Parts for your 2019 Mitsubishi Asx-Gas struts

2019 Mitsubishi ASX gas struts — what they do and when to replace them

Yes, gas struts are relevant to the 2019 Mitsubishi ASX. Technical documentation from Mitsubishi’s workshop manual for ASX/RVR (Body – Liftgate/Rear Gate section) and the Mitsubishi ASA electronic parts catalogue identify two gas‑charged lift supports on the rear tailgate. The bonnet on this model uses a manual prop rod, not gas struts. Application catalogues from major OE suppliers (e.g., Stabilus/Monroe/StrongArm) also list rear liftgate gas springs specifically for 2019 ASX/RVR/Outlander Sport models, confirming fitment.

On the 2019 ASX, the gas struts are there to make life easy every time the tailgate’s opened. They counterbalance the weight of the hatch so it lifts smoothly and stays put without a fight. When they’re healthy, there’s a light, controlled rise and a steady hold at full height, when they’re tired, the tailgate feels heavy, lifts slowly (especially in cold weather), or won’t stay up.

There’s no fixed replacement interval for gas struts, they’re a wear item that usually last several years, often 5–10 depending on climate and usage. As part of regular servicing, it’s smart to give them a quick check:

• Open the tailgate and see if it rises confidently and holds at full height.
• Look for oil misting or wetness on the strut shaft or body.
• Listen for creaks or notice any binding/jerky movement.

If any of that shows up, replacement is the go. Best practice is to replace them in pairs so lift and hold are balanced. It’s generally a straightforward DIY job: support the tailgate safely (a helper or prop is essential), pop off the retaining clips at each end, swap the strut, then click the clips back on. Avoid grabbing or greasing the polished shaft—keep it clean and dry so the seals last.

Workshops will also check the ball studs and brackets for wear or looseness and apply the correct torque when needed. If the struts are consistently slow in winter but OK in summer, that’s a sign they’re on the way out. For vehicles with accessories like a tailgate spoiler or added rear‑gate weight, choose heavy‑duty rated replacements to restore proper lift.

Bottom line: the 2019 ASX definitely uses gas struts on the tailgate, they’re crucial for safe, easy operation, and they’re quick to sort when they start to fade.

• Do 2019 Mitsubishi ASX models have gas struts on the bonnet?
  No—the bonnet uses a manual prop rod. Gas struts are fitted to the rear tailgate only on this model. That’s as shown in Mitsubishi’s service manual and parts catalogue for the ASX/RVR platform.
• How long do ASX tailgate gas struts usually last?
  Typically 5–10 years, depending on climate, usage, and added tailgate weight. Cold weather often exposes weak struts sooner—if the hatch won’t stay up on a chilly morning, it’s time.
• Can ASX gas struts be re‑gassed, or should they be replaced?
  Most OE‑style struts are sealed units. While some local services offer re‑gassing, replacement with quality struts is usually quicker, cost‑effective, and more reliable for the long term.
