Parts for your 2013 Toyota Fortuner-Gas struts

2013 Toyota Fortuner gas struts: what they do and when to replace them

Referencing Toyota’s technical literature for the AN60-series Fortuner (2011–2015), including the Toyota Electronic Parts Catalogue and Body Repair Manual sections for “Back Door Stay,” the 2013 Fortuner is factory-fitted with two gas-charged lift supports on the tailgate. The bonnet on most markets uses a prop rod rather than gas struts, so “gas struts” on this model refers primarily to the rear tailgate units.

On a 2013 Toyota Fortuner, the tailgate gas struts do the heavy lifting. They counterbalance the back door so it opens smoothly, stays up without sagging, and closes without needing a shoulder workout. Being nitrogen-charged with internal oil for damping, they’re sealed components designed for years of reliable service in Aussie and Kiwi conditions.

Over time, seals age and the charge can drop, especially if the vehicle lives outdoors or carries accessories on the tailgate. That’s when owners start noticing the door creeping down or refusing to lift without a helping hand.

• Common signs they’re due: tailgate lifts slowly or won’t stay up, a hissing sound, oily film on the shaft, uneven lifting, or needing extra shove to close.
• Good practice: replace in pairs. Mismatched forces can twist the hinges and wear things out faster.

Service tips the workshop follows to keep Fortuner gas struts sweet:

• Keep the chrome shafts clean, wipe with a soft cloth. Don’t grease the shafts — it attracts grit and damages seals.
• During replacement, always support the tailgate with a prop or a mate. Swap one side at a time and ensure the ball sockets click home.
• Install with the shaft down where applicable — it keeps the internal seal lubricated and improves life.
• If the vehicle has added weight on the tailgate (spoiler, ladder, spare-wheel carriers), choose struts with the correct force rating to suit.

Most sealed struts aren’t meant to be re-gassed, replacement is typically the reliable fix. In normal use, expect 5–8 years, sometimes longer in mild climates. If the Fortuner’s tailgate feels lazy or sags on a hot day, it’s time. Fresh struts restore that factory “lift-and-hold” feel, reduce hinge strain, and make everyday use safer and easier — no head bumps, no dramas.

Does the 2013 Fortuner have gas struts on the bonnet?

From the factory, most 2013 Fortuners use a prop rod for the bonnet. The gas struts are on the tailgate. Aftermarket bonnet strut kits are available if hands-free bonnet lifting is desired.

How long do Fortuner tailgate gas struts usually last?

Typically 5–8 years, depending on climate, usage, and added tailgate weight. If the door won’t stay up or needs help to lift, replace them in pairs for best results.

Can they be re-gassed, or should they just be replaced?

Most OEM-style struts are sealed and are best replaced. Some local specialists offer re-gassing, but longevity can vary. New, correctly rated struts are generally the most dependable option.
