Car Boot struts

Boot struts, also known as tailgate dampers or boot lift supports, are vital car components specifically designed to support the trunk lids. These clever actuators convert stored energy into controlled mechanical motion, ensuring your boot opens safely and effortlessly.

They operate using pressurised nitrogen, sealed within a cylinder. When the boot is opened, this gas expands, pushing a piston and rod outwards. This creates a smooth linear motion, applying the force needed to lift and securely hold the lid against gravity. Such precise, controlled movement greatly enhances user comfort and safety, and integrates with the vehicle's overall access systems, including car keys and central locks.

What types of boot struts are available?

Boot struts are primarily available in two forms: conventional gas-pressurised units, which assist you in manually opening and closing the boot, and 'power tailgate' models, which are electric and manage the boot's operation automatically.

For a perfect fit and optimal performance, both types must precisely match your vehicle's make, model, and year. Furthermore, these supports are often side-specific, typically marked as 'Left' or 'Right' Tailgate Damper. For the best performance, they are sometimes sold as a pair.

What causes Boot Strut Failure?

Boot strut failure is often caused by a combination of component degradation and harsh environmental conditions. The primary reasons for malfunction include:

  • seal degradation, which allows internal gas to escape and significantly reduces the strut's lifting power,

  • corrosion on the steel shaft, generating friction that damages seals and accelerates overall wear,

  • external contaminants such as dust, dirt, and moisture compromising the seals, with water infiltration exacerbating leaks,

  • physical damage to the strut's body or shaft impeding its movement and potentially leading to complete operational failure,

  • operating the strut beyond its intended duty cycle, causing premature wear and malfunction,

  • exposure to extreme temperatures, leading to premature wear and malfunction.

What symptoms indicate worn or failing boot struts?

Faulty boot struts quickly make themselves known, affecting the comfort and safety of vehicle use. The most common symptoms of their wear include:

  • the boot lid does not stay open,iIt either falls back down or struggles to remain in the raised position, often also affecting the proper function of trunk lid latches

  • slow or abrupt closing,

  • the boot feels significantly heavier, which indicates a loss of lifting force,

  • the movement of the lid becomes jerky and loses its smoothness,

  • in the event of complete failure, the strut stops offering any support at all,forcing you to manually lift and hold the lid open.

How long do boot struts last?

The lifespan of boot lid struts varies considerably, influenced by several key factors:

  • how frequently the boot is opened and closed,

  • environmental conditions, such as extreme temperatures, high humidity, or salt exposure,

  • the inevitable wear of internal components over time, leading to reduced pressure and performance,

  • the quality of the strut itself, with well-made options offering greater longevity,

  • the overall intensity of use and exposure to harsh weather.

Should you replace boot struts in pairs?

Yes, you should always replace them as a pair. Boot struts endure similar wear and tear due to their shared age and exposure to the elements. For optimal performance and longevity, replacing only one strut can lead to several problems:

  • uneven load distribution, which overstresses the new component, its mounting points, and the trunk hinges,

  • an imbalance that causes misalignment and can lead to the premature failure of parts.

Conversely, replacing both struts ensures balanced performance and offers significant benefits:

  • guaranteed balanced performance and restored original safety features,

  • greater cost-effectiveness in the long run, by avoiding the hassle and expense of a subsequent repair.

How to match boot strut spring force and length to your vehicle?

It's crucial to replace boot struts in pairs for balanced performance and safety. Selecting the correct replacements is essential; the strut's force and physical dimensions must perfectly align with your car's original components for proper operation.

The force, typically measured in Newtons (N) or lbf, must adequately support the boot lid's weight. Equally important is the stroke length; both its extended and compressed lengths should precisely match the old unit.

Begin by finding the OEM part number. This unique identifier, specific to your vehicle, will guide you to compatible replacements. Always verify other crucial details: pay close attention to the load capacity, stroke length, and mounting bracket types. For example, some struts use clevis fittings while others feature pivot points. Checking these details guarantees a perfect fit and ensures optimal operation is restored.
