2009 Mazda BT-50 Gas Struts — What’s Fitted and What’s Not

For the 2009 Mazda BT-50 (UN series), gas struts aren’t a factory-fitted item for the main body panels. The bonnet uses a traditional support rod, and the tailgate is supported by cables rather than struts. This setup is documented in technical references including the Mazda BT‑50 (UN, 2006–2011) Workshop Manual under Body—Hood (bonnet stay/support rod specified), and mirrored in the Ford Ranger PJ/PK workshop documentation, given the shared platform. Mazda Genuine Accessories literature of the period shows gas struts only on optional gear like hard tonneau lids and canopy windows, not the base vehicle’s bonnet or tailgate.

Why the absence of gas struts on the standard BT‑50? It comes down to simplicity, durability, and cost for a hard-working ute. A steel bonnet prop and cable-supported tailgate are rugged, low-maintenance solutions that handle dust, mud, corrugations, and rough-site use without the potential leak-down or seal wear that can affect pressurised struts over time. For fleets and tradies, fewer moving parts also means fewer surprises during servicing and fewer replacements in harsh conditions.

Owners will commonly see gas struts on accessories: a factory or aftermarket hard lid over the tub, some canopies, and certain toolboxes. Those struts make opening and holding the lid or window safer and easier, and they’re serviceable parts—replaced in pairs when lift assistance drops off or the lid no longer stays up.

• Bonnet: OEM design uses a support rod (no gas struts from factory).
• Tailgate: OEM design uses support cables (no gas struts from factory).
• Accessories: Hard lids and canopies may use gas struts, these are serviced as needed.

If fitting aftermarket bonnet struts or a tailgate assist kit to a 2009 BT‑50, choose hardware designed for the UN series, confirm mounting points are reinforced, and follow torque specs from the kit maker. For hard lids and canopies, replace struts in pairs when the lid sags, needs a big shove to open, or shows oil misting. In dusty Aussie and Kiwi conditions, wipe strut shafts clean now and then to protect seals, and avoid using them as grab handles. A quick lift-test at each service is usually enough to catch weak struts before they become a safety risk.

FAQs

Did a 2009 Mazda BT-50 come with bonnet gas struts from factory?
No. The 2009 BT‑50 uses a bonnet support rod as specified in the workshop manual. Gas struts on the bonnet are an aftermarket add-on, not an OEM part.

Can gas struts be added to the BT-50 bonnet or tailgate?
Yes, aftermarket kits exist for the bonnet and tailgate assist. Use vehicle-specific kits for the UN series, follow the instructions closely, and check clearances and fasteners after the first few drives.

Where will I find gas struts on a BT-50?
Typically on accessories: hard tonneau lids and canopy rear windows often use gas struts. These are consumables—replace them in pairs when lift assistance fades or the lid won’t stay up.
