Eibach ERS Platinum 18-Inch Race 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 race spring is engineered for demanding motorsports applications where consistent performance, reduced weight, and maximum suspension travel are critical. Manufactured from proprietary ultra-high tensile strength steel, this rear spring provides more travel and deflection than standard racing coil springs while maintaining precise handling characteristics throughout repeated race sessions.

Designed to withstand the intense loads and heat cycles of competitive driving, the Eibach ERS Platinum spring maintains its dimensions and spring rate to exceptionally tight tolerances. Its block-resistant construction helps prevent loss of spring height, supporting consistent suspension geometry and predictable vehicle behavior lap after lap. The flat-ground end configuration is produced with parallel tolerance to within plus or minus 1 degree for reliable seating and installation.

This Eibach race spring features an 18-inch free length, a 3.50-inch outer diameter, and a 70-pound-per-inch spring rate. 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 suspension applications. Verify vehicle fitment, suspension design, installed height, and required spring rate before ordering.

What's Included: One Eibach ERS Platinum racing coil spring.

Fitment: Universal motorsports application; vehicle-specific fitment data was not provided. Professional installation and setup by a qualified suspension technician are recommended.
