Eibach ERS Platinum 20-Inch Rear Racing Spring, 5.00-Inch OD, 100 lb/in - eibPR2000.500.0100

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 reliable spring travel are essential. Built from proprietary ultra-high tensile strength steel, this Eibach Platinum series spring is designed to provide more travel and deflection than standard racing coil springs while maintaining predictable handling characteristics throughout extended use.

With a 100 lb/in spring rate, the Eibach ERS Platinum spring supports precise suspension tuning for competition vehicles. Its flat-ground end configuration and tightly controlled parallel tolerance promote consistent seating and load distribution. The spring is also engineered to maintain its dimensions and rate within exceptionally tight tolerances, lap after lap and race after race. Block-resistant construction helps prevent permanent loss of spring height, preserving suspension setup and performance over time.

This rear racing spring features a 20-inch free length and 5.00-inch outside diameter for compatible motorsports suspension systems. The lightweight high-tensile steel construction reduces unsprung mass without compromising durability. The Eibach part number eibPR2000.500.0100 identifies this specific ERS Platinum spring configuration. It is intended for automotive racing use, and vehicle-specific fitment should be confirmed before installation.
