Parts for your 2021 Toyota Land cruiser-Gas struts

2021 Toyota Land Cruiser gas struts — what they do and when to replace them

Gas struts are absolutely used on the 2021 Toyota Land Cruiser. Technical references such as the Toyota Owner’s Manual and Repair Manual for the 200/300 Series, along with Toyota’s Electronic Parts Catalogue (EPC), list gas-charged “stay assemblies” for the rear liftgate/tailgate, and bonnet supports on some grades/markets. That means the 2021 Land Cruiser relies on gas struts to hold the upper tailgate/liftgate safely, and in certain variants to support the bonnet as well.

On a big rig like a Land Cruiser, gas struts do the heavy lifting quietly in the background. They counterbalance the weight of the liftgate so it opens smoothly, stays put on the beach or at the job site, and doesn’t crash down when the wind picks up. Where fitted to the bonnet, they make checks under the bonnet easier and safer, especially on uneven ground. On LC300 models with a powered tailgate, the power unit still uses gas struts to manage weight and motion.

They don’t have a set replacement interval, but they do wear out. Typical signs a replacement is due include:

• Liftgate or bonnet doesn’t hold itself up, sags, or drops suddenly
• Needing two hands or a big shove to open
• Greasy film or damping oil weep on the rod or cylinder
• Temperature sensitivity — fine in summer, weak in winter mornings

For servicing, a quick strut check should be part of every Land Cruiser’s routine. Open and close the tailgate a few times, stop it mid-travel, and see if it holds steadily. Inspect the shafts for nicks and grime. Wipe the chrome rods clean with a soft cloth — don’t lubricate them, as oil and silicone attract grit and can damage the seals. If one rear strut is weak, replace them as a pair to keep lift forces even. Always support the tailgate/bonnet with a prop during replacement, and mind fingers near ball joints and clips.

When ordering, match by VIN to ensure the correct pressure rating and end fittings for your exact 2021 Land Cruiser (LC200 split tailgate or LC300 one-piece/powered tailgate). Quality OE or reputable aftermarket struts fitted in the correct orientation (rod-down unless specified otherwise) will restore that smooth, confidence-inspiring lift Land Cruiser owners expect.

Popular questions about 2021 Toyota Land Cruiser gas struts

Do all 2021 Land Cruisers use gas struts on the bonnet?
Many 200 Series vehicles and some markets of the 2021 range have gas struts for the bonnet, while others use a prop rod. All variants use gas struts on the liftgate/tailgate. The sure-fire way is to check your vehicle or confirm via the VIN in the Toyota EPC.

How long do the rear tailgate gas struts typically last?
It varies with climate and use, but 5–10 years is common. Frequent heavy tailgates, dust, and cold temps can shorten life. If the gate won’t stay up or slows right down in winter, it’s time to replace.

Can weak gas struts damage the powered tailgate on LC300?
Yes — weak struts can make the power unit work harder, increasing noise and stress. Replacing tired struts promptly helps the motor, hinges and latch live longer and keeps the motion smooth and quiet.
