2019 Toyota HiAce Gas Struts: What’s Fitted and How to Look After Them

Based on technical references, gas struts are relevant to the 2019 Toyota HiAce (H300) for models with a lift-up back door (tailgate). Toyota’s Repair Manual for HiAce H300 (Body Mechanical — Back Door) specifies gas-filled “stay assemblies” supporting the tailgate, and the Toyota Electronic Parts Catalogue lists a “Stay Assembly, Back Door” for tailgate-equipped variants. The Bonnet (Hood) section of the same manual specifies a prop rod, not gas struts. Rear swing-out “barn door” models use hinges and check straps, not gas struts. Aftermarket catalogues from major lift-support makers also list tailgate gas struts for 2019-on HiAce, reinforcing this fitment pattern.

For those HiAce vans and buses with a lift-up tailgate, the gas struts do the quiet heavy lifting—literally. They counterbalance the door’s weight so it pops up smoothly and stays put without a wrestling match. That means safer loading, fewer head knocks, and less stress on hinges and the door shell.

They’re sealed, nitrogen-charged units, so there’s no routine “topping up”. Servicing is more about inspection and timely replacement. Tell-tale signs they’re getting tired include the tailgate dropping in cool weather, rising slowly, needing a hand to start moving, or a light film of oil around the rod seal. If any of that shows up, it’s time to sort them—ideally as a pair so lift is balanced and the hinges aren’t twisted.

• Safety first: always support the tailgate before removing a strut. A prop or an assistant is non‑negotiable.
• Clean, don’t grease: keep the chrome rod clean and dry, avoid oil or silicone sprays on the rod itself as they attract grit and can damage seals.
• Joints only: a tiny dab of silicone-safe lubricant on the ball-stud pivots is fine if they creak, keep it off the rod.
• Temperature matters: struts feel weaker in cold weather. If they only fail in winter, they’re on the way out.
• Accessories count: rear ladders, spare-wheel mounts or added glass can tip the balance, consider correct uprated struts if extra mass is fitted.

Replacement is straightforward: verify the body style (tailgate vs barn doors), match the strut length, end fittings and force rating to the VIN, and click new units onto sound ball studs. Don’t drill, heat, or “re‑gas” sealed struts—most modern units are not serviceable. Dispose of old struts responsibly as pressurised items. With fresh, correctly rated struts, the HiAce tailgate behaves as it should—easy to lift, steady overhead, and less wear on everything around it.

FAQs

Does every 2019 Toyota HiAce have gas struts?
Not all of them. Tailgate (lift-up back door) variants use gas struts. Models with twin rear swing-out barn doors don’t use gas struts at the back, and the bonnet uses a prop rod.

Can the HiAce’s gas struts be re-gassed, or should they be replaced?
Most OEM and quality aftermarket struts for the H300 are sealed units and aren’t designed to be re-gassed. If they’re weak, leaking, or not holding the door, replacement is the reliable fix—ideally both sides together.

What strut force or size does my HiAce need?
It depends on body style, tailgate glazing, and any accessories. Use the VIN to match OEM spec in the parts catalogue, or select reputable aftermarket units that list direct compatibility for 2019-on HiAce H300 tailgates.
