Eibach 140-60-0160 Metric Coilover Main Spring 60mm ID

The Eibach 140-60-0160 is a precision-engineered ERS (Eibach Race Spring) Main Spring designed for high-performance coilover suspension systems. Featuring a 60mm inner diameter, this metric coilover spring serves as the primary load-bearing component in Eibach's renowned double-spring system, delivering the muscle needed to transform engine power into optimal track adhesion.

ERS Double-Spring System:

This Main spring is part of Eibach's modular ERS system, which offers over 700 individual spring components that can be combined to create nearly unlimited suspension configurations. The Main spring features a linear-rate characteristic and determines the final spring rate of your suspension system. When paired with a Tender spring, the system provides a softer initial rate during combined compression, then transitions to the firmer Main spring rate once the Tender spring fully closes—delivering precise control over suspension behavior during cornering, acceleration, and braking.

Key Features:

• 60mm inner diameter metric coilover design for precision fitment
• Linear-rate characteristic for predictable, consistent performance
• High spring travel and deflection capacity at compact mounting lengths
• Shot-peened surface treatment for enhanced durability
• Superior corrosion protection through phosphating and epoxy coating
• Manufactured to precise tolerances for reliable performance
• High dynamic durability ensures long component life under racing conditions
• Block resistance to prevent coil binding
• Clearly imprinted with part number, spring rate, and physical dimensions for easy identification
• Compatible with Eibach Helper springs to prevent looseness at full droop

Engineered for serious suspension tuning, this Main spring works seamlessly with Eibach Tender springs, Helper springs, and connecting plates to achieve the perfect balance between compliance and control. Whether you're a professional suspension engineer or a weekend track enthusiast, the Eibach ERS system provides unmatched performance and flexibility for your racing application.
