Eibach ERS Platinum 14 in. Rear Racing Spring, 3.50 in. Outside Diameter, 130 lb/in Rate

Eibach PLATINUM series race springs are engineered using our proprietary ultra-high tensile strength steel, for the lowest physical weights and maximum spring travel. More Travel / Deflection than Standard Racing Coil Springs

• The Eibach ER Platinum Springs will Maintain Their Dimensions and Rates to Incredibly Tight Tolerances, Lap after Lap, Race after Race
• Flat-Ground End Configuration with Parallel Tolerance to +/-1 Degree
• Ultra Light-Weight Using High Tensile Steel
• Block Resistant - No Loss in Spring Height!

The Eibach ERS Platinum rear racing spring is engineered for demanding motorsports applications where consistent performance, reduced weight, and extended suspension travel are essential. Manufactured from proprietary ultra-high tensile strength steel, this spring provides more travel and deflection than standard racing coil springs while maintaining predictable handling characteristics throughout repeated race use.

Designed to preserve its original dimensions and spring rate, the Eibach ERS Platinum spring is built to maintain exceptionally tight tolerances lap after lap and race after race. Its flat-ground end configuration uses a parallel tolerance of plus or minus 1 degree to support consistent seating and reliable suspension operation. The block-resistant construction helps prevent spring height loss, supporting stable vehicle setup and repeatable performance.

This Eibach spring features a 14-inch free length, 3.50-inch outside diameter, and 130 lb/in spring rate for applications requiring a controlled rear suspension response. The lightweight high-tensile steel construction helps reduce unsprung mass without sacrificing durability. It is supplied as one spring and is intended for automotive racing use. Professional installation and suspension setup are recommended to verify compatibility with the vehicle, spring perch, and overall chassis configuration. This product carries a California Proposition 65 warning.
