The Spring Conventional 8.00in x 5in x 425lb from SWIFT SPRINGS is a precision coil spring designed for performance suspension tuning and custom vehicle builds. This spring is ideal for lowering street cars, fine-tuning track setups, or restoring classic vehicles with modern handling characteristics.
Engineered with a spring rate of 425 pounds per inch (lb/in), it balances ride comfort with adequate support for moderate performance applications. Made from high-carbon spring steel and heat-treated for durability, this conventional spring maintains a consistent rate across its full compression range and resists fatigue over thousands of cycles.
This spring is particularly beneficial for front or rear suspension upgrades on street-performance vehicles, road-course builds, and vintage restorations that require modern geometry. To achieve optimal handling, it should be paired with quality dampers and proper ride-height geometry.
