Eibach Spacer Coupling 2.36in ID

Eibach Spacer Coupling 2.36in ID – Precision Spring Alignment for Maximum Suspension Performance

When it comes to suspension tuning, precision is everything. The Eibach Spacer Coupling 2.36in ID delivers the exact fit and repeatable performance demanded by racers, fabricators, and performance enthusiasts alike. Designed to mate perfectly with 2.36-inch inside-diameter coil springs, this coupling allows for seamless stacking, fine-tuning of spring preload, and improved overall spring consistency — ensuring your suspension performs exactly as engineered, every lap or every mile off-road.

Eibach’s heritage in motorsports runs deep. With decades of championship-proven performance across off-road racing, road racing, and OEM development, every component they produce is built to deliver the precision, repeatability, and long-term reliability that serious builders demand. This spacer coupling is no exception — crafted to the same exacting tolerances as Eibach’s legendary coil springs.

Engineered for Strength, Precision, and Consistency

Each Eibach spring coupler starts as a billet of high-grade aluminum and is CNC-machined for perfect concentricity. The result is a coupler that keeps your coil stack perfectly centered under compression, eliminating unwanted side loading and maintaining consistent motion through the entire stroke.

• Material: Lightweight aluminum alloy

• Finish: Black anodized for corrosion resistance and a professional appearance

• Inner Diameter: 2.36 inches (60 mm)

• Configuration: Single coupler / spacer

That black anodized finish isn’t just for looks — it adds a protective oxide layer that resists wear from constant preload changes, vibration, and environmental exposure. Whether your car sees desert silt, track rubber, or daily-driver conditions, this coupler is built to last.

Ideal for Coilover and Dual-Rate Spring Systems

If you’re running a dual-rate coilover setup, the spacer coupling serves a crucial role in how your springs transition between the tender (helper) and main springs. By using a precise 2.36 ID coupler, Eibach ensures both springs stay perfectly aligned on the shock body, allowing for smooth load transfer and predictable handling behavior.

Builders use these couplers in a variety of applications:

• Off-Road Suspension: Keeps coil stacks aligned under heavy articulation and bump travel.

• Track & Street Performance: Enables precise preload adjustment and linear spring behavior in custom coilover kits.

• Custom Fabrication Projects: Perfect for suspension builders creating bespoke systems for race trucks, hot rods, and drift cars.

The coupler’s lightweight construction minimizes unsprung mass, while its rigidity prevents deflection under high loads — exactly what you need for consistent damping and cornering stability.

Eibach Quality: Tested, Trusted, Proven

Every Eibach component goes through extensive material and performance testing before it earns the Eibach name. Their manufacturing facilities operate under ISO-certified quality systems and employ precision German and U.S. manufacturing standards to maintain repeatability across every part.

That means when you pair an Eibach spacer coupling with an Eibach spring, you’re using components engineered to work together. The fit, finish, and tolerances are exact — no slop, no guesswork. It’s this attention to detail that makes Eibach a go-to brand for championship-winning race teams and OEM programs alike.

Key Advantages:

• Guaranteed fit for 2.36-inch ID coil springs

• Black anodized aluminum resists corrosion and wear

• Supports consistent preload and spring alignment

• Ideal for multi-rate and adjustable coilover systems

• Backed by Eibach’s world-renowned performance heritage

Designed for Builders Who Demand Perfection

Whether you’re assembling a full custom coilover setup for a pre-runner, dialing in corner weights on your road course car, or building a suspension for a desert race vehicle, the SPACER60 coupler helps eliminate one of the most common variables in suspension performance — coil misalignment.

When springs aren’t perfectly centered, it can cause uneven compression, loss of damping consistency, and accelerated wear on both springs and shock hardware. Eibach’s couplers eliminate these issues, providing a perfectly flat, concentric interface that translates into:

• Better handling precision

• Reduced spring fatigue

• Easier corner balancing and setup repeatability

For professional builders and DIY enthusiasts alike, this is one of those subtle upgrades that separates an average suspension setup from a championship-level one.

Technical Specifications

Application Examples

• UTV / SXS: Ideal for performance shock rebuilds or custom coilover conversions where precise preload tuning is critical.

• Desert Trucks / Pre-Runners: Maintains alignment through long-travel suspension cycles, reducing side-load stress on shocks.

• Track Cars / Time Attack Builds: Enables quick spring-rate changes and fine preload tuning without compromising geometry.

• Classic / Custom Vehicles: Perfect for modernizing older chassis with adjustable coilovers or custom spring setups.

Optimize, Tune, and Dominate

Suspension tuning isn’t just about spring rate — it’s about how each component interacts under load. The Eibach 2.36in ID Spacer Coupling gives you one more tool to perfect that interaction. It’s the small details like this that define great setups: consistent geometry, smooth transitions, and a stable platform that inspires confidence on every surface.

If you’re serious about dialing in performance, trust the brand that builds for champions — and the retailer that builds for racers.
