Automotive Sliding Door Gas Strut with Dampening
Engineered for linear motion control, Land gas springs (gas struts / gas shocks) use compressed nitrogen and oil damping to balance door weight, prevent slam, and improve ergonomics. Precision-rolled cylinders, heat-treated rods, and leak-proof seals deliver consistent force over millions of cycles. Choose standard compression springs for assisted lift, hydraulic dampers for soft-close, or inter-stop/locking types for position holding.
Key Features
- Sized for Sliding Doors: common strokes 4–16 in (100–400 mm); forces 80–1200 N (18–270 lb).
- Smooth & Quiet: integrated oil damping reduces bounce and door shock.
- Durable Build: 20-year factory experience, 5-year warranty, free replacement policy.
- Finish Options: black nitrided steel, stainless steel 304/316 for coastal or hygienic areas.
- End Fittings: ball sockets, eyelets, clevis, brackets for fast retrofit.
- Custom Tuning: we set force to your door weight and mounting geometry; 3D CAD in 24 h.
- Safety Choices: inter-stop (position hold), mechanical locking, or soft-close dampers.
Our innovative end-position damping system
- Gently arrests door motion when forcefully opened
- Maintains position during strong winds or on inclines
- Remains nearly imperceptible during normal operation
- Progressively increases resistance with movement speed
Key Advantages for Automakers
- Maintenance-free, self-lubricating operation
- Seamless integration with power closure systems
- Customizable force profiles for brand-specific haptics
- Enhanced perceived quality through controlled motion
