Crafted from premium high tensile chromium-silicone wire, these springs are engineered for durability and consistent performance.

The phosphate treatment and powder coating provide superior corrosion resistance, ensuring longevity beyond the vehicle's lifespan. Featuring progressive spring rates, these springs offer a balanced ride quality, combining comfort with enhanced stability during spirited driving or cornering.

These springs are ideal for daily drivers, street performance, and enthusiasts aiming for a lowered, aggressive stance.
