Hands-Free Trunk Opening Made Effortless
Upgrade your vehicle's manual trunk to an automatic lifting system in minutes. Crafted from high-carbon alloy steel for reliable, everyday convenience.
Effortless Hands-Free Access
No more struggling to manually lift your trunk when your hands are full of groceries or luggage. Simply press your trunk release button, and the high-tension spring assists in smoothly lifting the lid automatically.
Built to Last with Alloy Steel
Manufactured from robust high-carbon alloy steel, this spring guarantees excellent resistance to rust, corrosion, and deformation. It is heavily engineered to withstand thousands of opening and closing cycles without losing tension.
Customizable Lifting Power
Features a full-thread screw mechanism that lets you perfectly adjust the tension. Match the spring's strength precisely to your car’s trunk weight to ensure a smooth, controlled opening every single time.
Install in Minutes
Skip the expensive mechanic visits. The spring hooks directly onto your existing trunk brackets. Adjust the length to fit, secure it with the included anti-break clips, and enjoy your new automatic trunk.

Frequently Asked Questions
Common questions about compatibility and installation.
Will this fit my specific car model?
This spring is designed as a universal fit for most standard sedans that use traditional trunk hinge systems. Please note it is not compatible with hatchbacks, SUVs, minivans, or any vehicle that already uses hydraulic struts.
How do I adjust the lifting speed?
You can easily control the lifting speed by adjusting the built-in screw threads. Lengthening or shortening the spring via the screw changes the tension, allowing you to find the perfect, gentle opening speed.
Will the spring break or stretch out over time?
No. It is crafted from high-carbon alloy steel and features an anti-break conical limiting device. This ensures the spring maintains its shape and tension even after long-term daily wear and tear.
