Parts for your 2012 Isuzu D-max-Gas struts

Are gas struts used on the 2012 Isuzu D‑MAX?

Short answer: they aren’t factory-fitted. For the 2012 Isuzu D‑MAX (RT series), the bonnet is supported by a manual prop rod and the tub tailgate is cable-supported with standard hinges, not gas struts. This setup is documented in the Isuzu D‑MAX Owner’s and Driver’s Manual (RT, MY12), which describes using the bonnet support rod rather than any lifter mechanism, and in the Isuzu UTE Australia electronic parts listings for the 2012 RT series, which show a bonnet stay and clip, plus tailgate cables and hinges, but no gas lifters. The workshop body section likewise details tailgate cables and a prop-rod bonnet. Factory canopies weren’t standard on this model, aftermarket canopies use gas struts on the lift-up glass, but that’s an accessory rather than a vehicle gas strut.

Why didn’t Isuzu fit gas struts from new? It’s a practicality and durability call typical of work utes from that era. A prop-rod bonnet and cable-supported tailgate are tough, low-cost and reliable in dusty, wet and rough conditions—exactly where many D‑MAX utes live. Keeping the design simple also reduces service costs for fleets and tradies.

• Bonnet: manual prop rod from factory, no gas struts listed in OEM parts or service literature.
• Tailgate: hinge-and-cable setup, no OEM gas strut or torsion assist on 2012 models.
• Accessories: canopy glass commonly uses gas struts, but that’s aftermarket or dealer accessory, not the base vehicle.

Owners who want an easier lift can fit aftermarket bonnet strut kits or tailgate assist gas struts. Quality kits mount to existing points, preserve alignment, and make day-to-day use more pleasant. For anyone adding them, it’s smart to choose corrosion-resistant hardware, torque bolts to spec, and check clearances with tub liners and tonneau covers. On canopies, gas struts eventually lose pressure, tell-tales include glass not staying up or a slow, jerky lift. Replacement is straightforward: match end fittings, extended length and force rating to the canopy brand.

Bottom line: the 2012 D‑MAX doesn’t use gas struts from factory on the bonnet or tailgate, but owners often retrofit them for convenience—especially on work utes that see constant tailgate or canopy use.

FAQs

Does a 2012 D‑MAX have bonnet gas struts from factory?
From new, no. The 2012 RT series uses a bonnet prop rod. This is reflected in the owner’s manual and OEM parts listings, which show no gas lifters for the bonnet.

Can a 2012 D‑MAX tailgate be fitted with gas struts (tailgate assist)?
Yes. Aftermarket tailgate assist kits with gas struts are popular and reduce the effort and speed of the drop. Good kits include brackets that work with the factory hinges and cables. Check compatibility with tub liners and tonneau/ute lids before buying.

My canopy glass won’t stay up—are the gas struts gone?
Likely. Canopy lift windows use small gas struts that lose charge over time. If the glass sags or needs help to lift, replace them with the correct length and force rating specified for the canopy brand and window.
