Parts for your 2017 Mitsubishi Asx-Gas struts

2017 Mitsubishi ASX Gas Struts — Fitment, Purpose, and Service Advice

Technical sources confirm gas struts are used on the 2017 Mitsubishi ASX. The Mitsubishi Motors service/workshop information for ASX/RVR (2016–2019) Body section identifies gas-filled lift supports on the rear tailgate, while the bonnet is held up by a manual prop rod. This is echoed in the Mitsubishi ASA electronic parts catalogue (Body/Rear Gate: Gas Spring) and common aftermarket catalogues (e.g., Stabilus/Monroe) listing tailgate lift supports for the 2017 ASX. So, gas struts are relevant to the vehicle’s tailgate, the bonnet is not factory-fitted with gas struts.

On a 2017 ASX, the tailgate gas struts quietly do the heavy lifting. Charged with nitrogen and a dash of oil, they counterbalance the tailgate’s weight so it pops up smoothly and stays put overhead. They also control the descent, so the hatch doesn’t come crashing down on a windy day or when it’s cold in a Kiwi winter or an Aussie southerly. While the bonnet uses a prop rod from factory, many owners fit aftermarket bonnet struts for convenience, the OE struts, however, live at the tailgate.

As part of routine servicing, it’s worth giving the tailgate struts a quick once-over. Look for a light oil film weeping from the rod seal, sluggish or uneven lifting, creaks, or a hatch that won’t stay up—especially noticeable in cold weather. If one side looks tired, plan to replace both, matched pairs keep the tailgate balanced and reduce hinge stress. Replacement is typically straightforward: support the hatch safely, flick off the retaining clips at the ball ends, swap the strut, and click the new one home. Never clamp or scratch the chrome rod, and don’t grease it—just wipe it clean with a soft cloth. Orientation matters too: fit them in the same rod-up/rod-down position as the originals to keep the internal seal bathed in oil.

Service tips for ASX owners and workshops:

• Inspect operation every 10,000–15,000 km service or annually.
• Replace in pairs when lift slows, the hatch drops, or there’s visible leakage.
• Choose struts matched to VIN/trim, spoilers or accessories can change the required force rating.
• Support the tailgate during work—use a prop or a second person for safety.

Look after the struts and they’ll usually last 5–8 years. When they’re tired, fresh units instantly restore that new-car “lift and hold” feel that makes daily use of the ASX’s boot a breeze.

Popular questions about 2017 Mitsubishi ASX gas struts

Do all 2017 ASX models have gas struts on the bonnet?
From factory, the bonnet uses a manual prop rod, not gas struts. Only the rear tailgate is equipped with gas-filled lift supports. Aftermarket bonnet strut kits are available if extra convenience is wanted, but they aren’t OE fitment.

How do I know when the tailgate struts need replacing?
Common signs include the hatch not staying up, slow or jerky lifting, needing to be helped by hand, or an oily film on the strut rod. Cold mornings often expose weak struts. If any of these show up, replace both sides together.

Can I change the ASX tailgate struts at home?
Yes, it’s a straightforward DIY for many owners. Support the tailgate securely, pop the retaining clips, and swap like-for-like parts. Avoid touching the chrome rod with tools, and install with the same orientation as the originals.
