1 7/8in ID Spring 375# 10in Tall

The HYPERCO 1 7/8in ID Spring 375# 10in Tall (SKU HYP1810D0375) is a high-performance coil-over suspension spring engineered for vehicles requiring precise spring rate control and consistent damping characteristics. With a 1.875-inch inner diameter, 375 lb/in spring rate, and 10-inch compressed length, this steel spring delivers the stiffness needed for performance suspension tuning on track vehicles, off-road platforms, and competition rigs where suspension geometry demands exact spring specifications.

The 375-pound-per-inch rate places this spring in the mid-range stiffness category, suitable for vehicles with moderate to aggressive suspension setups. The 10-inch length accommodates most coil-over shock assemblies without excessive binding or extension issues. Blue powder-coat finish provides corrosion resistance for long-term durability in varied climates, whether exposed to track salt spray or off-road moisture. At 3.15 pounds, the spring weight is consistent with quality performance springs and does not introduce unnecessary unsprung mass to the suspension system.

This spring suits builders and enthusiasts upgrading coil-over suspension kits, lowering systems, or custom chassis applications where OEM springs fall short of performance requirements. Buyers integrating this spring should verify compatibility with their shock body diameter, total suspension travel, and ride-height targets to ensure proper fitment. The HYPERCO 1 7/8in ID Spring is sold individually, allowing builders to purchase matched pairs or sets as needed for their specific platform.

HYPERCO springs are manufactured to tight tolerances, making them a go-to choice for serious suspension work where spring rate consistency directly impacts handling balance and vehicle control.
