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, if equipped with height memory, set the preferred opening height afterwards.

There’s virtually no routine maintenance needed—just keep the rod clean and dry. Don’t grease the rod or spray silicone on it, as that can swell seals and shorten life. Avoid using the tailgate as a handle when closing, pull from the inner grab strap instead to reduce side load on the struts.

With quality aftermarket or OEM struts, most owners can expect 5–10 years of service depending on climate and use. If the tailgate won’t hold itself up or the power unit seems to struggle and beep, fresh struts are often the cheapest, quickest fix. Given the safety angle—no one loves a tailgate to the head—this is one of those small jobs that makes a big difference.

Popular questions about 2008 Honda Odyssey gas struts

Do all 2008 Odyssey models have gas struts?
All trims use gas-charged supports on the rear tailgate, including power and manual liftgates. The bonnet is held up by a prop rod rather than gas struts.

What are the signs my Odyssey’s gas struts are failing?
If the tailgate sags, won’t stay up, needs help to lift, or drops faster in cold weather, the struts have likely lost charge. Oily residue on the rod or a slight hiss during movement can also indicate seal wear.

Can I replace Odyssey tailgate struts at home?
Yes. With the tailgate safely supported, each strut typically pops off and on via small retaining clips at the ends. Replace both sides, and on power models, fully cycle the tailgate afterwards. If anything binds or the door is misaligned, have a technician check hinges and calibration.
