Coilover Spring 12in x 2.5in x 375lb

The Coilover Spring 12in x 2.5in x 375lb by SWIFT SPRINGS is a premium performance suspension component designed for vehicles that require precise vertical load control and damping response. This product is ideal for automotive enthusiasts and mechanics who seek repeatability in handling characteristics, making it suitable for street performance, track day vehicles, and builds with adjustable dampers.

Engineered with a spring rate of 375 pounds per inch (lbs/in), this coilover spring balances compliance and stiffness, ensuring consistent ride height and cornering geometry across various driving conditions. The 12-inch free length and 2.5-inch inner diameter allow compatibility with standard coilover shock bodies, facilitating broad ride height adjustments without coil binding or excessive preload. Crafted from high-carbon alloy steel and heat-treated, this spring maintains consistent load characteristics through numerous compression cycles.

Drivers building or upgrading independent double-wishbone or MacPherson strut suspension systems will benefit from the predictable suspension behavior provided by this linear spring rate. When paired with quality dampers, it optimizes weight transfer and tire contact during acceleration, braking, and cornering, enhancing overall vehicle performance.
