Spring 10in Coil-Over 3.0in ID Silver

The Eibach Spring 10in Coil-Over 3.0in ID Silver is a precision-engineered suspension component built for serious vehicle builders and performance enthusiasts who demand tunable ride quality and consistent spring rates across varied driving conditions. This 10-inch coil-over spring is the backbone of independent suspension tuning, allowing you to dial in exact ride height, load capacity, and natural frequency for everything from road racing to autocross setups. Eibach's reputation in the performance suspension industry makes this spring an ideal choice for chassis builders who refuse to compromise on predictability and longevity.

At 3.0 inches inner diameter, this coil-over spring integrates seamlessly with standard monotube and twin-tube dampers, providing a robust mechanical interface that handles the full range of suspension articulation without binding or noise. The silver finish provides corrosion resistance critical for long-term durability in wet climates, while the 10-inch free length gives you adequate compression and extension ranges for both comfort-oriented and track-focused applications. Eibach's manufacturing process ensures consistent wire diameter and coil pitch, which translates to linear spring rate behavior—a necessity when you're fine-tuning suspension geometry or testing different shock valving configurations.

This spring delivers real value for independent suspension builds on street cars, race cars, and off-road platforms where OEM springs lack the adjustability needed for custom geometry or weight distribution changes. Mechanics and fabricators frequently pair 10-inch coil-overs with adjustable dampers to achieve full suspension tunability, making this component essential when you're upgrading to air suspension, hydraulic lowering systems, or performance-oriented double-wishbone conversions. Before installation, verify your damper specifications match the 3.0-inch bore diameter, and confirm free length compatibility with your chosen shock mounting points to ensure optimal ride height and suspension travel.
