Parts for your 2014 Mitsubishi Asx-Gas struts

2014 Mitsubishi ASX gas struts: fitment, purpose, and service tips

Gas struts are absolutely relevant to the 2014 Mitsubishi ASX. Technical sources including the Mitsubishi Motors ASX/Outlander Sport (GA-series) service manual (Body section – Liftgate/Hatch), Mitsubishi ASA/CAPS parts catalogues, and major application guides from gas-strut manufacturers (e.g., Stabilus Lift-O-Mat and Monroe Max-Lift) all list and illustrate two gas-charged support struts fitted to the rear tailgate of the 2010–2016 ASX range. Those same sources show the bonnet uses a manual prop rod from factory, not gas struts.

On the ASX, the tailgate gas struts do the heavy lifting—literally. They counterbalance the weight of the rear door so it opens smoothly, stays up securely, and closes with controlled motion. Beyond convenience, they’re a safety item: healthy struts stop the tailgate from dropping onto someone’s head or shoulders. Correct strut force, length, and end fittings are critical to keep alignment right and hinges happy.

Being sealed, nitrogen-charged dampers, gas struts will gradually lose pressure. By the age of a 2014 model, many originals are tired—especially if the car lives outdoors or sees big temperature swings. During servicing, a quick check is smart: lift effort, hold-at-top, and smooth damping. Any oily film on the shaft, slow or uneven extension, or the need to “help” the tailgate stay up are clear signs it’s time.

• Replace in pairs to keep even lift and hinge load.
• Match OE-spec length, force rating, and ball/socket ends.
• Fit rod-end down (shaft low) to keep internal seals lubricated.
• Never lubricate the chrome shaft, keep it clean and nick-free.
• Support the tailgate when swapping struts—use a prop or helper.

Installation is straightforward: carefully pop the retaining clips, swap the unit, and ensure clips are fully seated. Do not drill, heat, or attempt to vent a strut—they’re high-pressure. If hardware is removed, tighten to the specs in the Mitsubishi service manual and check alignment. While bonnet gas struts weren’t factory-fitted, aftermarket bonnet strut kits exist, if choosing to retrofit, use engineered brackets designed for the ASX and check that the change doesn’t affect warranty or panel alignment.

How long do ASX tailgate gas struts last?

Typically 5–10 years depending on climate and usage. If the tailgate won’t stay up, opens sluggishly, or needs a shove to start moving, they’re due. Age alone on a 2014 vehicle often justifies proactive replacement.

Can the original struts be re-gassed?

Most OE-style units are sealed and designed for replacement rather than re-gassing. Some local specialists can re-gas, but results vary, using new struts to the correct force specification is the reliable fix.

Does the 2014 ASX have bonnet gas struts from factory?

No—factory fitment is a manual prop rod per Mitsubishi service documentation. Aftermarket bonnet strut kits are available, choose ASX-specific hardware and verify clearances and mounting integrity.
