Parts for your 2024 Mitsubishi Asx-Gas struts

2024 Mitsubishi ASX gas struts — what they do and when to replace them

Based on technical sources, gas struts are fitted to the 2024 Mitsubishi ASX for the rear tailgate. The bonnet uses a prop rod rather than gas struts. This is confirmed by the 2024 ASX Owner’s Manual (AU/NZ) notes on the back door supports and cautions, and by listings in Mitsubishi’s Electronic Parts Catalogue (EPC/ASA) under Body – Back Door – Stay/Gas Spring for the ASX (XB/XC series). So yes, gas struts are relevant on this model.

On the ASX, the tailgate gas struts are the tidy, gas-charged springs that take the weight of the rear hatch, slow the movement so it doesn’t slam, and hold it open at a safe height. They make daily use easier, especially when loading the boot with the weekly shop or beach gear. Because they’re sealed, they don’t need regular adjustment, but they do wear gradually as the internal gas pressure drops.

As part of routine servicing, it’s smart to give them a quick check. A tech will look for light oil misting on the rod, any bends, chipped chrome, or cracked end fittings, and they’ll confirm the hatch stays up by itself. In cold weather, weak struts show up faster.

• Common signs it’s time to replace: the tailgate sags or drops, opens sluggishly, needs a push past halfway, or you see oily residue on the shaft.
• Care tips: keep the chromed rods clean and dry, don’t grease the rods (it attracts grit and chews the seals), and avoid using the hatch as a leaning post in strong wind.
• Replacement advice: always replace in pairs, match the OEM Newton rating and end fittings, and support the hatch with a prop or a helper during the swap. If accessories have added weight to the hatch, discuss spec with a technician.

Most owners will see many years from a set, but usage, heat, and dust all chip away at performance. During scheduled services (for example every 20,000 km), asking for a quick lift-and-hold test is a simple way to stay ahead of any surprise tailgate drop. Genuine or quality aftermarket units both do the job, provided the force rating and length are correct for the 2024 ASX.

Does the 2024 Mitsubishi ASX have gas struts on the bonnet too?

No. The 2024 ASX uses a prop rod for the bonnet and gas struts for the rear tailgate only. That’s typical for this class of vehicle and helps keep weight and cost down while keeping the tailgate effortless to use.

How long do ASX tailgate gas struts usually last?

There’s no fixed interval, but many last 5–10 years depending on climate and use. Lots of heat, dust, or frequent cycling can shorten their life. If the hatch no longer holds itself up or feels heavy, it’s time to replace the pair.

Can just one tailgate strut be replaced on a 2024 ASX?

It’s best practice to replace them in pairs. Mixing an old weak strut with a new strong one can twist the hatch, stress the hinges, and lead to uneven closing or early failure.
