Parts for your 2013 Toyota Mark x-Gas struts

2013 Toyota Mark X gas struts — are they used on this model?

For the 2013 Toyota Mark X (GRX130/133 series), gas struts were not fitted from factory to either the bonnet or the boot. The OEM setup uses a bonnet prop rod (hood stay) and torsion bars on the boot lid. This configuration is confirmed by technical references that list and illustrate the original parts for this model year and chassis code.

Technical sources referenced to reach this conclusion include:

• Toyota Electronic Parts Catalogue (EPC) for GRX130/133: Hood assembly shows a “hood stay” (prop rod) and no gas damper, luggage compartment section lists torsion bar/hinge hardware with no gas stay parts.
• Toyota body mechanical/service literature for Mark X: procedures describe the hood stay and boot torsion bar handling and adjustment, not gas struts.
• OEM parts diagrams used by genuine-parts catalogues for 2013 Mark X: diagrams display the prop rod and boot torsion bars, with no gas strut callouts.

Why no gas struts? Toyota engineered this sedan with a robust, low-maintenance setup. A prop rod is lighter, cheaper to service, and leaves more under-bonnet packaging space. In the boot, torsion bars counterbalance the lid reliably without the long-term pressure loss that can affect gas struts. For a model focused on durability and value, it’s a sensible factory choice.

That said, some owners in NZ and Australia do retrofit gas struts to the bonnet or boot for convenience. If going down that path, pick a kit built specifically for the GRX130/133 hinge geometry, use stainless or corrosion-protected brackets, and confirm the force rating so the bonnet doesn’t lift too aggressively or stress the hinges. Always follow torque specs and recheck clearances with the bonnet or boot fully open and closed.

Want to double-check what’s on the car? Pop the bonnet and you’ll see either a single stay rod clipped near the radiator support (factory), or a pair of dampers mounted near the hinges (aftermarket). At the rear, a factory Mark X boot uses torsion bars across the hinge line—no gas cylinders present.

• Can it be upgraded? Yes, but choose a reputable kit, and be aware it’s a modification, not an OEM part.
• Safety tip: Boot torsion bars are under heavy preload—don’t remove them without the correct procedure and tools.

Popular questions about 2013 Toyota Mark X gas struts

Do 2013 Mark X sedans have gas struts from factory?
From the factory, no. The 2013 Mark X uses a bonnet prop rod and boot torsion bars. If you see gas struts on your car, they’ve almost certainly been added later as an aftermarket upgrade.

Can gas struts be retrofitted to the bonnet or boot?
Yes. Quality retrofit kits exist for the bonnet, and some custom options are available for the boot. Use vehicle-specific brackets, match the strut force to the panel weight, and check that nothing fouls on opening/closing. It’s best installed by a competent tech if you’re unsure.

How do I know if my boot or bonnet support needs attention?
If the bonnet won’t stay up on the prop rod, the issue is usually with the clip or rod seating, not a strut. For the boot, signs of weak torsion bars include the lid dropping faster than normal or not staying open on a slope. Hinge wear can also cause misalignment or creaking.
