Spacer 2.25in ID

Eibach Spacer Coupling 2.25in ID – Precision Suspension Spacer for Coil Spring Systems When suspension tuning comes down to the details, the smallest components make the biggest difference. The Eibach Spacer Coupling 2.25in ID (Part #SPACER225) is engineered to provide perfect spring alignment and preload consistency in dual-rate or stacked coilover systems. Designed to fit 2.25-inch inside-diameter coil springs, this precision-machined coupling ensures your suspension operates smoothly, predictably, and without deflection — corner after corner, mile after mile. Built for racers, fabricators, and performance enthusiasts, this coupling represents Eibach’s commitment to exact tolerances and world-class quality. Whether you’re chasing podiums or refining your street build, this hardware delivers the precision and reliability your suspension demands. Built for Precision and Durability Each Eibach spring coupler is CNC-machined from high-grade billet aluminum to maintain perfect concentricity between coil springs. The lightweight design minimizes unsprung mass while providing structural strength that resists deformation under load. A sleek black anodized finish protects the surface from corrosion and abrasion, ensuring longevity even in high-temperature or high-vibration environments. Specifications: Material: Billet Aluminum Finish: Black Anodized for Corrosion Resistance Inside Diameter: 2.25 in (57 mm) Configuration: Single Coupler / Spacer Use: Coilover & Dual-Rate Spring Systems This component eliminates coil misalignment, prevents unwanted bowing, and maintains a perfectly uniform load path — improving both consistency and overall suspension feel. Optimized for Coilover and Dual-Rate Applications The Eibach 2.25in Spacer Coupling is designed to connect the main and tender (or helper) springs in a dual-rate setup. It keeps the spring stack precisely centered on the shock body, enabling a smooth transition between rates without chatter or misalignment. Ideal Applications: Off-Road Racing / Pre-Runners: Maintains spring alignment under aggressive bump and rebound cycles. UTV / SXS Performance: Delivers consistent preload and travel control through demanding terrain. Track & Street Builds: Provides repeatable corner balance and damping response for precision tuning. Custom Fabrication Projects: Offers professional-grade fitment for coilover conversions or custom suspension assemblies. By maintaining exact spring geometry, this coupler ensures predictable handling, reduced friction, and improved shock performance under load. Lightweight Strength, Professional Fitment Eibach’s precision machining and anodizing process guarantee long-term durability in racing or daily-driven environments. The coupling’s engineered stiffness resists distortion even under high-rate springs, maintaining true preload values and maximizing spring lifespan. Prevents side loading and coil deflection Maintains preload accuracy for consistent ride height Reduces friction for smoother operation Designed to withstand race-level forces and heat cycles Every part is manufactured under strict Eibach quality standards — the same processes used in their championship-winning suspension systems.
