Spring 140mm Coil-Over 60mm ID

The Spring 140mm Coil-Over 60mm ID from EIBACH is a precision-engineered coil spring designed for high-performance suspension systems and custom coil-over setups. This metric-standard spring serves users who demand reliable, tunable suspension geometry—from motorsport enthusiasts to suspension shops building bespoke installations. The 140mm free length and 60mm inner diameter make this spring compatible with professional coil-over assemblies where adjustability and consistent ride control are critical.

Manufactured from high-quality steel with a protective red powder coat finish, this coil-over spring delivers a 1256 lb/in spring rate—a moderate-to-firm rate suitable for street-performance and entry-level track applications. The powder-coat exterior resists corrosion and road contamination, extending service life in harsh environments. EIBACH's metric design ensures precise fitment within OEM and aftermarket coil-over platforms, while the 60mm ID accommodates standard shock body diameters found in modern suspension kits. The spring's engineering prioritizes consistent load support and predictable damping interaction across the vehicle's range of motion.

This spring is ideal for suspension builders, repair shops, and enthusiasts upgrading factory suspension or building custom coil-over assemblies. Installers should verify compatibility with their shock's body diameter and confirm that the 1256 lb/in rate matches their vehicle's weight distribution and intended use—stiffer rates suit performance driving, while this moderate rate balances comfort with handling improvement. Proper installation requires centering the spring on the shock body and torquing all fasteners to OEM specification to prevent premature wear or misalignment.
