Parts for your 2016 Holden Colorado-Gas struts

2016 Holden Colorado gas struts — are they used and should owners worry about them?

Checking against technical references for the MY16 RG-series Colorado — including the Holden/GM factory workshop manual and the GM Electronic Parts Catalogue (EPC) for the 2012–2016 platform — the bonnet is supported by a manual prop rod (not gas struts), and the tub tailgate uses hinge pivots and support cables (again, not gas struts). Holden Genuine Accessories literature for the same model year only specifies gas struts for optional hard tonneau lids and canopies. So, gas struts are not a factory-fitted service item for the 2016 Holden Colorado’s bonnet or tailgate, they’re only relevant when a vehicle has an accessory hard lid or canopy.

Why didn’t Holden fit gas struts from the factory? It comes down to simplicity, durability and cost. A steel prop rod is basically bomb-proof in dust, mud and rough ute life, adds almost no weight, and is easy to service in the field. For the tailgate, the tried-and-true cable system is robust and cheap to replace. It also avoids extra moving parts down the back where grit and road spray live. Many owners who want a lighter-feeling tailgate or hands-free bonnet fit aftermarket strut kits, but that’s a preference call rather than a factory requirement.

If the Colorado does have accessory gas struts (hard lid or canopy), they’re worth a quick look during regular servicing. Keep the chrome shafts clean, don’t grease them (that attracts grit and chews the seals), and replace in pairs if one weakens. Signs they’re on the way out include the lid dropping, needing a helping hand to open, slow or uneven motion, or a mist of oil at the rod seal. Struts usually last a few years depending on heat, use and load, lids with added racks or gear can shorten that lifespan. When replacing, match the Newton rating, overall length and end fittings specified by the accessory maker (e.g., Holden Genuine, EGR, Aeroklas). Always support the lid with a prop before you pop the clips, and check that mounting brackets are tight after install.

• Factory fitment: bonnet prop rod, tailgate cables — no OE gas struts
• Accessories that do use struts: hard tonneau lids and canopies
• Maintenance tip: clean shafts, don’t lubricate, replace in pairs if weak

Popular questions about 2016 Holden Colorado gas struts

Can gas struts be added to the bonnet?
Yes. Aftermarket bonnet strut kits exist for the RG Colorado and usually use bolt-on or rivnut brackets at the guard and bonnet. Some kits require drilling, others don’t. Check compatibility with snorkels, under-bonnet accessories and bullbar clearances, and follow torque specs supplied by the kit maker. If in doubt, have a workshop fit and align it so the bonnet shuts cleanly and latches properly.

What struts do I need for a hard lid or canopy?
It depends on the brand and exact accessory. Genuine Holden lids and common canopies (EGR, Aeroklas, Utemaster, etc.) use specific lengths, end fittings and gas ratings. Read the label on the old strut, measure extended/compressed length, and match the Newton rating. Replace both sides together to keep lift smooth and even, especially if the lid carries a rack or accessories.

How long do gas struts last, and when should they be replaced?
Typically 3–7 years, depending on climate, usage and load. Replace them when the lid sags, needs help to open, slams shut, or shows oil weep at the seal. Cold mornings can make weak struts feel worse, if they’re marginal, they’ll usually get worse over time. Always support the lid during replacement.
