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
