The use of professional spray paint coating, bright color, not easy to fall off the paint effectively prevent spring oxidation.

 

Product Installation

1. High-Stress Shot Peening Process
To significantly enhance the fatigue life of the spring, every unit undergoes a shot peening process. This creates compressive residual stress on the surface, preventing the formation of micro-cracks and ensuring the spring can withstand millions of compression cycles without sagging.

2. Advanced Heat Treatment (Quenching & Tempering)
We utilize continuous atmosphere-controlled furnaces for heat treatment. This ensures the spring steel achieves a perfect balance between hardness and elasticity, preventing the spring from being too brittle (leading to breakage) or too soft (leading to loss of ride height).

3. Superior Corrosion Resistance
Understanding that Hilux trucks often operate in humid or salty coastal environments, our springs are treated with a multi-layer anti-corrosion coating. This exceeds 240 hours of salt spray testing, ensuring the product remains aesthetically clean and structurally sound for years.

4. Pre-Setting & Load Testing
Every spring is "solid height" tested or "pre-set" to its limit during production. This eliminates initial "settling" after installation, ensuring that when your customer installs the spring, the vehicle's alignment remains perfect from day one.
