Coilover Spring 6in x 2.5in ID

The Coilover Spring 6in x 2.5in ID from EIBACH is a precision-engineered suspension component designed for builders and enthusiasts who demand repeatability and performance in their vehicle dynamics. This coilover spring serves as the foundation for modern suspension tuning, replacing factory springs in custom setups where adjustable ride height, stiffness customization, and corner-weight balancing are essential. Whether you're building a track car, lowering a street machine, or dialing in a dedicated drift platform, this EIBACH unit delivers the consistency required to achieve target spring rates and vehicle geometry.

Built to exacting tolerances, the 6-inch free length and 2.5-inch inner diameter of this coilover spring integrate seamlessly with aftermarket coilover kits and custom suspension packages commonly found in performance applications. EIBACH springs are manufactured using high-tensile steel wire and precisely wound to maintain load consistency across the entire stroke range, critical when tuning anti-roll characteristics and preventing chassis binding during aggressive cornering. The 2.5-inch ID allows compatibility with standard monotube and twin-tube damper bodies, making this spring a versatile choice for both amateur tuners and professional fabricators building one-off suspension systems or preparing competition vehicles.

This coilover spring suits builders working with universal coilover kits, custom strut housings, or standalone damper platforms where spring selection directly impacts suspension geometry and vehicle handling. Mechanics and fabricators typically pair these springs with adjustable coilover bodies to achieve desired ride heights and spring rates for specific weight classes and driving conditions. Always verify compatibility with your chosen coilover housing or damper before installation, and match spring rates (not included in the spring alone) to your vehicle's total weight and suspension design to ensure balanced front-to-rear load distribution and predictable on-road or track behavior.
