Parts for your 2019 Toyota Mark x-Gas struts

2019 Toyota Mark X gas struts — what’s actually fitted from factory

For the 2019 Toyota Mark X (X13# series — GRX130/133/135), gas struts aren’t a factory item on either the bonnet or the boot. Toyota’s own technical literature backs this up: the Toyota Electronic Parts Catalog (EPC) for the GRX13# body group lists a bonnet support rod (prop rod) rather than a gas stay, and the boot lid is shown with torsion-bar hinges instead of gas dampers. The Toyota Repair Manual for the Mark X body section also details removal/installation procedures for the hood stay (prop rod) and trunk torsion bar hinge system, with no reference to gas struts for these closures.

Why did Toyota go this way in 2019? On sedans like the Mark X, torsion bars for the boot and a prop rod for the bonnet keep costs, weight, and packaging complexity down while delivering reliable counterbalance and consistent closing force. Gas struts are more common on hatchbacks, wagons, and some premium sedans where the opening panels are larger or need extra assist. The Mark X’s conventional sedan boot and relatively light bonnet don’t strictly need gas-assisted lifting to meet Toyota’s targets for usability and durability.

What does that mean for owners? Day to day, it’s business as usual: use the prop rod for bonnet support and enjoy a tidy boot space without strut towers intruding. There’s no gas-strut maintenance to worry about because none are installed from factory. As part of regular servicing, it’s worth:

• Lightly lubricating bonnet and boot hinges and the latch/catch points.
• Checking the bonnet prop rod grommet and retainer so it doesn’t rattle.
• Ensuring boot torsion bars are seated correctly and the boot opens evenly.

Keen on a smoother, one-handed lift? Aftermarket bonnet gas-strut kits exist for the GRX13# and can be a neat upgrade when fitted correctly. Just keep in mind:

• Pros: easier one-handed opening, nicer feel, reduced slam.
• Watch-outs: bracket alignment matters, some kits require drilling, and very stiff struts can stress bonnet edges if you push down off-centre.

Bottom line: from factory, the 2019 Mark X doesn’t use gas struts for the bonnet or boot. That choice is consistent with Toyota’s EPC and repair manuals for this model, and it suits the vehicle’s packaging and durability goals. Retrofit options are available if a gas-assisted feel is preferred.

FAQs

Does the 2019 Toyota Mark X have gas struts on the bonnet or boot?
From factory, no. Toyota’s Electronic Parts Catalog for the GRX13# series shows a bonnet support rod and torsion-bar boot hinges, and the repair manual procedures align with that. There are no OEM gas stays listed for either closure on 2019 builds.

Can gas struts be retrofitted to a 2019 Mark X bonnet?
Yes, several aftermarket kits are available for the GRX13#. A quality kit will include brackets matched to existing mounting points, struts sized for the bonnet weight, and clear instructions. Professional fitting is recommended to avoid panel misalignment or undue stress on the bonnet skin.

What maintenance applies if I retrofit gas struts?
Give the strut shafts a quick wipe to keep grit off the seals, avoid lubricants on the shafts themselves, and replace the pair if one weakens. Expect typical service life to vary with climate, heat and dust can shorten life. Always support the bonnet during replacement and check bracket torque after a few weeks.
