Parts for your 2008 Holden Colorado-Gas struts

2008 Holden Colorado Gas Struts

Based on technical sources, gas struts are not factory-fitted or required on the 2008 Holden Colorado (RC). The bonnet is supported by a steel prop rod, and the drop-down tailgate uses conventional hinges without lift supports. This is confirmed by the Holden Colorado RC Workshop/Service Manual (Body—Hood/Bonnet section), the GM Holden Electronic Parts Catalogue listings for bonnet support hardware, and the shared-platform Isuzu D‑Max (TFR/TFS, 2007–2012) service documentation. Major lift-support catalogues (e.g., Stabilus Lift-O-Mat and Monroe Max-Lift) also show no OEM bonnet gas-strut application for this model.

Why isn’t it fitted from factory? For a ute like the 2008 Colorado, there’s no liftgate or hatch that needs struts, and a prop rod is a simple, robust solution for the bonnet—ideal for dusty, corrugated-road conditions common in Australia and New Zealand. It keeps costs down, avoids seals and shafts that can foul with grit, and makes servicing straightforward.

There’s one common exception: accessories. Many Colorados run a canopy or hard lid over the tub, and those usually rely on gas struts to hold up the glass or lid. Those struts are accessory items rather than Colorado factory parts, but they do need periodic attention.

• Tell-tales a canopy or hard-lid strut is tired: the glass/lid won’t stay up, it sags in cool weather, or there’s an oil weep on the strut body.
• Typical maintenance: keep the rod clean, don’t lube it with grease (it attracts grit), and replace in pairs when lift starts to fade.
• Replacement tips: match overall length and end fittings, and use the Newton rating printed on the old strut as a guide. Support the lid safely before swapping.

Owners keen on bonnet gas struts can fit aftermarket kits designed for the RC Colorado. Quality kits usually bolt to existing points, avoid drilling, and retain the prop rod as a backup. Always choose stainless or coated hardware to handle coastal and off-road conditions.

Popular questions about 2008 Holden Colorado gas struts

Does a 2008 Holden Colorado have bonnet gas struts from factory?
From factory, no. The RC-series Colorado uses a bonnet prop rod. If gas struts are present, they’ve been added as an aftermarket kit.

Can gas struts be added to the bonnet or tailgate?
Bonnet: yes, with a model-specific kit. Tailgate: most owners install a damper or assist spring rather than full gas struts. Choose parts built for the RC to avoid interference with wiring and liners.

How long do canopy gas struts last on a Colorado?
Typically 3–7 years, depending on heat, dust and use. Frequent off-road driving and coastal air shorten life. Replace in pairs when lift weakens or the glass won’t stay up unaided.
