Parts for your 2006 Subaru Forester-Gas struts

2006 Subaru Forester Gas Struts

Based on technical references, gas-charged struts are indeed fitted to the 2006 Subaru Forester’s rear gate. The Subaru Factory Service Manual for MY2006 Forester (Body – Rear Gate) specifies gas-charged “stays” supporting the tailgate, and the Subaru FAST parts catalogue lists “Stay – Rear Gate” (LH/RH) for the SG-series Forester. From factory, the bonnet on this model uses a manual prop rod, any bonnet gas struts are aftermarket additions, not OEM.

On a 2006 Subaru Forester, gas struts on the tailgate do the heavy lifting: they counterbalance the rear gate so it opens smoothly and stays safely overhead. Charged with nitrogen and a dab of oil for damping, they make the tailgate feel light, prevent slamming, and keep things stable in windy conditions. When they’re healthy, the rear gate lifts predictably and holds its height without fuss.

Like any sealed strut, they lose pressure over time. Age, temperature swings, contamination on the chrome shaft, and plenty of open/close cycles all chip away at their performance. Common signs it’s time to replace include:

• Tailgate drops or won’t hold itself up (especially in cold weather).
• Slow, uneven, or jerky opening and closing.
• Needing to “help” it up by hand.
• Oily film, rust, or nicks on the strut shaft.
• Clicking at the ball sockets or loose brackets.

Best practice is to replace tailgate gas struts in pairs so opening force stays balanced side-to-side. It’s a straightforward job: support the gate securely with a prop or helper, pop off the retaining clips, swap each strut, then confirm smooth, hands-off operation through the full travel. Avoid gripping the polished shaft with tools or adding grease—just keep it clean and free of silicone sprays and paint overspray. Inspect the ball studs and brackets for corrosion or play and tighten hardware to spec during servicing.

Selecting replacements? Match the SG Forester’s fitment by length (extended and compressed), end style (ball socket), and force rating. Quality aftermarket or genuine units are both fine if they meet the correct specs. Disposal matters too—gas struts are pressurised, so don’t crush or burn them, recycle as advised.

As part of routine servicing, a quick wipe of the shafts, a check for leaks, and a seasonal test in cooler weather will keep the Forester’s tailgate behaving as it should. If the bonnet needs hands-free lift, note that bonnet gas strut kits are aftermarket, as the OEM setup is a simple prop rod.

Popular questions about 2006 Subaru Forester gas struts

Are gas struts standard on the 2006 Forester?
Yes—on the rear tailgate. The SG-series (MY2006) Forester uses a pair of gas-charged stays to support the rear gate from factory. The bonnet, however, ships with a prop rod. Bonnet gas strut kits are an optional aftermarket upgrade if hands-free bonnet lift is desired.

How long do the tailgate gas struts typically last?
Usually 5–10 years, depending on climate and usage. Cold mornings can make tired struts feel noticeably weaker, and coastal environments can speed up corrosion. If the gate won’t hold itself up or opens sluggishly, it’s time for a new pair.

Can they be replaced at home?
Absolutely. With the tailgate safely propped, each strut can be swapped in minutes by releasing the metal clips and snapping the new units onto the ball studs. Replace both sides together for balanced lift, and avoid touching or lubricating the chrome shafts.
