Eibach ERS Platinum 14-Inch Rear Racing Spring, 3.50-Inch Outer Diameter, 70 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, low weight, and long-term durability are essential. Manufactured from proprietary ultra-high-tensile-strength steel, this spring provides increased travel and deflection compared with standard racing coil springs while maintaining reliable handling characteristics lap after lap.

Designed with a flat-ground end configuration and precise parallel alignment, the Eibach Platinum spring supports accurate installation and consistent load distribution. Its block-resistant construction helps prevent permanent loss of spring height, while the high-strength steel design reduces unsprung weight without compromising racing performance. The spring has a 70 lb/in rate and is intended for rear suspension applications using compatible ERS coilover hardware.
