Eibach ERS 7.00 inch L x 2.50 inch dia x 600 lbs Coil Over Spring - Universal Coilover Fitment
The Eibach ERS 7.00 inch L x 2.50 inch dia x 600 lbs Coil Over Spring delivers precise spring rate control for custom coilover setups in drag racing, autocross, and street performance vehicles. This universal spring installs on 2.50 inch inner diameter coilover shocks, providing consistent damping response and reduced body roll under load. Engineered for high-stress environments, it maintains shape and rate through repeated heat cycles and impacts.
Key Features
- Exact Specifications: 7.00 inch free length, 2.50 inch inner diameter, 600 lbs per inch rate ensures perfect match for medium-stiff front or rear coilover applications.
- Chrome Silicon Steel: Ultra-high tensile strength material resists fatigue, supports heavy loads, and retains rate over thousands of cycles.
- Shot Peened Construction: Increases surface strength by 200%, with preset, double-tempered, and stress-relieved process for flat seating and load stability.
- Powder Coated Finish: Black oxide coating prevents corrosion in harsh conditions, from track days to salted roads.
- Ground Square Ends: Precision-ground ends promote even perch contact, eliminating bind and ensuring smooth compression.
Product Notes
- Pair with 2.50 inch ID coilover shocks from brands like QA1, Bilstein, or Fox for seamless integration.
- Inspect for proper wire diameter compatibility (0.875 inch typical) before installation.
- Standard ground shipping; no oversize fees or LTL required.
Installation Notes
- Professional installation recommended.
- Requires adjustable perches or collars for ride height tuning.
- Compatible with most threaded body coilover shocks; use threadlocker on locknuts.
