Built for use with compatible coilover systems, this linear main spring helps optimize handling balance, suspension response, and vehicle control across a wide range of track configurations.\u003c\/p\u003e\u003cp\u003eEibach race springs are engineered to provide maximum suspension travel while maintaining a compact block height. Their highly linear spring rate delivers predictable performance through the full range of compression, while stringent manufacturing and testing standards help ensure consistent results from one spring to the next. The lightweight design also helps reduce unsprung mass, supporting sharper suspension response and improved tire contact.\u003c\/p\u003e\u003cp\u003eThe Eibach ERS lineup offers extensive rate and size combinations for custom suspension development, making this spring suitable for race teams, performance builders, and enthusiasts fine-tuning a vehicle for circuit, autocross, or other competition use. The spring is identified by its 64 mm inside diameter and 102 mm free length, allowing it to be matched with coilover hardware designed for those specifications. Verify spring rate, perch compatibility, and application requirements before installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat's Included:\u003c\/strong\u003e One Eibach ERS linear main coilover spring.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e Universal motorsport application; fitment depends on compatible coilover hardware, spring rate requirements, and vehicle suspension configuration.
