Eibach ERS 8.00 inch L x 2.25 inch dia x 600 lbs Coil Over Spring - Universal Fit
The Eibach ERS 8.00 inch L x 2.25 inch dia x 600 lbs Coil Over Spring delivers precise spring rates for custom coilover setups in drag racing, road racing, and autocross. Designed for 2.25 inch inside diameter shocks from brands like QA1, Bilstein, and Fox, this spring provides consistent performance under high loads. It supports vehicles needing stiff rear or front suspension for better traction and control.
Key Features
- High-Tensile Chrome Silicon Steel: Custom-wound alloy resists fatigue for extended track use and repeated high-stress cycles.
- Shot-Peened Finish: Reduces surface stress by up to 40% compared to standard springs, ensuring longer service life in demanding conditions.
- Ground Flat and Square Ends: Ensures secure, repeatable seating on perches for accurate ride height and no side-loading.
- Progressive Rate Design: Maintains smooth initial response with firm support at full compression, minimizing body roll.
- Color-Coded Identification: Purple stripe for 600 lb/in rate allows quick sorting in pit or shop environments.
Product Notes
- Inspect shock body diameter before purchase; fits standard 2.25 inch ID coilover housings.
- Store in dry conditions to preserve steel integrity and prevent corrosion.
- Ships as single spring; order pairs for axle applications.
Installation Notes
- Professional installation recommended.
- Preload spring 1-2 inches maximum; measure compressed height to avoid bottoming.
