Eibach ERS Platinum 14-Inch Rear Racing Spring, 3.50-Inch Outside Diameter, 115 lb/in – P1400.350.0115

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 maximum suspension travel are critical. Manufactured from Eibach’s proprietary ultra-high tensile strength steel, this spring provides more travel and deflection than standard racing coil springs while helping reduce unsprung weight.

Designed to maintain its dimensions and spring rate within exceptionally tight tolerances, the Eibach Platinum spring delivers dependable performance lap after lap and race after race. Its block-resistant construction helps prevent loss of spring height, supporting predictable suspension behavior throughout extended competition use. The flat-ground end configuration is manufactured with parallel tolerances of plus or minus 1 degree for reliable seating and consistent installation.
