them yourself is straightforward and cuts the total cost significantly.
Can I drive my Subaru Legacy with a broken liftgate lift support?
Yes, a failed lift support does not affect driveability. However, a liftgate that drops unexpectedly can cause head or hand injuries during loading and unloading. It can also stress hinge hardware over time. Replacement is low cost and low effort, so there is little reason to leave it unrepaired.
Do I need to replace both liftgate lift supports at the same time on my Subaru Legacy?
Yes. Lift supports wear at roughly the same rate because they share the same load cycles. Replacing only one leaves mismatched gas pressure, causing the liftgate to open unevenly and placing extra stress on hinges and the stronger strut. Replacing both at once also saves labor time on your Subaru Legacy.
How long do liftgate lift supports last on a Subaru Legacy?
Service life varies with climate, use frequency, and part quality, but most lift supports last somewhere between 50,000 and 100,000 miles or roughly five to ten years. Exposure to extreme cold, road salt, and frequent liftgate cycling shortens that range noticeably on a Subaru Legacy used in harsh conditions.
Are aftermarket liftgate lift supports as good as OEM on a Subaru Legacy?
Premium aftermarket lift supports from established brands like Tuff Support and Monroe are engineered to match OE gas pressure, end fitting dimensions, and travel length. For most Subaru Legacy owners they perform on par with dealer parts at a lower price. Economy-grade units may have a shorter service life but still restore safe liftgate function.
How do I know which liftgate lift support fits my Subaru Legacy?
The critical specs are extended length, compressed length, gas force rating in pounds, and end fitting type — typically a ball socket or pin. Use AutoBuffy's year-make-model lookup to filter 10 available options down to confirmed fits for your Subaru Legacy. Never rely on visual similarity alone, as dimensions vary across trim levels.
