Parts for your 2015 Toyota Hilux-Gas struts

2015 Toyota Hilux gas struts — relevance, purpose and care

Based on Toyota’s 2015 Hilux owner’s manual and parts catalogue, plus Toyota Genuine Accessories fitting guides, the factory 2015 Hilux uses a bonnet prop rod and cable-supported tailgate, not gas struts. Gas struts are, however, commonly used on Toyota Genuine and aftermarket accessories for this model — think canopy rear and side glass, hard-lid tonneaus and tailgate-assist kits. That makes “gas struts” relevant to a 2015 Hilux only when those accessories are fitted.

Why didn’t Toyota fit them from new? Simplicity, cost, and durability off-road. A steel prop and cables are rugged, cheap to service in the bush, and don’t lose pressure over time. For owners who add a canopy or hard lid, gas struts are the right tool for the job — they safely lift and hold heavier panels without a second pair of hands.

If the Hilux has gas struts fitted, they’re there to do two things: make lifting easier and hold panels up securely. On a canopy or hard lid, the struts counterbalance the panel’s weight, so it opens smoothly and stays put, even in a breeze. Tailgate-assist kits use a strut to slow the drop and reduce strain on hinges and cables. Over time, seals wear and nitrogen charge bleeds off, so their lift fades — that’s normal, and it’s the cue to replace them.

• Service check: At regular services, open the panel and confirm it lifts smoothly and stays up. Any sagging, jerky motion, oil mist on the shaft, or a need to “help it” open means the struts are tired.
• Replace in pairs: Always swap both sides together to keep even lift and avoid twisting hinges or glass. Match length, end fittings and force rating (in newtons) to the canopy or lid maker’s spec.
• Fitment tips: Support the panel with a prop, keep hands clear, and orient most struts rod-down so oil keeps the top seal lubricated. Don’t clamp the shaft with pliers and don’t grease it — just wipe clean with a lint-free, silicone-free cloth.
• Hardware check: Inspect ball-studs, brackets and rivets for looseness or corrosion
