Parts for your 2020 Ford Fiesta-Gas struts

2020 Ford Fiesta gas struts — what they do and when to replace

Based on technical sources — Ford Workshop Manual for the 2018–2020 Fiesta (Mk8) Section 501‑03 Body Closures (Liftgate), Ford Electronic Parts Catalogue listings for rear liftgate gas springs, and OEM supplier catalogues (e.g., Stabilus, Monroe) — the 2020 Ford Fiesta hatch is fitted with twin gas struts on the rear liftgate/boot. The bonnet on this model uses a manual prop rod and is not equipped with gas struts.

On the Fiesta, the boot gas struts take the weight of the tailgate, helping it lift smoothly and stay put without slamming down. They’re sealed, nitrogen-charged dampers designed to work across a range of temperatures and make everyday use feel light and easy.

There’s no fixed service interval for gas struts, but they’re wear items. Over time, seals can weep and internal pressure drops, especially after years of heat cycles and dust. Replacing them when they get lazy keeps the boot safe and convenient — a must if there are kids, groceries, or tools constantly going in and out.

Typical signs it’s time to replace the Fiesta’s boot struts:

• Boot doesn’t lift by itself or needs a big shove, especially on cold mornings
• Tailgate won’t stay up or sags lower than usual
• Greasy film or oil weep on the strut body
• Clicking, binding or uneven movement

Replacement is a quick driveway job for most owners. Always support the tailgate with a prop or a mate before popping off the clips. Struts are usually replaced in pairs to keep lift and balance even. Don’t lubricate the shiny piston rod — that can damage the seals. After fitting, open and close the boot a few times so the end fittings settle on their ball studs. If the Fiesta has a larger spoiler (as on some ST models), make sure the new struts match the specified force rating for that variant.

Workshop pointers:

1. Record the concern on a service sheet (slow lift, won’t hold, visible leak)
2. Inspect hinge play, ball studs and clip condition while you’re there
3. Use quality, correctly rated struts, avoid mixing brands or ratings

Done right, fresh gas struts make the Fiesta’s boot feel new again, keeping day‑to‑day use safe, tidy and hassle‑free.

How long do the Fiesta’s boot gas struts usually last?

It varies with climate and use, but many owners see 5–10 years or around 80,000–150,000 km before performance noticeably drops. If the car lives outdoors in hot or coastal conditions, expect the lower end of that range. Replace at the first sign of sagging or leaking — there’s no benefit in waiting.

Should they be replaced in pairs?

Yes. Pair replacement keeps lift force even and prevents twisting the tailgate. Swapping just one can leave the boot unbalanced, harder to lift, and more likely to drop unexpectedly.

Can the Fiesta’s bonnet be upgraded to gas struts?

The 2020 model uses a prop rod from factory. Aftermarket bonnet strut kits exist, but only fit if designed for the Mk8 Fiesta and the mounting points provided. Check load ratings and hardware quality, and note that non-genuine mods may affect warranty or insurance if they fail.
