Six product lines.
One source factory.

MOQ depends on the product line. For standard catalog gas springs and lift supports, the MOQ is typically 50–100 units per model. For custom-engineered products (force curve, mounting, surface), MOQ is negotiated case by case — usually 200+ units. Contact us with your specific model and we'll confirm quickly.

Yes. We supply to automotive distributors, aftermarket brands, and online sellers who sell under their own label. We can print your brand name, logo, and part numbers on the product and packaging. Our standard practice is to treat OEM partnerships with full discretion — we do not cross-supply competitors within the same market region.

Absolutely. Send us the vehicle model, the target lift angle, door weight, and mounting points. Our engineering team will calculate the required extended force, compressed force, and optimal stroke length. We offer free technical consultation and produce samples within 15–25 business days. Tooling costs apply for custom end fittings.

All products are 100% bench-tested before shipment — force output is measured and must fall within ±5 N of spec. Batch samples undergo:

• 50,000-cycle fatigue test
• 500-hour salt-spray corrosion test (per ISO 9227)
• Temperature cycling from -40 °C to +80 °C
• Gas retention test (zero leakage after 72-hour hold)

For in-stock standard catalog items, we can ship within 3–7 business days. For production orders, lead time is 15–30 days depending on quantity. We ship by sea (FCL/LCL), air freight, or express courier (DHL/FedEx/UPS). We can ship EXW, FOB Guangzhou, or CIF — your choice.

We warrant our products to be free from material and manufacturing defects for 12 months from the date of shipment (or 18 months for OEM supply contracts). Failed units should be returned with the batch number visible. We will inspect and, where a manufacturing defect is confirmed, replace the units at no cost including outbound freight.

We maintain warehouse stock of our top 80 best-selling fitments (mainly Mercedes-Benz, BMW, Audi, Toyota, and Hyundai/Kia platforms). All other catalog items are built on order. Send us your inquiry and we'll confirm stock availability within 4 hours during business hours (GMT+8).

A gas spring (also called a lift support or gas strut) is a sealed nitrogen-filled rod used to hold a hood, trunk, or tailgate open. It provides a fixed push force. An air spring is a rubber bellow filled with compressed air used in a vehicle's suspension system — it replaces a coil spring and allows ride-height adjustment. We manufacture both, along with electric actuators, hydraulic dampers, and rubber buffers.
