Parts for your 2017 Toyota Mark x-Gas struts

2017 Toyota Mark X gas struts — are they actually used?

Short answer: factory gas struts aren’t fitted to the 2017 Toyota Mark X’s bonnet or boot, so the “gas-struts” part category isn’t relevant for this model as delivered. Toyota’s own technical documentation backs this up. The Toyota Electronic Parts Catalogue (EPC) for the GRX130 series (2016–2019) lists a Hood Stay Sub‑Assembly (a manual prop rod) for the bonnet, and a Luggage Compartment Door Torsion Bar setup for the boot. Likewise, the Body/Exterior sections of the Mark X repair manual illustrate a bonnet stay and torsion bar counterbalance for the boot, with no gas lift supports shown or specified. That means there are no OEM bonnet or boot gas struts to replace on a stock 2017 Mark X.

Why the absence of gas struts? Toyota engineered the Mark X as a traditional sedan with a separate boot lid. On this layout, compact torsion bars neatly counterbalance the boot without intruding into the luggage area, while a simple bonnet stay keeps weight, cost, and long‑term service risk down. Gas lift supports add convenience, but they do wear and lose pressure over time, a prop rod and torsion bars are robust, predictable, and easy to assemble on the line.

It’s also worth clearing up a common mix‑up: while many shock absorbers are “gas‑charged”, they are part of the suspension and not the same thing as bonnet or boot gas lift struts. In Toyota documentation, those lift supports are usually called “lift supports” or “dampers”, the Mark X doesn’t list them for bonnet or boot from factory.

Aftermarket options do exist. Owners sometimes retrofit bonnet dampers or boot lift supports using bracket kits. If going that route, it’s smart to:

• Choose kits specifically designed for GRX130 hinge geometry.
• Avoid mixing torsion bars with additional boot struts unless the kit instructions say so—over‑assist can stress hinges.
• Check clearance with washer hoses, wiring, and the bonnet’s closing line before committing.

Servicing tip for workshops: because there are no OEM gas lift supports on the bonnet or boot, there’s nothing to “re‑gas” or swap as part of routine service on a stock Mark X. Instead, include a quick check that the boot torsion bars still hold the lid and that the bonnet stay, grommets, and latch points are secure and lubricated. If a customer has an aftermarket kit, assess strut force, end‑fittings, and mounting brackets for wear or play, and replace in pairs if performance has dropped.

Does the 2017 Mark X have factory bonnet or boot gas struts?

No. Toyota specifies a bonnet prop rod (Hood Stay Sub‑Assembly) and a torsion bar counterbalance for the boot. The EPC and body repair manual drawings for the GRX130 series do not show any lift supports for bonnet or boot from factory.

Can gas struts be retrofitted to the Mark X bonnet or boot?

Yes, with aftermarket kits. Use vehicle‑specific brackets, verify clearance, and don’t over‑assist the boot. If the kit replaces torsion bars, follow the kit instructions carefully and replace supports in pairs for balanced operation.

Are the Mark X’s “gas struts” the same as its suspension shocks?

No. Gas‑charged shocks/dampers in the suspension are a different component. “Gas struts” in parts listings usually mean bonnet/boot lift supports, which the 2017 Mark X doesn’t have as OEM equipment.
