Eibach ERS Platinum 14-Inch Rear Racing Spring, 3.50-Inch Outside Diameter, 100 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.

• 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
• More Travel / Deflection than Standard Racing Coil Springs
• Ultra Light-Weight Using High Tensile Steel
• Block Resistant - No Loss in Spring Height!

The Eibach ERS Platinum rear racing spring is engineered for competition vehicles that demand consistent performance, low weight, and maximum suspension travel. Part number EIBP1400.350.0100 uses Eibach’s proprietary ultra-high tensile-strength steel to deliver a lightweight spring with dependable rate and height stability throughout repeated racing cycles.

Designed for demanding track use, this Eibach Platinum spring maintains its dimensions and spring rate within exceptionally tight tolerances, lap after lap and race after race. Its flat-ground end configuration provides precise, parallel spring seating, while the increased travel and deflection capability help the suspension operate effectively over a broader range of motion than standard racing coil springs. The 100 lb/in spring rate is suitable for custom competition suspension setups where accurate tuning and predictable response are essential.

• Lightweight Competition Construction: Ultra-high tensile-strength steel reduces physical weight while supporting demanding racing applications.
• Consistent Rate and Height: Designed to maintain its dimensions and spring rate within tight tolerances through repeated track use.
• Increased Suspension Travel: Provides more travel and deflection than standard racing coil springs for improved suspension tuning potential.
• Precision Flat-Ground Ends: Flat-ground end configuration and parallel tolerance help promote accurate, stable spring seating.
