Parts for your 2013 Ford Territory-Gas struts

2013 Ford Territory gas struts: purpose, care and replacement

Yes, gas struts are absolutely used on the 2013 Ford Territory (SZ series). Technical sources including the Ford Territory SZ Workshop Manual (Section 501-03: Body Closures and Security), the Ford/Microcat AU parts catalogue (listings for “strut—back door” and “strut—bonnet”), and common fitment guides from brands such as Stabilus Lift-O-Mat and Monroe Max-Lift all specify gas-charged support struts for both the tailgate and the bonnet on this model.

On a 2013 Territory, the gas struts do the heavy lifting: they counterbalance the weight of the tailgate and bonnet so they open smoothly and stay up safely. When they’re healthy, the tailgate glides open without a shove and the bonnet stays put without a prop. When they’re tired, you’ll notice the door sagging, slow or jerky movement, or the need to shoulder-lift it—especially on a cold morning.

There’s no fixed service interval for gas struts, they’re replaced on condition. As part of routine servicing, it’s smart to check for these signs:

• Tailgate or bonnet won’t hold at full height, or drops unexpectedly
• Noticeable slow rise, sticking, or needing a helping hand
• Oil mist or dirt build-up on the rod/seal area
• Clicking at the ball sockets or loose mounting hardware

If replacement’s due, always do them in pairs per axle (both tailgate struts together, or both bonnet struts together) to keep lift and balance even. Supporting the door with a prop or helper is a must. Swapping them is generally straightforward—prise the spring clip or remove the retaining fastener, pop the old strut off the ball stud, then click the new one on. Refit any clips and tighten hardware to manufacturer spec. Avoid twisting the body, don’t clamp the chrome rod, and never puncture or heat a gas strut.

For longevity, keep the rod clean (mild soapy water only), don’t grease the rod (it can damage the seals), and check the ball studs for wear. Expect lifespan to vary with use and climate, temperature affects gas pressure, so weak struts often show up first in winter. Quality OE-equivalent parts from recognised suppliers (as listed in the above fitment guides) will restore that factory lift and hold on the Territory’s tailgate and bonnet.

Popular questions about 2013 Ford Territory gas struts

How long do the gas struts usually last on a Territory?
Most owners see 5–10 years depending on climate, use, and how often the tailgate/bonnet is operated. Cold weather and frequent loading can bring on symptoms sooner. Replace when they no longer hold or lift cleanly.

Can gas struts be re-gassed or should they just be replaced?
For the Territory, replacement with new, correct-rate struts is the recommended fix. Re-gassing or DIY topping up isn’t generally supported by OEM or major aftermarket providers and can be inconsistent or unsafe.

Do both struts need to be changed at the same time?
Yes—replace them in pairs on the tailgate or bonnet. Mixing an old and a new strut can lead to uneven lift, extra stress on hinges and mounts, and reduced service life.
