Parts for your 1989 Toyota Hilux surf-Gas struts

1989 Toyota Hilux Surf gas struts — are they fitted or relevant?

For the 1989 Toyota Hilux Surf (N130 series), factory gas struts aren’t part of the original setup. Toyota’s own technical documentation backs this up: the factory service manual for the N130 body sections (Hood and Rear Body) specifies a simple bonnet support rod, and the rear of the vehicle is a drop-down tailgate with a power window built into it—there’s no liftback or hatch to require gas stays. The Toyota Electronic Parts Catalogue for the same series lists a “hood stay” (prop rod) and tailgate hardware, but no lift supports for bonnet or “back door.” This layout reflects the 4x4’s pickup-based design carried over from the Hilux utility lineage.

Why no gas struts? The Surf’s tailgate drops like a ute, with cable/hinge support and a powered glass that winds down into the gate. That means there’s nothing overhead at the rear needing assistance to hold itself up. Up front, Toyota opted for a robust rod to hold the bonnet—cost-effective, dead reliable in corrugations and mud, and easy to service in the bush. It’s a very late-’80s Toyota approach: fewer moving parts, fewer headaches.

Owners sometimes encounter gas struts on these trucks, but that’s typically from aftermarket add-ons—think a canopy or rear window conversion on a Surf-imported shell, a bonnet strut retrofit kit, or accessories like a swing-away carrier with a damper. Those aren’t OE for the 1989 Surf.

If the vehicle has aftermarket gas struts fitted, a few maintenance tips keep things tidy:

• Replace in pairs when one weakens, mismatched force can twist mounts.
• Watch for tell-tales: slow lift, needing a hand to hold, oily film on the shaft, or a “thud” as it drops in the cold.
• Keep the chrome shafts clean, don’t grease them—oils attract grit and chew out the seals.
• Match length, end fittings, and Newton rating to the brackets and panel weight, stainless bodies are worth it for coastal use.
• Support the panel safely during replacement—never trust a tired strut over your head.

For bonnet strut conversions, quality brackets that spread the load are crucial. Avoid drilling into thin inner skins without reinforcement. In Australia and New Zealand, ensure any modification doesn’t interfere with bonnet latches or ADR/WoF safety expectations.

FAQs

Does a 1989 Toyota Hilux Surf have factory gas struts?
No. Factory documents show a bonnet prop rod and a drop-down tailgate with a power rear window. There’s no OE gas stay for the bonnet or rear because the vehicle doesn’t have a liftback hatch.

Can gas struts be retrofitted to the bonnet or rear?
Yes, bonnet strut kits exist, and some canopies or custom rear glass frames use gas stays. Use well-engineered brackets, confirm load ratings, and ensure the bonnet closes and latches correctly. If unsure, have a professional fitter handle it.

How can someone tell if aftermarket gas struts need replacing?
If panels won’t stay up, rise sluggishly, or drop faster in cold weather, the struts are on the way out. Any oil film on the shaft is a seal leak. Replace as a pair with the correct length and force to protect mounts and hinges.
