Eibach Spacer Coupling 3.00in ID – Precision Coil Spring Spacer for Professional Suspension Tuning When precision suspension tuning matters most, every component in your setup need s to perform flawlessly. The Eibach Spacer Coupling 3.00in ID (Part #SPACER300) is engineered to maintain perfect spring alignment and preload consistency in the most demanding race, street, or off-road conditions. Designed to fit coil springs with a 3.00-inch inside diameter, this coupling delivers the precision, durability, and repeatability that define Eibach’s world-class suspension hardware. Whether you’re building a long-travel off-road coilover, dialing in a road course setup, or fabricating a custom dual-rate spring system, this spacer coupling keeps your suspension geometry exact and your performance consistent. Built for professionals but trusted by enthusiasts, Eibach’s spring couplers are the hidden heroes behind some of the most finely tuned suspensions in motorsports. Engineered with Eibach’s Signature Precision The Eibach 3.00in ID spacer coupling is CNC-machined from high-grade aluminum for unmatched strength and perfect concentricity. Its lightweight design minimizes unsprung mass while maintaining rigid structural support between springs. The coupler is then hard-anodized in black for superior corrosion resistance, ensuring long-term durability in any environment — from the dust and heat of desert racing to the wet grit of endurance circuits. Every detail is engineered to eliminate unwanted spring movement and maintain a perfectly centered load path. The result is smoother operation, improved consistency in damping response, and longer spring life. Key Specifications: Material: CNC-Machined Aluminum Finish: Black Anodized for Corrosion Resistance Inside Diameter: 3.00 inches (76 mm) Application: Coilover / Dual-Rate Spring Systems Configuration: Single Spacer Coupling Optimized for Dual-Rate and Coilover Applications In multi-spring coilover systems, maintaining spring alignment during compression is critical. The Eibach Spacer Coupling provides a precision interface between main and tender (helper) springs, ensuring that load transitions remain smooth and predictable. When paired with Eibach ERS springs, this coupler guarantees a perfect fit between the upper and lower coils. Its inner chamfer and precise diameter control allow the springs to operate concentrically along the shock body, minimizing deflection and maximizing contact surface area. Ideal Use Cases: Off-Road Coilovers: Keeps coil stacks perfectly aligned through long-travel suspension cycles and harsh impact conditions. Performance Track Builds: Enables precise preload tuning and consistent corner balancing under high lateral G-loads. Custom Fabrication Projects: Provides professional-grade alignment for coilover conversions, restomod chassis, and race-spec suspension systems. UTV & Desert Racing Applications: Maintains preload integrity and spring rate consistency during extreme articulation and vibration. Built for Strength, Longevity, and Accuracy Eibach’s commitment to quality goes far beyond manufacturing tolerances — it extends to materials science, heat treatment, and precision machining practices that ensure every component meets or exceeds motorsport standards. This spacer coupling is designed to handle the same dynamic forces that Eibach’s racing springs endure. Its anodized surface reduces friction and prevents galling under heavy compression cycles, while the structural design maintains dimensional stability through repeated load transitions. Even under continuous race conditions, the coupling won’t deform, gall, or introduce unwanted play into the spring assembly. You get consistent preload, linear compression, and the confidence that your setup will behave predictably, lap after lap or mile after mile. Eibach Quality: Proven Worldwide in Professional Motorsport From Formula 1 to King of the Hammers, Eibach components have become the gold standard for high-performance suspension systems. Each part, including this 3.00in ID spacer coupling, is designed, tested, and manufactured with the same standards that power championship-winning vehicles around the world. Why builders choose Eibach: Trusted by professional motorsport teams for reliability and accuracy Manufactured under ISO 9001 and QS 9000-certified processes Extensive R&D, material testing, and in-house quality control Seamless integration with Eibach’s ERS (Eibach Race Spring) system Eibach doesn’t just make parts — they engineer systems. That’s why when you integrate genuine Eibach hardware, every component works in harmony to deliver predictable, repeatable performance across your entire suspension system.
