Eibach ERS Coilover Springs - Race-Grade Performance

Eibach ERS (Eibach Race Springs) represent the world's most comprehensive and trusted race spring system, engineered to the same uncompromising standards relied upon by the most demanding motorsport programs globally — including Formula 1, WRC, Le Mans, and NASCAR. Whether you're building a dedicated track car, a high-performance street machine, an off-road competitor, or a professional race vehicle, the ERS line delivers the consistency, linearity, and durability that serious suspension tuning demands.

Key Features:

• Motorsport-proven precision — manufactured to industry-leading tolerances for consistent spring rate, linearity, and static height across every unit in the line
• Ultra-lightweight Hi-Ten spring steel construction — premium high-tensile steel reduces unsprung mass for improved suspension response and handling dynamics while delivering superior fatigue resistance
• Maximum travel with minimal block height — optimized geometry delivers greater usable suspension travel without sacrificing ground clearance
• Exceptional block resistance and durability — engineered to withstand repeated compression cycles without fatigue or permanent set
• Precision parallel and square end configurations — maintained under both loaded and unloaded conditions for accurate, consistent spring seating
• Minimal side loading — load center is ideally positioned relative to the spring axis, reducing friction and premature shock absorber wear
• Individually tested and verified — every spring is tested and rated before leaving the factory
• Durable powder coat finish — corrosion-resistant coating ensures lasting protection across all operating environments

Comprehensive Range of Rates and Configurations:

The ERS line spans an extensive catalog of spring rates and configurations to suit virtually any performance application. By combining ERS Main, Tender, and Helper springs, suspension engineers and enthusiasts alike can create the ideal spring rate combination for their specific setup — from street performance and dedicated track builds to off-road and professional motorsport.

Backed by decades of OEM and motorsports engineering expertise, every Eibach ERS spring reflects a commitment to precision, consistency, and race-proven performance that has made it the original spring trusted by racers around the world.
