Parts for your 2012 Mitsubishi Outlander-Gas struts

2012 Mitsubishi Outlander gas struts

Gas struts are indeed used on the 2012 Mitsubishi Outlander. Technical sources identify two gas-filled lift supports fitted to the upper tailgate/hatch on the CW-series Outlander (2007–2012). The Mitsubishi workshop manual (Group 42A – Body, Liftgate/Back Door) refers to these as “back door lifters,” and the Mitsubishi ASA electronic parts catalogue lists a gas spring for the rear gate on 2012 models. Major aftermarket application guides (e.g., Stabilus Lift-O-Mat and Monroe Max-Lift) also specify a matched pair of rear lift supports for the 2007–2012 Outlander. The bonnet on most trims uses a prop rod, not gas struts.

On this Outlander’s split-tailgate design, the gas struts handle the upper hatch. Their job is to counterbalance weight, lift smoothly, and hold the hatch open so loading’s easy and safe. When healthy, they raise cleanly and don’t sag, even on a breezy day or a chilly morning.

There’s no set service interval, but by the 8–12 year mark many originals are tired—especially if the vehicle lives outdoors or sees a lot of hatch cycles. Replacement is the fix, gas struts are sealed units and aren’t serviceable. Best practice is to replace them in pairs so the hatch opens evenly and the latching and hinges aren’t put under uneven load.

• Common signs they’re due: the hatch won’t stay up, drops suddenly, opens sluggishly (worse in cold weather), needs a shove to start moving, or shows an oily film around the rod seals.
• Owner-friendly care: keep the chromed rods clean and free of grit, don’t lubricate them with grease or silicone—just wipe with a soft, dry cloth. Avoid using the struts as handholds.
• Fitment tips: support the hatch with a prop or helper, then swap one strut at a time. Release the spring clip at each ball joint, click the new unit on, and ensure the clip is fully seated. Observe orientation arrows where supplied. Refer to the workshop manual for bracket bolt torque on the back door lifter mounts.
• Safety: treat old units as pressurised cylinders, don’t heat, crush, or puncture them. Recycle appropriately.

Choosing quality replacements with the correct Newton rating for the 2012 Outlander will restore smooth, controlled lift and proper hold-open force. That keeps the cargo area safer to use and protects hinges and latches from extra strain.

Do the 2012 Outlander’s bonnet use gas struts?

Most 2012 Outlander variants use a manual prop rod for the bonnet, not gas struts. Aftermarket bonnet strut kits exist, but they’re add-ons and should be chosen to suit the specific model and mounting points.

Is it okay to replace just one rear gas strut?

It’s strongly recommended to replace both. A single new strut paired with a weak old one can twist the hatch, strain hinges, and reduce hold-open safety. A matched pair restores balanced lift and proper damping.

What’s the typical lifespan of Outlander tailgate struts?

Many sets last 5–10 years, depending on climate and usage. Cold temperatures, coastal environments, and frequent opening/closing can shorten life. If the hatch hesitates, sags, or needs a shove, replacement time has likely arrived.
