Spring 12in Coil-Over 3.0in ID Silver

The Spring 12in Coil-Over 3.0in ID Silver from EIBACH represents precision suspension engineering for enthusiasts and mechanics seeking adjustable ride height and performance tuning. This 12-inch coil-over spring with a 3.0-inch inner diameter is engineered for custom suspension builds where independent spring rate selection and height adjustment are critical to achieving desired handling characteristics. Whether you're setting up a street performance platform, preparing for autocross competition, or dialing in a lowered stance, this silver-finished coil-over spring delivers the foundation needed for predictable suspension geometry and load control.

EIBACH's coil-over design allows you to separate spring rate tuning from ride height adjustment—a critical advantage when optimizing corner weights and anti-squat characteristics. The 3.0-inch bore specification ensures compatibility with standard coil-over shock bodies and tower mounts common in performance suspension applications. The silver finish provides corrosion resistance and a clean aesthetic, while the 12-inch length accommodates both lowering and performance setups without sacrificing suspension travel. At 4.81 lbs, this spring maintains the lightweight profile expected from modern performance suspension components, reducing unsprung mass and improving responsiveness through direction changes.

This coil-over spring is ideal for builders and tuners working on track-focused platforms, drift builds, or street cars requiring adjustable suspension geometry. Proper installation requires compatible shock absorbers with matching 3.0-inch bore diameters and appropriate mounting hardware for your vehicle's chassis. Suspension setup should account for spring rate selection, preload adjustment, and damping ratios to ensure stability and comfort across intended driving conditions. Always verify fitment with your specific coil-over system and consult suspension geometry data when making height or spring rate changes.
