Eibach ERS 6.00 inch L x 2.50 inch dia x 300 lbs Universal Coil Over Spring
Eibach ERS coilover springs deliver precise 300 lb/in spring rates in a compact 6.00-inch length and 2.50-inch inside diameter design for custom coilover applications. This universal spring fits 2.5-inch body diameter shocks from brands like Penske, Bilstein, Fox, and Ohlins used in drag racing, road course, and autocross setups. Engineered for consistent performance, it maintains rate under high loads for sharper handling and faster lap times.
