Parts for your 2018 Mitsubishi Eclipse cross-Gas struts

2018 Mitsubishi Eclipse Cross gas struts

Gas struts are fitted to the tailgate of the 2018 Mitsubishi Eclipse Cross. Mitsubishi’s own technical literature identifies rear gate “stays” (gas springs) for Eclipse Cross GK-series models in the Body group of the Mitsubishi ASA electronic parts catalogue, and the 2018 Owner’s Manual rear gate section describes the lift-assisted hatch operation. The bonnet, by contrast, is shown with a support rod rather than gas struts in the same manual. Major OE suppliers also list tailgate gas springs for 2017–on Eclipse Cross models in their application guides.

On a 2018 Eclipse Cross, the tailgate gas struts do the heavy lifting, taking the strain out of opening the rear hatch and holding it safely at full height. They’re nitrogen-charged dampers designed to balance smooth motion with reliable holding force, even on a blustery day at the beach or a quick dash to the shops. As part of routine servicing, it’s worth checking how confidently the tailgate lifts and stays up. If it feels lazy, needs a shove to get going, or drops when it’s cold, the struts are likely past their best.

Replacement is a quick, tidy job, but it should always be done in pairs and with the door securely propped. Go for quality, correct-length struts matched to the factory Newton rating, mixing forces can twist the hinges and make the hatch sit wonky. A technician will support the tailgate, pop off the spring clips, swap the units, lightly grease the ball studs (never the chrome rod), and verify smooth, even travel. The rods should be kept clean and free of silicone sprays or petroleum grease, which can damage the seals. In typical Aussie and Kiwi conditions, expect 5–8 years of service life, shorter if the vehicle lives outdoors or does lots of short, frequent openings.

• Signs they’re due: tailgate sagging or dropping, slow rise in cold weather, visible oil mist on the rod, or a creak/hiss with reduced support.
• Safety tip: always prop the tailgate while changing struts—no one enjoys a surprise whack on the noggin.
• Best practice: replace both sides together and keep hands off the shiny rod—fingerprints attract grit that wears the seals.

Do the 2018 Eclipse Cross bonnet struts exist?

No. The 2018 Eclipse Cross bonnet uses a manual support rod rather than gas struts, as shown in the factory Owner’s Manual. If a hands-free lift is desired, aftermarket conversion kits exist, but fitment should be checked carefully against local regulations and warranty considerations.

How long do the tailgate gas struts usually last?

Most owners see 5–8 years, depending on climate, usage, and storage. Heat, dust, and constant short trips can shorten life. If one side weakens, replace both to keep the hatch aligned and the lift smooth.

Can gas struts be re-gassed, or should they be replaced?

While some specialists offer re-gassing, the safer, more reliable option is replacement with quality, vehicle-specific units. New struts restore the correct force and damping, and they’re generally cost-effective compared with rework.
