Tailgate Torsion Spring: Durable Support for Trunk & Hatch Operations
Seamless functionality and reliable performance are essential for any vehicle’s tailgate or hatch mechanism. At the core of this system is the Tailgate Torsion Spring, a precision-engineered component that provides smooth opening, secure holding, and controlled closing. When you need strong, long-lasting support for liftgates, hatchbacks, or SUV trunks, consider a professional-grade Tailgate Torsion Spring from Chengfa Springs — the trusted choice for automotive OEMs and aftermarket applications.
What Is a Tailgate Torsion Spring?
A tailgate torsion spring is a coiled spring mounted along the tailgate shaft. It stores mechanical energy to:
- Assist Opening: Counterbalances the weight of the tailgate for smooth lift operations.
- Hold Position: Keeps the tailgate open firmly, preventing unintentional closure.
- Control Closing: Applies a measured resistive force during closing to avoid slamming.
Benefits of High-Quality Tailgate Torsion Springs
- Enhanced Safety: Prevents sudden drops to protect users.
- Driver Convenience: Minimal effort needed to lift and close the tailgate.
- Long Service Life: High fatigue resistance for thousands of open/close cycles.
- Weather Resistance: Designed to withstand moisture, heat, and corrosion.
Common Applications
Tailgate torsion springs are widely used in:
- SUV and crossover rear liftgates
- Hatchbacks and wagons
- Van and utility vehicle rear doors
- Aftermarket lift-assist kits
- Camper and recreational vehicle access hatches
