Coilover Spring Silver 3.00in ID

The Coilover Spring Silver 3.00in ID from EIBACH is a premium replacement coil spring engineered for custom suspension builds and performance-oriented vehicle modifications. Whether you're fine-tuning ride height on a street car, building a show-quality lowered setup, or assembling a complete coilover kit, this spring delivers the consistent spring rate and durability you need for years of reliable service. Designed with a 3.00-inch inner diameter, it integrates seamlessly into most modern coilover assemblies and pairs with compatible dampers to create a fully adjustable suspension platform.

EIBACH's silver-finished coil spring is manufactured to tight tolerances, ensuring uniform spring rate across the entire compression range and preventing the bind or inconsistency common in lower-grade alternatives. The 3.00-inch bore specification is critical—it directly affects how the spring seats on the damper rod and controls vertical load transfer during acceleration, braking, and cornering. This spring's consistent linear rate means predictable handling characteristics and improved suspension geometry maintenance, essential for drivers who demand repeatable performance whether on the road or autocross course. The robust construction resists fatigue cracking, a common failure mode in budget springs subjected to repeated compression cycles.

This coilover spring benefits builders assembling custom suspension systems, experienced mechanics upgrading original equipment springs, and enthusiasts seeking modular replacement components for adjustable dampers. Installation requires removal of the original spring and damper assembly; proper spring compressors and safety equipment are essential during setup. Verify your coilover platform's inner diameter specification before purchase—the 3.00-inch ID must match your damper sleeve for correct seating and performance. The 5.5-pound weight makes handling manageable, and the 15-inch length accommodates standard ride-height adjustments typical of road and track-focused builds.
