Eibach ERS Platinum 18-Inch Rear Racing Spring, 3.50-Inch Outside Diameter, 130 lb/in, Part P1800.350.0130

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 delivers increased travel and deflection compared with standard racing coil springs while maintaining reliable suspension response lap after lap.

Designed with a flat-ground end configuration and tightly controlled parallel tolerance, the Eibach Platinum spring supports precise installation and predictable load transfer. Its block-resistant construction helps prevent loss of spring height, while the high-strength material reduces physical weight without compromising spring performance. The 130 lb/in spring rate is suited to race suspension setups requiring controlled rear-wheel support and repeatable handling characteristics.
