Parts for your 2008 Honda Odyssey-Gas struts

2008 Honda Odyssey gas struts — what they do and when to replace them

Yes, gas struts are used on the 2008 Honda Odyssey. Honda’s Factory Service Manual for the 2005–2010 Odyssey (Body—Tailgate section) specifies liftgate support struts, and Honda’s parts catalogue lists them as “Stay, Tailgate” (gas‑charged supports) for this model. The bonnet uses a manual prop rod, but the rear tailgate relies on a pair of gas struts to hold it up and assist lifting.

On a 2008 Odyssey, the tailgate is big and fairly heavy. The gas struts counterbalance that weight so the door opens smoothly and stays put overhead without needing two hands or a gym membership. On power tailgate variants, the struts share the load with the motor so the system doesn’t strain every time you open up.

Over time, seals wear and nitrogen charge bleeds off. That’s when the tailgate starts dropping, needs a shove to rise, or sags in colder weather. Oil mist on the shiny shaft or a faint hiss can also be giveaways. When any of that shows up, it’s time for replacement.

• Always replace gas struts in pairs to keep lift and balance even.
• Support the tailgate securely with a prop or a helper before removing a strut.
• Most Odyssey struts use ball-stud ends with spring clips—pry the clip just enough to release, swap the strut, and click it back on.
• On power tailgate models, cycle the door fully open and closed after fitment to let the control unit relearn effort
