2016 Mitsubishi ASX Gas Struts — What They Do and When to Replace Them

Yes, gas struts are used on the 2016 Mitsubishi ASX. Technical references including the Mitsubishi Motors 2016 ASX Owner’s Manual (Body/Rear Hatch section), the Mitsubishi ASA/Global Parts Catalogue (ASX/RVR/Outlander Sport GA-series) listing “rear door stay” gas springs, and application guides from major OE suppliers (e.g., Stabilus Lift-O-MAT, Monroe Max-Lift) all confirm the ASX is factory-fitted with gas-charged lift supports on the tailgate. The bonnet is supported by a prop rod from factory, not gas struts.

On the ASX, the tailgate gas struts do the heavy lifting, literally. They hold the rear hatch up safely, make opening smooth, and stop it slamming down. Charged with nitrogen and a touch of oil for damping, they’re sealed units designed to deliver steady force through the opening arc. Over time, seals harden and pressure drops, especially with age, heavy use, or coastal conditions—then the hatch feels lazy, sags in the cold, or needs a helping hand to stay up.

There’s no fixed service interval, but most ASX owners will see 5–10 years from a set. It’s smart to check them during routine servicing:

• Signs they’re tired: hatch drops or won’t stay up, slow lift in winter, visible oil mist, rusty shafts, or creaking.
• Best practice: replace in pairs for even lift and latch alignment. Struts aren’t re-gassed—swap them out with the correct force-rated units for the GA-series ASX.

Replacement is straightforward and a good DIY for many, but do it safely. Support the tailgate with a prop or a mate—never trust a weak strut. Pop the metal retaining clips at the ball sockets with a small flat screwdriver, ease the old strut off, then click the new one on in the same orientation. Don’t twist the rod, don’t clamp the shaft with tools, and avoid grease or paint on the chrome shaft. A light silicone on the ball studs only is fine. After fitting, cycle the hatch a few times and check for smooth action and proper latching.

Keep the shafts clean, especially after beach trips, grit chews seals. Remember temperature affects performance—sluggish in cold is normal, but rapid drop or head bumps aren’t. For the bonnet, the 2016 ASX uses a prop rod, bonnet gas struts are aftermarket-only, so choose a reputable kit designed for the model to avoid fouling and undue hinge load.

• Safety tip: if a hatch starts to fall, replace the struts immediately—don’t risk fingers or a cracked rear glass.

Popular questions about 2016 Mitsubishi ASX gas struts

Do 2016 ASX models have gas struts on the bonnet?
From factory, no—the bonnet uses a prop rod. Only the tailgate has gas-charged struts. Aftermarket bonnet kits are available for the GA-series ASX, choose a model-specific kit and check clearance with the bonnet and guards.

How long do tailgate gas struts last on a 2016 ASX?
Typically 5–10 years, depending on climate and usage. If the hatch won’t stay up, drops in cold weather, or you see oil mist on the shaft, it’s time to replace them—ideally as a pair for balanced lift.

Can ASX gas struts be re-gassed or adjusted?
They’re sealed units and not serviceable. The fix is replacement with the correct force-rated struts for the ASX. Avoid universal struts unless their length, fittings, and rating exactly match the OE spec.
