Parts for your 2007 Isuzu D-max-Gas struts

2007 Isuzu D‑Max gas struts: what’s fitted and what’s not

For the 2007 Isuzu D‑Max (first‑gen TFR/TFS, also sold locally as the RA Rodeo), factory gas struts are not used on the bonnet or the tailgate. Technical references that back this up include the Isuzu D‑Max Workshop Manual (Body section), which specifies a bonnet stay/prop rod rather than lift struts, and the Isuzu/GM Holden electronic parts catalogues for the RA platform that list a “hood stay” and tailgate support cables, with no OEM gas struts specified. Owner’s manuals for these models also instruct using a manual bonnet prop.

So why didn’t Isuzu fit gas struts from new? There are a few practical reasons that suited the ute’s brief here in Australia and New Zealand:

• Simplicity and reliability in dusty, off‑road conditions — a steel prop rod and tailgate cables handle grit and rough use better than sealed struts over the long haul.
• Lower cost and easier field service — fewer moving parts and no pressurised cylinders to fail when you’re a long way from town.
• Weight and packaging — the bonnet and tailgate on this generation weren’t designed around strut geometry, so cables and a prop are the straightforward solution.

That said, plenty of 2007 D‑Max owners choose aftermarket gas‑strut kits for the bonnet, and gas struts are common on accessories like canopies (rear door and side windows) and some soft tonneau frames. If struts are fitted as accessories, treating them as service items is smart.

Signs a gas strut is on the way out include slow lifting, the panel dropping in colder weather, oily film around the shaft, or having to “help” the panel through the first third of travel. When replacing, do both sides together so the lift is even. Match stroke length, compressed/extended lengths, end fittings (ball studs/eyelets), and the force rating (Newtons) recommended by the kit maker or canopy brand. In coastal areas, stainless shafts or corrosion‑resistant coatings are worth it. Keep the chrome shafts clean, don’t lubricate them with greasy sprays (they trap grit and damage seals), and avoid using the panel as a handle to climb into the tub — side loads can bend the struts or mounts.

If fitting a bonnet strut kit, follow the kit instructions and torque specs, use thread locker where called for, and recheck fasteners after the first week. For canopies, confirm hinge integrity, weak hinges make even fresh struts feel lazy.

Popular questions about 2007 Isuzu D‑Max gas struts

Does a 2007 D‑Max have factory bonnet gas struts?
From factory, no. The 2007 model uses a manual bonnet prop rod. This is documented in the workshop manual and parts catalogues, which list a hood stay rather than lift struts. If bonnet struts are present, they’ll be aftermarket.

Can gas struts be fitted to the bonnet or tailgate?
Yes, bonnet strut kits are available and make one‑handed lifting easier. The tailgate typically uses cables and hinges, some owners fit assist kits or torsion helpers rather than gas struts. Always choose a reputable kit designed for the RA‑series D‑Max/Rodeo to avoid panel misalignment or hinge stress.

What gas struts suit a canopy on a 2007 D‑Max?
It depends on the canopy brand and door size. Most canopy rear doors and side windows use medium‑force struts, the best bet is to read the canopy’s label on the strut (length and Newton rating) or check the canopy maker’s spec. When unsure, measure the old units (centre‑to‑centre, open and closed) and match the end fittings, then replace in pairs.
