Parts for your 2014 Mitsubishi Outlander-Gas struts

2014 Mitsubishi Outlander gas struts — what they do and when to replace them

Per Mitsubishi Motors’ Factory Service Manual for the 2013–2015 Outlander (Body – Liftgate/Luggage Door section) and the Mitsubishi ASA/EPC parts listings for GF7W/GF8W models, the 2014 Outlander is fitted with a pair of gas-pressurised liftgate stays (gas struts) on the tailgate. The bonnet on this model uses a prop rod rather than gas struts.

On the Outlander, tailgate gas struts do the heavy lifting, counterbalancing the weight of the rear door so it opens smoothly and stays up without drama. They’re sealed units charged with nitrogen gas and a small amount of oil, providing consistent support and damping. When they’re healthy, the tailgate lifts with minimal effort and holds at full height, when they’re tired, it can sag, slam shut, or feel heavy — not ideal when loading the weekly shop or the pram.

As part of routine servicing, it’s smart to have the gas struts checked annually (or every 10,000–15,000 km). Cold weather will often expose a weak strut, so pay attention in winter. Typical signs they’re due are:

• Tailgate won’t stay up, sags, or closes on its own
• Slow or jerky opening, especially when cold
• Visible oil film on the rod, damaged end fittings, or a faint hiss/leak

Replacement is straightforward for a trained tech and should be done in pairs to keep lift and drop balanced. Always support the tailgate while swapping them over. Make sure the replacements match the correct length, end fittings, and force spec for the specific Outlander variant (rear spoiler, trim level, and accessories can change tailgate weight). Quality OEM or reputable aftermarket units are the go. Avoid “re-gassing” for these small automotive struts — they’re generally designed as non-serviceable and are best replaced.

Maintenance is mostly about not making life harder for the struts: don’t push down on the tailgate to close it, keep the polished rods clean and free of grit, and never paint or grease the rods (that ruins the seals). A light check of the ball studs and brackets for corrosion or looseness during servicing helps prevent premature wear. Dispose of old units safely, they’re pressurised, so don’t drill or heat them.

Popular questions

Does the 2014 Outlander have bonnet gas struts?
No — the bonnet uses a prop rod from factory. If bonnet lift assist is desired, there are aftermarket kits, but they should be installed with care to avoid stressing the bonnet or hinges.

How long do tailgate gas struts last on a 2014 Outlander?
Typically 4–8 years, depending on climate and use. Frequent opening, heat, and dust can shorten life. If the tailgate feels heavy, sags, or struggles in the cold, it’s time to replace both struts.

Can Outlander gas struts be re-gassed?
Not realistically. Most automotive lift supports are sealed-for-life items. Re-gassing isn’t reliable for these units, proper replacement with correctly rated new struts is the recommended fix.
