Spring Coilover 12in x 2.5in

The Eibach Spring Coilover 12in x 2.5in is a precision suspension component engineered for enthusiasts and mechanics seeking a tunable ride quality upgrade. This coilover spring fits into performance suspension systems where adjustability and consistency matter—whether you're fine-tuning street handling, building a track-focused platform, or dialing in a custom lowering setup. Eibach's reputation for engineering reliability makes this component a trusted choice for suspension builds where real-world performance justifies the investment.

At 12 inches in length with a 2.5-inch coil diameter, this spring delivers the linear spring rate consistency Eibach is known for, enabling predictable suspension behavior across compression and rebound cycles. The coilover design allows independent spring preload adjustment, letting you raise or lower ride height without compromising spring rate—a critical advantage over conventional springs when you need precise geometry tuning or clearance control. At 5.11 pounds, the spring's weight distribution contributes to reduced unsprung mass, improving wheel articulation and responsiveness during dynamic driving conditions.

This coilover spring pairs seamlessly with adjustable dampers and suspension platforms designed for modular coilover assembly, making it ideal for track builders, street enthusiasts, and mechanics upgrading suspension geometry on vehicles that benefit from fine-tuned handling balance. Verify fitment against your specific vehicle's suspension tower and damper compatibility before ordering, as coilover integration requires accurate measurement and proper damper pairing for optimal performance. Installation should be performed by experienced technicians familiar with suspension geometry and preload adjustment protocols.
