11in x 5.5in x 1200# Front Spring

The 11in x 5.5in x 1200# Front Spring by EIBACH is engineered for automotive enthusiasts and mechanics seeking precise suspension geometry control and improved ride quality. This front spring delivers the load-carrying capacity and natural frequency tuning necessary for performance-oriented builds, whether you're upgrading a daily driver or refining a track-focused platform. EIBACH springs are foundational components in any serious suspension package, working in concert with dampers and geometry to define how a vehicle corners, accelerates, and absorbs road input.

At 1200 pounds per inch rate, this coil spring exhibits moderate stiffness—stiffer than OEM springs yet accessible for street applications without sacrificing ride comfort or bottoming-out risk under normal driving conditions. The 11-inch free length and 5.5-inch working diameter provide fitment compatibility across a broad range of production and modified vehicles, allowing integrators to maintain proper ride height and chassis balance. EIBACH's manufacturing tolerances and material quality ensure consistent spring rate across the production lot, critical for paired-spring installations where mismatches introduce handling unpredictability and uneven load distribution.

This front spring suits owners upgrading suspension stiffness for road course driving, autocross, or street performance without resorting to coilover packages. Mechanics and fabricators favor EIBACH springs for OEM-replacement work and custom builds alike; the 14.17-pound weight reflects a durable, multi-layer design. Always verify fitment against your specific vehicle platform and existing suspension components before installation, and consider pairing with complementary rear springs and quality dampers to optimize overall system performance and longevity.
