Parts for your 2013 Lexus Is-Gas struts

2013 Lexus IS gas struts — what’s actually fitted

For the 2013 Lexus IS sedan range (IS250/IS350 and IS F, chassis codes GSE2#/USE20) sold in Australia and New Zealand, factory gas struts are not fitted to the bonnet or the boot. This isn’t guesswork: the Lexus IS Owner’s Manual for MY2013 shows a bonnet support rod, the Lexus IS Repair Manual (GSE2#/USE20 series) details a prop-rod bonnet setup, and the Toyota/Lexus Electronic Parts Catalogue lists a “support rod” for the bonnet and torsion bars for the luggage compartment lid, not gas-charged lift supports. The IS C convertible uses powered roof hardware with dedicated actuators and dampers, but not the usual serviceable “gas struts” you’d see on a hatch or wagon.

Why no gas struts on the 2013 IS? Lexus engineered the sedan with a simple, durable approach for the bonnet and boot. A prop rod and torsion bars are robust, reliable for the life of the car, and lighter and cheaper than a pair of gas struts and reinforced mounting points. They also free up packaging space around the strut towers and guards, which is handy given the tight engine bay on the V6 and the structural bracing on the IS F.

• Simplicity and reliability: a prop rod and torsion bars rarely fail and need no routine servicing.
• Weight and packaging: gas struts add hardware and require reinforced mounts, the IS uses that space for other components.
• Cost and longevity: the factory setup keeps costs down without compromising day-to-day usability.

Owners who want a one-hand bonnet lift can retrofit aftermarket gas strut kits. Just note these are not OEM: quality varies, install points may sit on the guard/bonnet hinges, and incorrect fitment can tweak bonnet alignment. If retrofitting, use corrosion-resistant ball studs, torque them correctly, and re-check panel gaps after installation.

Does the 2013 Lexus IS have gas struts on the bonnet or boot?

No. The 2013 IS250/IS350 sedan and IS F use a bonnet support rod and boot torsion bars. The IS C convertible’s powered roof uses actuators and dedicated dampers, not the common serviceable gas struts found on hatchbacks.

Can gas struts be retrofitted to the bonnet?

Yes, aftermarket bonnet strut kits exist and can make the bonnet easier to lift. Choose a kit designed for the GSE2# chassis, follow torque specs, and confirm the strut force suits alloy or steel bonnet variants. After fitting, check bonnet latch engagement and panel gaps.

Is there any maintenance if gas struts are retrofitted?

If aftermarket gas struts are installed, keep the chrome shafts clean and dry, avoid petroleum sprays on the seals, and replace pairs together if they sag, bind, or leak oil. Expect a service life of several years, depending on quality and climate.
