Spring 8in Coil-Over 2.5in ID

The Eibach Spring 8in Coil-Over 2.5in ID is a precision-engineered suspension component designed for vehicle builders and performance enthusiasts who demand control over ride height and handling characteristics. This coil-over spring serves as the foundation of modern lowering and adjustable suspension systems, allowing drivers to dial in exactly the spring rate and geometry their application requires. Whether you're building a track-focused platform or fine-tuning street performance, this 8-inch spring provides the stiffness and durability needed for repeatable, predictable suspension behavior.

Manufactured from high-tensile steel and finished in durable red powder coat, the Spring 8in Coil-Over 2.5in ID features a robust 375 lb/in spring rate—a mid-range stiffness that balances compliance for street driving with sufficient support for aggressive cornering and load transfer. The 2.5-inch inner diameter (ID) specification ensures compatibility with standard coil-over shock bodies, making integration straightforward when paired with quality dampers. At 8 inches in length, this spring compresses predictably under load while maintaining consistent ride height across varying terrain, and the red powder coat resists corrosion and UV degradation over extended use.

This spring is ideal for owners upgrading to adjustable coil-over kits, as the 375 lb/in rate works well across sedan, coupe, and lightweight sport-utility platforms without requiring exotic dampening or chassis reinforcement. Mechanics and suspension shops stock this specification because it balances affordability with performance across multiple vehicle classes. Proper installation requires matching the spring to a compatible shock body with 2.5-inch ID and ensuring correct preload adjustment during assembly. Individual spring purchase allows selective replacement or custom spring rate mixing for fine-tuned suspension tuning.
