Eibach Spacer 2.5in ID

Eibach Spacer Coupling 2.50in ID – Precision Coilover Coupler for Professional Suspension Systems

When your suspension demands accuracy and performance, every detail matters. The Eibach Spacer Coupling 2.50in ID (Part #SPACER250) is engineered to deliver exact spring alignment, consistent preload, and dependable performance under even the harshest conditions. Designed to fit coil springs with a 2.50-inch inside diameter, this spacer coupling ensures a perfectly centered interface between stacked or dual-rate springs — keeping your suspension geometry precise and your performance predictable.

Built to the same standards as Eibach’s world-famous racing springs, this coupler is ideal for race cars, off-road vehicles, and custom fabrication projects that demand flawless suspension behavior.

Engineered with Eibach’s Racing Heritage

Each Eibach spring coupler begins with premium billet aluminum precisely CNC-machined to tight tolerances. The result is a lightweight yet rigid component that perfectly matches the coil’s inner diameter, keeping springs true and centered during compression.

The black anodized finish not only looks professional but provides durable protection from corrosion, abrasion, and high-temperature environments. From desert racing to road courses and street performance builds, this spacer coupling is designed to last a lifetime.

Specifications:

• Material: Billet aluminum

• Finish: Black anodized

• Inside Diameter: 2.50 in (64 mm)

• Configuration: Single coupler / spacer

• Compatibility: 2.50in ID coil springs

This coupler ensures a perfectly uniform load path through your spring stack, minimizing deflection, improving consistency, and extending component life.

Built for Coilover and Dual-Rate Spring Systems

The Eibach Spacer Coupling 2.50in ID is purpose-built for dual-rate coilover systems. When combined with a main and tender spring, it maintains alignment and prevents binding during compression cycles. The result is a smoother, more controlled suspension response with seamless transitions between spring rates.

Ideal Applications:

• Off-Road & Desert Racing: Maintains alignment through high-speed whoops and long-travel compression.

• Track & Street Performance: Supports accurate preload tuning and consistent spring rate changes.

• Custom Fabrication Projects: Perfect for coilover conversions, chassis upgrades, and custom race car builds.

• UTVs & SXS: Keeps coil stacks secure and centered under demanding trail or competition use.

Eibach’s precision couplers eliminate unwanted spring movement, giving you a suspension setup that feels tighter, smoother, and more predictable from the first corner to the last mile.

Lightweight Strength & Long-Term Durability

Every Eibach coupling spacer is built for repeatability. The machined aluminum structure resists deformation under high load, while the anodized coating protects against the constant friction of coil movement. The coupler’s design maintains perfect parallelism and consistent spacing, ensuring your coilover performs the same on lap 100 as it did on lap 1.

• Prevents spring bowing and misalignment

• Reduces friction and wear between stacked coils

• Retains dimensional accuracy through repeated compression cycles

• Designed for high-load, high-temperature racing environments

This is a professional-grade solution that complements Eibach’s full ERS spring lineup, giving builders a cohesive, precision-fit system.
