We are a direct source factory specializing in coil springs, covering both OEM replacement and 4×4 off-road aftermarket suspension applications. Customization is fully available to match your unique project requirements.
Whether you need coil springs made strictly to OEM original specifications for vehicle factory replacement, or performance upgrade springs built for tough off-road modification, we can tailor the product according to your drawings, load data, stiffness, dimensions and technical standards.
Multiple surface protection options are optional for your selection, including E-coat protection, zinc plating, Dacromet and more. Our E-coat protection delivers uniform coverage even inside spring coils, great adhesion and reliable anti-corrosion performance, complying with RoHS and REACH for export.
We control production performance strictly. We stabilize spring force consistency, adopt pre-set squash and roast process to reduce permanent set and load loss, and optional shot peening improves fatigue life for heavy-duty off-road use. Strict QC testing such as salt spray, fatigue and load curve inspection is available.
Flexible packaging solutions are supported. Choose individually packed springs, divider boards inside cartons or custom packaging with your branded side marks. Our packing design is optimized for long ocean shipping to prevent tangling, scratching and rust.
If you are sourcing coil springs for OEM projects or off-road suspension upgrades, send us your specifications today. We provide one-stop custom spring solutions to help you avoid quality and export risks.
