Parts for your 2011 Mitsubishi Outlander-Gas struts

2011 Mitsubishi Outlander gas struts — what they do and when to replace them

Gas struts are very much used on the 2011 Mitsubishi Outlander. The Mitsubishi Workshop Manual (Body – Liftgate section) specifies two gas springs supporting the upper rear hatch on CW-series Outlander models, and Mitsubishi’s ASA parts catalogue lists “gas spring, back door” for the 2011 range. Major aftermarket catalogues for Stabilus/Lift-O-Mat and Monroe also list rear liftgate struts for 2007–2012 Outlander, confirming fitment. The bonnet on this model is factory-supported by a prop rod, not gas struts.

On this Outlander, the gas struts sit either side of the upper tailgate and do the heavy lifting. They’re nitrogen-charged dampers that make the hatch easy to lift, hold it open safely, and lower it smoothly without a slam. Good struts protect hinges and latches from shock loads and save shoulders and backs from doing the work.

As part of routine servicing, it pays to give the gas struts a quick once-over. Wipe the chrome shafts clean, check the end fittings for play, and listen for creaks. Temperature swings, salt air, and constant use can all shorten their life, so coastal and high-kilometre vehicles often need replacements sooner.

• Tell-tale signs it’s time: the hatch sags or won’t stay up, lifts unevenly, needs two hands, drops faster in cold weather, or shows oily residue on the strut body.

When replacement is due, always change them in pairs to keep the hatch balanced. Support the tailgate with a prop and a helper, then pop off the spring clips at the ball sockets and swap the struts. Don’t twist the shaft, don’t clamp or lubricate the chrome rod, and avoid getting silicone or grease on it—contamination damages the seals. Lightly lube the ball joints only, then torque any bracket fasteners to spec. Choose OE or quality aftermarket units matched to the VIN so the opening force and stroke are correct for the split-tailgate design.

Owners often ask about bonnet struts. From factory, the 2011 Outlander bonnet uses a prop rod, bonnet gas-strut kits are aftermarket-only. If fitting a kit, ensure brackets don’t foul wiring or the guard and that open height still clears the garage door.

FAQs

How long do the Outlander’s tailgate gas struts usually last?
Most see 5–8 years, but climate and use matter. Cold mornings reveal weak struts first because internal gas pressure drops with temperature. If the hatch won’t hold up in winter, plan a replacement.

Can they be replaced at home?
Yes, with a helper, a prop, and a small flat screwdriver for the retaining clips. Swap one side at a time, keep fingers clear of the hinges, and avoid bending the new strut shafts. It’s a quick job if the parts are correct for the vehicle’s VIN.

Why does the tailgate drop faster in cold weather?
Gas pressure falls as temperature drops, so a tired strut loses support in the cold. If it’s marginal in winter, it’s already due—fresh struts will hold properly year-round.
