Parts for your 2015 Nissan Pathfinder-Gas struts

2015 Nissan Pathfinder gas struts — what they do, and when to replace them

Based on technical references, gas struts are absolutely relevant to the 2015 Nissan Pathfinder (R52). The model uses gas‑charged lift supports on the rear tailgate/back door, including variants with a power tailgate where an electric actuator works alongside a gas strut. The bonnet, however, is held up by a prop rod rather than gas struts. Sources: Nissan Factory Service Manual (R52, 2015 – Body/Liftgate section), Nissan FAST parts catalogue listings for “Stay Assy–Back Door,” and aftermarket application guides for liftgate support struts.

On a 2015 Pathfinder, the rear gas struts do the heavy lifting of the tailgate so it opens smoothly and stays put without sagging. They’re sealed units filled with nitrogen and oil, which means no routine internal servicing — once they wear, they’re replaced. Aussie and Kiwi owners typically see 5–8 years out of a set, but coastal air, dust, heat, and frequent use can shorten that.

Common signs it’s time to swap them out include a hatch that’s slow to rise, won’t stay up, drops in cold weather, or needs a shove to get moving. If there’s any oily film around the shaft, that’s a giveaway the seal’s weeping.

When replacing, it’s best practice to do both sides together for even support. For power tailgate trims, follow initialisation steps after fitting (as outlined in the service manual) so the motor and strut are in sync. Use a prop or a helper — that tailgate’s heavier than it looks — and swap one side at a time. Stick with quality OEM or reputable aftermarket struts matched to the Pathfinder’s spec, especially if yours has the power tailgate hardware.

Care tips are simple:

• Keep the chrome shafts clean, a soft cloth does the job. Avoid grease or oil on the shafts — it attracts grit and can damage the seals.
• Open the tailgate gently, don’t force it if iced or jammed.
• Avoid adding weight like accessories to the tailgate without checking strut rating.

Note: The bonnet uses a prop rod, so bonnet “gas struts” aren’t applicable to this model year. If a hands‑free bonnet lift is desired, there are aftermarket conversion kits, but they’re not factory equipment.

Popular questions

How long do Pathfinder tailgate gas struts last?
Most owners get 5–8 years, but climate, usage, and exposure to dust or salt air can shorten that. If the hatch sags or needs help to open, they’re due. Replacing in pairs keeps lift and hold balanced.

Can I fit gas struts to the bonnet on a 2015 Pathfinder?
From factory, the R52 bonnet uses a prop rod. Aftermarket bonnet strut kits exist, but they’re a modification and need the correct brackets and hardware. They’re separate from the tailgate struts and don’t affect the power tailgate system.

Do power tailgate models use different struts?
Yes, trims with a power tailgate use components matched to the actuator system. Always order by VIN or exact spec. After fitting, run the tailgate initialisation procedure so the motor and strut operate correctly.
