Parts for your 2019 Lexus Is-Gas struts

2019 Lexus IS gas struts — used or not?

Based on technical references, the 2019 Lexus IS (XE30 series) is not factory-fitted with gas struts on the bonnet or the boot. The Lexus Owner’s Manual for the 2019 IS specifies a support rod to hold the bonnet open, not gas struts. The boot uses gooseneck hinges with torsion assistance rather than external gas struts. The Toyota/Lexus Electronic Parts Catalogue (EPC) lists a “hood support rod” and hinge/torsion components for the luggage compartment, with no gas-filled lift supports shown. Lexus repair manual procedures (TIS) for bonnet and boot service likewise describe the support rod, hinge and torsion hardware, and do not include gas-strut removal/refit steps.

Why no gas struts? It’s largely a design and packaging decision. A simple support rod for the bonnet is light, inexpensive, and very reliable over time. For the boot, torsion-assisted gooseneck hinges give a consistent opening and closing feel and keep the hardware tucked away, preserving luggage space and trim fit. This setup also reduces parts count and service complexity, which suits long-term durability in Aussie and Kiwi conditions.

What does that mean for owners? If the bonnet needs to be held up, it’s the standard support rod doing the job, if the boot action feels firm or progressive, that’s the torsion springing at work, not gas struts. There’s nothing to “re-gas” on this model. Routine servicing focuses on simple checks rather than strut replacement.

• Inspect the bonnet support rod clip and pivot for wear, replace the clip if it’s loose or brittle.
• Lightly lubricate bonnet and boot hinge pivots with a suitable lubricant to keep movement smooth.
• If the boot feels heavy or pops too aggressively, have a technician assess hinge alignment and torsion preload rather than looking for failed gas struts.
• Considering a bonnet strut retrofit? Aftermarket kits exist, but ensure they’re engineered for the XE30 body and won’t stress the bonnet or guard mounts. Professional fitment is recommended to avoid panel distortion.

Bottom line: for a 2019 Lexus IS, “gas struts” aren’t a factory part of the bonnet or boot. The car uses robust mechanical supports that rarely need more than occasional inspection and a dab of lube.

Popular questions

Does the 2019 Lexus IS have gas struts on the bonnet or boot?
No. The factory setup uses a bonnet support rod and torsion-assisted gooseneck hinges for the boot. There are no gas-filled lift supports to service or replace.

Can gas struts be retrofitted to the bonnet on a 2019 Lexus IS?
Yes, aftermarket bonnet strut kits are available. Choose a kit designed for the XE30 and have it installed carefully to avoid stressing the mounting points. Keep in mind modifications may affect warranty or insurance, so it’s worth checking first.

What should be serviced if the boot or bonnet feels stiff or heavy?
For this model, look to hinge lubrication, alignment, and the bonnet support rod clip. If the boot action has changed, a technician can assess hinge condition and torsion assistance rather than chasing non-existent gas struts.
