Construction & Design

ST Suspensions Adjustable Lowering Springs are crafted from high-strength chrome silicon steel, a material known for its excellent fatigue resistance and durability. The springs undergo a cold winding process followed by multi-tempering treatments to ensure consistent spring rates and long service life. A final epoxy coating protects against corrosion and environmental wear, making these springs suitable for various weather conditions.

This innovative approach effectively converts your stock suspension into a height-adjustable setup, delivering the benefits of coilovers without the complexity or cost.
