Will these springs fit any 2.0 coilover shock?
These springs fit most 2.0 coilover shocks that use a 2.5" inside diameter spring. Always verify your shock manufacturer's spring specifications before ordering.
What does 2.5" I.D. mean?
The 2.5" I.D. measurement refers to the inside diameter of the spring. This dimension must match your coilover shock's spring hardware and retainers.
How do I determine the correct spring rate?
Spring rate selection depends on vehicle weight, suspension geometry, motion ratio, desired ride height, and intended use. Heavier vehicles typically require higher spring rates than lighter vehicles. You can watch our tutorial on Calculating Spring Rates for more information.
Can these springs be used in a dual-rate coilover setup?
Yes. Eibach 2.5" coilover springs are commonly used in both single-rate and dual-rate suspension systems for improved suspension tuning flexibility.
Are these springs sold individually?
Yes. Springs are sold individually. Most vehicles require two springs per axle, while dual-rate coilover systems may require four springs per axle.
Are Eibach Off-Road Coilover Springs durable?
Yes. ERO springs are engineered to maintain rate and free length even after repeated full compression cycles. They are designed to handle:
- Extreme suspension cycling
- High heat environments
- Heavy unsprung weight
- Continuous race abuse
Are these coilover springs block-stable?
Yes. In dual-rate setups, the tender spring is often designed to fully compress (block) to transition into the main spring. ERO springs are built to:
- Safely block repeatedly
- Maintain consistent transition points
- Resist sagging or rate loss
