Coilover Spring 20in 3.75in ID Silver

The EIBACH Coilover Spring 20in 3.75in ID Silver (MPN: 2000.375.0400S) is a precision-engineered suspension component designed for serious enthusiasts and professional mechanics who demand tunable ride height and spring rate control. Built for street and track applications, this coilover spring serves as the foundation for custom suspension geometry, allowing you to dial in handling characteristics that factory setups simply cannot achieve.

At 20 inches in length with a 3.75-inch inner diameter, this coilover spring is engineered to integrate with compatible strut housings and damper bodies in mid-size and performance vehicle platforms. The silver zinc-plated finish provides corrosion resistance under harsh road salt and moisture exposure, critical for long-term reliability in seasonal climates. EIBACH's manufacturing standards ensure consistent spring rate linearity across the entire compression range, eliminating the soft initial compliance or binding that plagues inferior springs.

Mechanics and tuners deploying this coilover spring will appreciate its robust construction, designed to withstand thousands of suspension cycles without permanent set or rate degradation. This product is ideal for those building dedicated road course platforms or refining daily driver dynamics, delivering the consistency and adjustability that separates competent builds from exceptional ones.
