1 7/8in ID Spring 300# 10in Tall

The 1 7/8in ID Spring 300# 10in Tall by HYPERCO is purpose-built for serious suspension tuning and vehicle modifications where precise spring rate control matters. Whether you're building a high-performance street machine, designing a track-focused suspension geometry, or engineering a custom hot rod platform, this coil spring delivers the consistency and durability professional mechanics and fabricators demand. HYPERCO springs are engineered to exacting standards, making this component ideal for builders who refuse compromises on ride quality, handling response, or long-term reliability.

With a 300-pound spring rate and 10-inch compressed height, this spring delivers linear load response across its travel range—critical for suspension systems requiring predictable damping behavior and consistent weight transfer during cornering, acceleration, and braking. The 1 7/8-inch inside diameter (ID) accommodates standard monotube and twin-tube shock absorber designs, ensuring seamless integration into proven suspension architectures. HYPERCO's manufacturing process maintains tight tolerances on rate consistency, preventing the spring pack variation that plagues inferior coils and guarantees identical handling left-to-right across your vehicle's axles.

This spring suits independent double-A-arm, MacPherson strut, and multi-link suspension designs common in street rods, race cars, and heavily modified daily drivers. Applications range from vintage hot rods receiving modern suspension overhauls to contemporary platforms undergoing aftermarket chassis upgrades. At 3.2 lbs per spring, verify your complete spring package weight matches your vehicle's intended handling balance and load distribution geometry before installation, and always pair springs with matched dampers tuned to your specific 300# rate for optimal suspension performance.
