Tailgate Gas Spring for Vehicle Rear Doors — Precision Lift Support with OEM-Grade Reliability
The Tailgate Gas Spring is a hydropneumatic motion control part that provides a constant and regulated force for raising and balancing car rear doors. For smooth and quiet operation, it is made up of nitrogen-filled cylinders, precise piston rods, and high-performance seals. Xingtai Juxiang Machinery Manufacturing Factory was established in 2002 and has been in production for more than 20 years. Professional technical and management personnel make up our 100-person team. Every product complies with ISO 9001 and IATF 16949 standards, operates steadily between -40°C and +80°C, and has a 50-unit minimum order quantity (MOQ) for large orders.
What Makes Our Tailgate Gas Spring Different?
Because our tailgate gas spring is made in accordance with normal OEM requirements, it may be replaced directly without modification or additional tools. In order to increase corrosion resistance and lower surface friction, the piston rod uses seamless steel tube with QPQ surface treatment. This effectively slows internal seal wear and prolongs service life.
There is no daily maintenance needed for the built-in self-lubricating structure. Each unit, which is filled with fixed-volume damping oil and inert nitrogen gas, creates end-position buffering and steady linear force, reducing mechanical shock to the vehicle's hinges and chassis.

Core Performance Advantages
Every cycle has silent soft-closing thanks to the nitrogen/hydraulic system. There is just steady, controlled motion—no rattling, no abrupt drop, and no startling pop-up.
Both abrupt closure and uncontrollable extension are prevented by built-in dampening. Over thousands of cycles, this lessens the mechanical stress on the vehicle's hinge points and shields the operator from harm.
Reliable operation in wet, snowy, and salty conditions is made possible by the corrosion-proof surface treatment. The sealing performance is constant whether your cars are driven in dusty industrial areas, coastal regions, or cold climates.
Additionally, we advise changing both sides at the same time. Uneven support from mismatched units diminishes overall stability and speeds up wear on the stronger side, equal if only one strut exhibits weakness.
Quality Control & Testing Standards
Every product undergoes extensive testing before to delivery. With 144 to 500 hours of testing, salt spray testing satisfies ASTM B117 criteria. Cycle durability testing verifies constant force and sealing performance after over 50,000 cycles. Force levels are controlled between ±5% and ±10% to guaranty dependable tailgate operation.
Extreme temperature testing stabilizes internal gas pressure and oil viscosity for different regional climates. Piston rod surface testing keeps smooth finish to reduce seal abrasion.
Applications Across Industries
Tailgate gas springs are widely used in multiple scenarios. They fit SUVs, hatchbacks and electric vehicles for consistent daily use, and support heavy tailgates of ambulances and engineering vehicles to reduce operating load. Optimized sealed structures adapt to coastal salt spray environments. Our gas spring series also applies to medical devices, mechanical equipment, furniture and rail transit facilities.
Customization & B2B Supply Support
For both passenger and commercial vehicle types, we provide complete OEM/ODM customisation for stroke length, force value, connections, branding, and packaging. Trial purchases and bulk manufacturing are supported by the 50-unit MOQ. With full certification and logistical documentation, we provide full foreign trade services, exporting to Europe, Russia, South America, the Middle East, Southeast Asia, and Africa.
FAQ
Q1: In cold temperatures, why do gas springs lose force?
A: Nitrogen pressure decreases at low temperatures. In low-temperature settings, optimal damping oil viscosity reduces force variation.
Q2: How should an installation be done?
A: To ensure steady damping and lubricate seals, install with the piston rod pointing down.
Q3: What leads to oil leaks in gas springs?
A: Seal failure is caused by chemical corrosion, long-term cycle wear, or scratches on the rod surface. Such dangers are significantly reduced by QPQ therapy.
Q4: How to confirm the correct replacement force?
A: Check the Newton mark on the cylinder surface, or calculate parameters based on tailgate weight and hinge distance.
Q5: Do you support small trial orders?
A: Yes. 50-unit MOQ supports sample testing and small-batch procurement for buyer evaluation.
