Parts for your 2020 Toyota Hilux-Gas struts

Are gas struts used on the 2020 Toyota Hilux?

Short answer: from factory, no. On the 2020 Toyota Hilux (AN120/AN130 series), Toyota supplies the bonnet with a mechanical support rod rather than gas struts, and the tub tailgate is unassisted. This is shown in the Toyota Hilux Owner’s Manual (2020), which instructs drivers to raise the bonnet and hold it with the support rod, and in the Toyota Electronic Parts Catalogue, which lists a “Stay, Hood” (prop rod) rather than any gas strut assemblies for the bonnet. Toyota’s Genuine Accessories material for the same model year offers a “Tailgate Assist” kit as an accessory, indicating it isn’t standard fitment and uses a damper/assist mechanism only when specified.

Why hasn’t Toyota fitted gas struts as standard on the 2020 Hilux? It’s largely about simplicity, durability and cost. A prop rod is robust in dusty, muddy and high-vibration conditions common across Australia and New Zealand, it’s inexpensive, and it avoids the service life and temperature sensitivity issues that gas-charged struts can have on work utes that see a lot of outback or site duty. Keeping the tailgate unassisted also reduces weight, complexity and potential wear points for vehicles that regularly cop heavy use.

That said, plenty of Hilux owners want the convenience of struts, and there are solid options:

• Aftermarket bonnet strut kits designed for AN120/AN130 Hilux, with brackets that use existing mounting points.
• Tailgate assist kits (damper or torsion-assisted) to reduce the drop and make lifting easier.
• Gas struts commonly fitted to accessory canopies, side windows and hard tonneau lids (these are accessory components rather than factory vehicle parts).

If adding gas struts, choose kits engineered for the 2020 Hilux, check clearance with snorkels/bull bars where relevant, and follow torque specs. Expect struts on canopies and hard lids to need replacement every few years depending on usage, dust exposure and temperature swings. If a strut no longer supports the panel, feels oily, or squeaks/binds, it’s time to replace in pairs to keep even lift and closing force.

• Can gas struts be fitted to a 2020 Hilux bonnet or tailgate?
  Yes. Aftermarket bonnet strut kits and tailgate assist dampers are widely available for the AN120/AN130 Hilux. They use model-specific brackets and are generally a straightforward DIY fit with basic tools.
• How long do gas struts on canopies or hard lids typically last?
  Anywhere from 3–7 years is common, depending on heat, dust and how often the panel is opened. If the lid drops, won’t stay up, or the strut shows oil misting, replace both sides together.
• Do factory manuals show gas struts on the 2020 Hilux bonnet?
  No. The Toyota Owner’s Manual for this model shows a bonnet support rod procedure, and Toyota’s parts catalogue lists a hood “stay” rather than strut assemblies for the bonnet.
