Parts for your 2006 Mitsubishi Lancer-Gas struts

2006 Mitsubishi Lancer gas struts — what’s fitted, what’s not, and how to look after them

Based on technical sources — Mitsubishi Lancer (CH/CS, 2002–2007) Service Manual body sections, the Mitsubishi ASA/EPC parts catalogue, and aftermarket application guides from Stabilus Lift-O-MAT and Monroe Max-Lift — gas struts are not used on the 2006 Lancer sedan’s bonnet or boot. The sedan bonnet is supported by a prop rod, and the boot uses torsion-bar hinges. However, the 2006 Lancer Wagon (CS5W) does use a pair of gas struts to support the rear tailgate.

Why the difference? Sedans commonly use torsion bars for compact packaging and cost, and a prop rod under the bonnet is simple and reliable. The wagon’s large, heavy liftgate needs gas-charged struts (stays) to lift smoothly and hold safely overhead.

For 2006 Lancer Wagon owners, those tailgate gas struts do the heavy lifting. They’re filled with nitrogen and a light oil, providing controlled assistance so the hatch opens easily and stays put, even in a breeze. Over time, seals age, gas pressure drops, and the struts lose oomph — the gate starts sagging, opens slowly, or won’t stay up. That’s the cue to replace them.

• Typical signs they’re tired: needing a shoulder to finish lifting, tailgate creeping down, or a thud when closing instead of a damped motion. Colder weather often makes weak struts feel worse.
• Service tip: keep the chrome shafts clean and dry. Don’t spray silicone, oil, or grease on the shafts — it can damage seals and attract grit.
• Safety first: always support the tailgate with a prop or a helper before removing any strut. These are under pressure.

Replacement is straightforward with basic tools. Most units are held by spring clips at each end: flick the clip back with a small screwdriver, pop the joint off, and swap the strut. It’s best to replace in pairs to keep lift and damping even. Match the new struts by body style (wagon), model year, and mounting style, reputable aftermarket catalogues list correct lengths, end fittings, and force ratings for the CS5W tailgate. If the old ball studs are worn, replace those too.

How long do they last? There’s no fixed interval — many go 5–10 years, but heat, use, and dust can shorten that. As part of regular servicing, a quick check of tailgate hold and lift effort helps catch weak struts before they become a hazard. For sedan owners: no gas struts to service on the boot or bonnet unless an aftermarket kit has been fitted.

• Which 2006 Lancer models actually have gas struts?

The 2006 Lancer Wagon (CS5W) uses gas struts on the tailgate. The 2006 Lancer sedan uses a prop rod for the bonnet and torsion bars for the boot, so no factory gas struts there. Any bonnet/boot gas struts on a sedan are likely aftermarket kits.

• How often should tailgate gas struts be replaced on a 2006 Lancer?

There’s no set schedule. Replace them when the tailgate won’t stay up, opens sluggishly, or feels heavier than usual — symptoms that often show sooner in cold weather. Many struts last 5–10 years, but usage and climate make a big difference.

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

On this model, replacement is the usual fix. Most automotive lift struts are sealed units not intended for re-gassing. New, correctly rated struts are inexpensive, quick to fit, and more reliable than attempting a recharge.
