Parts for your 2014 Nissan Dualis-Gas struts

2014 Nissan Dualis gas struts: fitment, purpose and easy service advice

Gas struts are fitted to the 2014 Nissan Dualis (J10) on the rear tailgate/back door. This is confirmed by Nissan’s J10 service manual (Body section: Back Door – which specifies gas‑charged back door stays), the Nissan Electronic Parts Catalogue (FAST) which lists back door gas stays for J10 models around 2013–2014 (commonly referenced under 90450‑JD00A/JD00B, depending on variant), and major aftermarket catalogues from Monroe Max‑Lift and Stabilus Lift‑O‑Mat that specify liftgate gas struts for 2007–2014 Dualis and Dualis+2. The bonnet on Australian/New Zealand‑market Dualis models uses a prop rod from factory, not gas struts.

On the 2014 Dualis, the tailgate gas struts do the heavy lifting—literally. They counterbalance the hatch so it opens smoothly and stays put overhead without dropping on shoulders. When they’re healthy, the tailgate lifts with a light push and holds firm, even on a breezy day. When they’re tired, the hatch feels heavy, lifts slowly (especially in cold weather), or sags back down—classic signs the nitrogen charge has faded or seals are worn.

As part of regular servicing, it’s smart to give the gas struts a once‑over. Look for oily residue on the rod, listen for creaks, and check for rust at the end fittings. Wipe the exposed rod with a clean, dry cloth—no grease or silicone sprays, as those can damage the seals. If the hatch no longer holds itself up, plan a replacement.

Replacement is a straightforward DIY or workshop job, usually taking 10–20 minutes. Always support the tailgate safely with a prop or helper—one strut off won’t hold the door. Replace in pairs so the lift is balanced and the new strut isn’t overworked. Most units clip on and off with a small locking spring, reuse or replace the clips as supplied, and ensure the sockets snap fully onto the ball studs. After fitting, cycle the tailgate a few times to confirm smooth operation and solid hold at full height.

For Dualis+2 (the seven‑seater), struts are tuned to the different tailgate weight, so match parts to the exact variant. Workshop teams will also check the hinge alignment and tailgate weight (added accessories like a heavy spoiler or glass changes matter), because extra mass can shorten strut life.

With fresh gas struts, the Dualis tailgate feels light, predictable, and safe—no more shoulder juggling or surprise drops at the shops.

Popular questions about 2014 Nissan Dualis gas struts

Do all 2014 Dualis models have bonnet gas struts?
From factory, the Dualis uses a prop rod for the bonnet, not gas struts. Aftermarket bonnet‑strut kits exist, but they’re not OEM. The fitted gas struts are on the rear tailgate/back door.

How long do tailgate gas struts last on a Dualis?
Typically 5–10 years, depending on climate and usage. Signs they’re due are a slow lift in cold weather, needing to be helped up, or the hatch drifting down. If one fails, replace both as a set.

Can owners replace Dualis tailgate struts at home?
Yes—if the tailgate is safely supported. It’s a quick job with basic tools: secure the hatch, pop the locking clips, swap the struts, and confirm full engagement on the ball studs. If in doubt, a workshop can do it during routine servicing.
