Eibach ERS Platinum 5.00-Inch Rear Racing Spring, 85 lb/in – Part Number PR2000.500.0085

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 extended spring travel are essential. Manufactured from proprietary ultra-high tensile strength steel, this Eibach Platinum series spring delivers increased deflection compared with standard racing coil springs while maintaining reliable control lap after lap.

Designed for professional and competition use, the spring features a flat-ground end configuration with parallel tolerance controlled to within +/-1 degree. Its race-focused construction helps maintain spring dimensions and rates to exceptionally tight tolerances, supporting predictable suspension behavior throughout repeated track sessions. The block-resistant design helps prevent permanent loss of spring height, preserving setup consistency over time.

This Eibach ERS Platinum spring is rated at 85 pounds per inch and uses a 5.00-inch outside diameter with a 20-inch free length for compatible racing suspension applications. The lightweight high-tensile steel construction reduces unsprung mass without sacrificing durability. Part number PR2000.500.0085 identifies this Eibach replacement or setup component. One spring is included. Professional installation and suspension setup are recommended to ensure proper fitment, preload, and compatibility with the vehicle and race application.
