Parts for your 2006 Nissan Primera-Gas struts

2006 Nissan Primera gas struts — what they do and when to swap them

Based on the Nissan Electronic Parts Catalog (P12 series), the Nissan workshop manual, and major aftermarket catalogues (Stabilus Lift-O-Mat and Monroe Max-Lift), the 2006 Nissan Primera hatch and wagon are fitted with gas struts on the rear liftgate, while the sedan typically uses torsion bars for the boot lid and the bonnet uses a prop rod rather than gas struts. So, gas struts are absolutely relevant on hatch and wagon models for holding the tailgate safely open.

On a 2006 Primera hatch or wagon, gas struts (also called lift supports or gas springs) counterbalance the weight of the tailgate, making it easy to open and preventing it from crashing down. Inside each strut is pressurised nitrogen and a bit of oil, providing smooth, damped movement. Over time, seals wear and the gas charge drops, so the tailgate starts to sag, needs a shove to open, or falls shut in cold weather — all classic signs the struts are due.

For servicing, it’s smart to check the gas struts annually. If the tailgate won’t stay up or feels heavy, replace both sides as a pair to keep load even and hinges happy. Swapping them is a straightforward DIY for most owners: support the tailgate with a prop or a mate, flick off the retaining clips at each end, pop the old struts off the ball studs, press the new ones on until they click, then refit the clips. Use the correct specification for your body style, quality units will list the Primera P12 fitment and the required force rating. If in doubt on torque or clip style, refer to the P12 service manual.

• Care tips: keep the chrome rods clean, don’t grease them with petroleum products — a light silicone wipe is fine.
• Avoid slamming the tailgate, check hinge alignment and latch striker so the struts aren’t fighting misalignment.
• Expect lifespan of roughly 5–10 years depending on climate (cold and coastal conditions can shorten it).

If you’ve got the P12 sedan, the boot uses torsion bars rather than gas struts, which is why you won’t find lift supports listed for that lid. And regardless of body style, the bonnet is held up by a prop rod from factory, not struts.

Popular questions about 2006 Nissan Primera gas struts

Do all 2006 Primeras have gas struts?
Hatch and wagon models have gas struts on the tailgate. The sedan generally uses torsion bars for the boot, and the bonnet on all body styles uses a prop rod, not struts.

How long do Primera gas struts last?
Typically 5–10 years. Cold winters, heat, and grit can shorten their life. If the tailgate sags or won’t stay up, it’s time.

Can I replace just one strut?
Best practice is to replace both together. Mismatched force can twist the tailgate and wear hinges.
