Eibach ERS Platinum 16-Inch Rear Racing Spring, 3.50-Inch Outside Diameter, 100 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 competitive motorsports applications that demand consistent performance, reduced weight, and dependable durability. Built from Eibach’s proprietary ultra-high-tensile-strength steel, this spring delivers increased travel and deflection compared with standard racing coil springs while maintaining precise control lap after lap.

Designed for use with compatible racing suspension systems, the Eibach ERS Platinum spring features a flat-ground end configuration with parallel tolerance to within plus or minus 1 degree. Its advanced construction helps maintain spring dimensions and rate within exceptionally tight tolerances, supporting predictable handling and suspension response throughout repeated race sessions. The block-resistant design also helps prevent permanent height loss under demanding loads.
