Eibach Spring Couplers (often called spacers) let you stack multiple springs—such as a main and a tender (or helper) spring—into a single coilover assembly. This approach allows for more precise control over spring rates and ride characteristics.

Why Use Eibach Spring Couplers?

  • Connect Main and Helper Springs: Couplers serve as a bridge, allowing two springs of different rates or lengths to work together in one shock.
  • Inside Diameter Options: Eibach offers these spacers in various diameters to match the most common coilover spring sizes.
  • Fine-Tuning Suspension: Stacking multiple springs lets you achieve a progressive or dual-rate setup without switching out an entire spring set.

Features and Construction

  • CNC Machined Aluminum: Each spacer is produced to tight tolerances for a secure fit.
  • Anodized Black Finish: The anodizing process guards against corrosion and wear.
  • Lightweight and Durable: Despite their sturdy build, these couplers add minimal weight to your suspension.

How Eibach Spring Couplers Work

When two springs are stacked on a single shock, the coupler keeps them in place. As your suspension moves, each spring compresses or expands based on its individual rate. The coupler maintains separation between the springs and transfers load from one spring to the other as needed.

Benefits of a Coupled Spring Setup

  • Progressive Performance: A tender spring can take up smaller bumps while the main spring handles heavier impacts.
  • Ride Customization: Choose different rates to adjust travel, comfort, and handling without changing your entire spring set.
  • Versatile Upgrade: Great for track cars, off-road rigs, or any build needing more control over spring behavior.

Things to Keep in Mind

  • Correct Sizing: Always confirm the inner diameter of your springs to ensure the spacers fit properly.
  • Installation: While couplers are straightforward, compressing springs can be dangerous. Consider professional installation if you’re unsure.
  • Matching Components: Use springs and couplers from reputable manufacturers to avoid fitment or durability issues.

Eibach Spring Couplers offer a simple way to run a multi-spring setup, giving you more control over your ride’s comfort and handling. Whether you’re chasing better on-track performance or improved off-road control, these spacers are built to provide reliable, consistent results.
