Eibach ERS 120mm Length x 60mm ID Coil-Over Spring 120-60-0140

This Eibach ERS coil-over spring measures 120mm in free length with a 60mm inside diameter and 14.0 kg/mm spring rate, designed for custom coilover strut assemblies in racing and performance applications. It fits any coilover system with matching 60mm ID perches, delivering consistent damping control and precise cornering response. Built for endurance racing, it withstands high-stress track conditions while maintaining shape over repeated cycles.

Key Features

  • Spring Rate: 14.0 kg/mm (784 lb/in) provides balanced stiffness for aggressive handling and stability under load.
  • Dimensions: 120mm free length x 60mm ID x 70mm OD ensures compatibility with standard coilover perches and strut bodies.
  • Material: High-tensile chrome-silicon steel alloy resists fatigue for long-term durability in motorsports.
  • Manufacturing Process: Quadruple shot-peened, heat-treated, tempered, and stress-relieved for reduced breakage risk and consistent performance.
  • End Design: Precision ground flat and square ends lock securely into perch seats for maximum contact and energy transfer.

Coilover Springs

Coilover Springs

Coilover springs are the replaceable compression springs that wrap around the shock body in a coilover assembly, determining ride height, spring rate, and the balance between comfort and handling stiffness. Swapping springs is the most direct way to tune a coilover setup for a new application without buying an entirely new system.Popular UpgradesLinear-rate springs in the 6 to 12 kg/mm range are the most popular choice for street performance and track day builds where predictable handling is more important than maximum compliance. Progressive-rate springs that soften on small bumps and stiffen under load are preferred for street cars that need to be both comfortable on rough roads and controlled in hard cornering. ID60 and ID65 springs are the most common inner diameter specifications across popular coilover platforms.What is the difference between linear and progressive coilover springs?A linear spring has a constant rate from full droop to full compression, providing consistent an...
