Eibach ERS Platinum 16-Inch Rear Racing Spring, 3.50-Inch Outside Diameter, 130 lb/in - P1600.350.0130

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 serious competition use, combining ultra-high tensile strength steel with a performance-focused design that delivers low weight, extended spring travel, and consistent handling characteristics. With a 130 lb/in spring rate, this Eibach Platinum spring is designed to provide predictable suspension response throughout demanding track sessions.

Compared with standard racing coil springs, the Eibach ERS Platinum series offers greater travel and deflection while maintaining spring dimensions and rates within exceptionally tight tolerances. This consistency helps preserve vehicle balance and suspension performance lap after lap and race after race. The flat-ground end configuration is manufactured with parallel alignment to a tight tolerance, supporting proper seating and reliable load distribution.

The lightweight high-tensile steel construction helps reduce unsprung mass without sacrificing durability. Eibach’s block-resistant design helps prevent permanent loss of spring height, supporting dependable performance over repeated compression cycles. This automotive racing spring is supplied individually and is intended for applications requiring a 16-inch free length, 3.50-inch outside diameter, and 130 lb/in rate. Verify suspension requirements and application-specific fitment before installation.
