2019 Toyota Vitz/Yaris Gas Struts — What They Do and When to Replace

Gas struts are absolutely relevant on the 2019 Toyota Vitz/Yaris hatch. Toyota’s own parts catalogue and service literature list the back door “stay” assemblies as gas-filled supports for the tailgate, and removal/installation procedures are included in the factory repair manual. Aftermarket catalogues also carry direct-fit tailgate lift supports for the 2019 Vitz/Yaris, which further confirms their use from factory. Note: the bonnet on most 2019 Vitz/Yaris models uses a simple prop rod, not gas struts.

On this model, the gas struts counterbalance the weight of the tailgate so it lifts smoothly and stays safely open. They’re sealed, nitrogen-charged units with a bit of internal oil for damping. As part of routine servicing, it’s smart to give them a quick once-over: a wipe to remove grime, a check for oil misting around the rod seal, and a feel test for smooth, even motion. There’s no scheduled replacement interval, but real-world life is often 5–10 years, and they’ll typically fade sooner in cold climates or if the tailgate is used heavily.

Because gas struts are sealed, they can’t be re-gassed or repaired reliably—replacement is the go-to fix. When the time comes, always replace them in pairs to keep lift and balance even. It’s a straightforward job: safely prop the tailgate, slip off the spring clips, pop the old struts off the ball studs, then click the new ones on. Avoid prying the rod or twisting the cylinder, and don’t grease the chrome rod (it attracts dust and damages seals). A light silicone wipe on the ball studs is fine.

Common signs it’s time to change the gas struts on a 2019 Vitz/Yaris tailgate include:

• Tailgate won’t stay up or drifts down, especially when it’s cold
• Slow or jerky opening/closing, or a heavy feel lifting the gate
• Visible oil film on the rod or at the seal, or bent/damaged hardware

For safety, if the gate sags or starts dropping, sort it promptly—no one wants a tailgate on their head. Fresh, quality struts bring back the light, tidy lift the Yaris is known for and keep daily use fuss-free.

Do the 2019 Vitz/Yaris have gas struts from factory?

Yes—on the hatchback’s tailgate. Toyota’s EPC and repair manual identify them as “back door stay” gas strut assemblies. The bonnet generally uses a prop rod rather than struts.

How long do the gas struts last, and when should they be replaced?

Many last 5–10 years. Replace when the tailgate won’t hold itself up, opens sluggishly, or shows oil at the seals. It’s best to replace in pairs for even performance.

Can Vitz/Yaris gas struts be re-gassed?

No. They’re sealed units. If performance drops, fit new struts—re-gassing isn’t reliable and usually costs more than straightforward replacement.
