Parts for your 2021 Toyota Rav4-Gas struts

2021 Toyota RAV4 gas struts: purpose, fitment and when to replace

Gas struts are indeed used on the 2021 Toyota RAV4. Toyota’s technical literature and parts catalogues for the XA50-series RAV4 list “Back Door Stay Assembly” units for the tailgate on manual-lift models, and a combination of a power back-door actuator (one side) plus a gas-charged stay (the other side) on vehicles with the powered tailgate. The bonnet on this model uses a support rod from factory, not gas struts. These details are documented in the Toyota RAV4 (XA50) Repair Manual body section and the Toyota Electronic Parts Catalogue entries for the back door stays and power back door components.

On a 2021 RAV4, the gas struts at the tailgate do the heavy lifting—literally. They’re nitrogen-charged dampers that counterbalance the rear door, making it easy to open and steady when parked at full height. Beyond convenience, they’re a safety feature, stopping the tailgate from dropping on a windy day or when the car’s on a slope.

Because gas pressure bleeds off slowly over time, these stays are wear items. Most owners will see 5–7 years of dependable service, though harsh heat, dust, and frequent use can shorten that. As part of routine servicing, it’s smart to check tailgate operation: does it rise confidently, hold at the top, and stay level left-to-right? A light wipe of the exposed rod with a clean, dry cloth keeps grit off the seals—avoid oil or silicone on the shaft, as that attracts dust and can damage the seals.

When replacement time rolls around, the workshop should always support the tailgate securely and renew struts in pairs on manual-lift gates for balanced force. On power back-door variants, the technician will replace the gas stay and inspect the powered actuator and hinges at the same time. Go for OE-spec or reputable aftermarket units matched to the RAV4’s tailgate weight
