Parts for your 2010 Subaru Impreza-Gas struts

2010 Subaru Impreza gas struts — what they do and when to replace

For the 2010 Subaru Impreza, gas struts are relevant and factory-fitted to the hatchback’s tailgate (GH/GR). The sedan’s boot uses torsion rods rather than gas struts, and the bonnet is supported by a prop rod, not gas struts. This layout is confirmed across Subaru service literature for the GE/GH/GR/GV generation (Body/Rear Gate sections), Subaru parts catalogues (EPC/FAST listings for lift supports on hatch variants), and common application guides from gas-spring manufacturers such as Stabilus (LIFT-O-MAT) and Monroe/StrongArm for 2008–2011 Impreza hatchbacks.

On the hatch, the gas struts counterbalance the weight of the tailgate so it lifts smoothly, stays up securely, and closes without a thud. They’re sealed, nitrogen-charged dampers designed to work in a wide temperature range, providing controlled motion and reducing stress on hinges and the body shell. When healthy, they’ll hold the gate open without hesitation, even on a windy day.

Like any gas spring, they lose charge over time. Telltales include the tailgate drifting down, a chattering or stick–slip feel near the top, oily misting around the shaft seal, and worse performance in cold weather. If anyone has to “shoulder” the hatch to keep it up, the struts are due.

Replacement is straightforward with the right approach. Support the tailgate with a prop before starting. Swap struts one at a time and, ideally, in pairs so lift and damping stay balanced. Use a small flat-blade to pop the metal retaining clips on the ball sockets—no need to fully remove the clip. Avoid locking pliers on the chrome shaft
