Construction & Design The Eibach ERS Main Metric Linear Tender Spring is crafted from premium steel alloys that provide excellent tensile strength and fatigue resistance. Its precise manufacturing process ensures a consistent spring rate and minimal manufacturing tolerances, which are crucial for high performance tuning. The spring features a linear rate profile, meaning the force required to compress the spring increases proportionally with displacement, resulting in predictable handling characteristics. The design emphasizes durability and stability, with a finish that resists corrosion and environmental wear. Its compact and lightweight construction allows for easy installation and integration into existing suspension setups. The spring's geometry is optimized for racing applications, providing a balance between compliance and control, which helps improve tire contact and overall vehicle handling. Installation & Fitment The Eibach ERS Main Metric Linear Tender Spring is designed as a bolt in upgrade for compatible racing and high performance vehicles. Installation typically involves replacing existing springs with the ERS spring, and no additional modifications or tuning are usually required. However, it is recommended to verify compatibility with your specific vehicle and suspension setup before installation. Proper spring rates and lengths should be selected based on your vehicle's weight, handling goals, and racing requirements. For optimal performance, professional installation and alignment are advised to ensure the suspension geometry remains within optimal parameters.
