Coilover Spring 1.875in ID 10in Tall 140lb

The Coilover Spring 1.875in ID 10in Tall 140lb from DRACO RACING is engineered for builders seeking precision suspension tuning on custom and modified vehicles. This replacement spring delivers consistent rate and preload characteristics essential for street, drift, and track applications where OEM suspension geometry has been altered. Whether you're lowering a chassis, adjusting ride height for aerodynamic efficiency, or fine-tuning handling balance, this coilover spring provides the foundation for repeatable, predictable suspension performance without compromise.

Built with a 1.875-inch inner diameter and standing 10 inches tall, this spring accommodates standard coilover shock mounting systems and delivers a 140-pound spring rate—a mid-range specification ideal for street-driven modified vehicles balancing comfort with responsive handling. The tight tolerance machining ensures consistent load distribution and eliminates bind points that compromise suspension articulation. At 1.73 pounds, the spring weight contributes minimal unsprung mass, supporting faster suspension compliance and improved tire contact patch consistency over imperfect surfaces.

This coilover spring suits builders upgrading independent coilover suspension kits, adjustable shock absorber platforms, and custom fabricated chassis setups on street cars, drift platforms, and weekend track machines. Verify your shock body's inner diameter and available spring seat clearance before ordering; 1.875-inch ID is common across major coilover manufacturers but confirmation prevents costly installation errors. Pair with compatible dampers rated for 140-pound spring rates to achieve intended suspension kinematics and component longevity.
