Spring 18in Coil-Over 2.5in ID Silver

The Spring 18in Coil-Over 2.5in ID Silver from Eibach is a precision coil spring engineered for coil-over suspension systems where fine-tuned ride height and spring rate control are critical. Built for custom suspension builders, performance enthusiasts, and professional installers, this coil-over spring delivers consistent load support and predictable handling characteristics across a wide range of applications. The 18-inch length and 2.5-inch inner diameter make this spring compatible with most modern coil-over kits designed for street performance, road racing, and off-road platforms.

This coil-over spring features a 175 lb/in spring rate, calibrated to provide balanced compression stiffness without excessive harshness during normal driving or track use. Constructed from high-quality steel and finished with silver powder coating, the spring resists corrosion and maintains structural integrity even in harsh weather or salt-exposure environments. The precision winding and consistent coil geometry ensure even load distribution, minimizing spring sag over time and maintaining accurate suspension geometry for optimal tire contact and vehicle stability.

This spring is ideal for automotive enthusiasts building custom coil-over suspension systems on performance vehicles, track cars, and modified street platforms. The 175 lb/in rate works well with mid-range dampers, making it suitable for balanced setups that prioritize both comfort and response. Proper installation requires measurement of ride height and confirmation that damper travel limits and suspension geometry remain within safe operating parameters; consult your coil-over kit manufacturer's specifications for correct pairing with compatible damper bodies and mounting hardware.
