14in C/O Spring Platinum 2.50in ID

The Eibach 14in C/O Spring Platinum 2.50in ID is a premium coil-over spring engineered for serious automotive suspension builders and track-focused enthusiasts who demand precision tuning. This 14-inch barrel-style coil spring serves as the foundation for custom suspension geometry, allowing you to dial in ride height, spring rate, and chassis balance independently from your damper selection. Whether you're building a road-racing platform, autocross competitor, or street-performance vehicle, this Platinum Series spring delivers the consistency and durability required for demanding applications.

Manufactured from high-quality steel and finished with Eibach's proprietary Platinum powder coat for superior corrosion resistance, the 14in C/O Spring Platinum 2.50in ID features a 225 lb/in spring rate that provides responsive load control without excessive harshness. The 2.5-inch inner diameter (ID) is a universal coil-over standard, ensuring compatibility with most aftermarket damper bodies and allowing seamless integration into existing or new suspension designs. The 14-inch length and barrel geometry minimize binding while optimizing the natural frequency response critical for performance driving, making this spring ideal for applications requiring precise suspension tuning without compromise.

Professional mechanics, suspension shops, and dedicated tuners choose the Eibach Platinum Series for reliability under extreme conditions—track days, competition, and aggressive street use where spring fatigue or inconsistency is not an option. The 225 lb/in rate strikes a balance suitable for lightweight to mid-weight vehicles, delivering sufficient support for cornering loads while maintaining driver feedback and ride quality. Installation pairs with quality dampers and proper setup geometry; correct preload adjustment and ride-height configuration ensure optimal performance. At 5.4 lbs per spring, account for a complete four-corner set in your suspension weight calculations for precision vehicle setup.
