Parts for your 2021 Honda Odyssey-Gas struts

2021 Honda Odyssey gas-struts: what they do and when to replace them

Based on Honda’s 2021 Odyssey service information (Body/Doors – Tailgate and Power Tailgate System) and the Honda genuine parts catalogue for this model series, the vehicle uses gas‑pressurised struts on the rear tailgate. The bonnet is supported by a prop rod (no gas struts), so gas‑struts are relevant to the tailgate only.

On the 2021 Odyssey, the tailgate gas‑struts counterbalance the weight of the door so it lifts smoothly and stays safely open. On power tailgate variants, they work alongside the electric drive to control opening speed and reduce motor load. That means easier access for the family and less strain on the power tailgate hardware.

There’s no fixed replacement interval for these struts
